    The master blaster is the best IWB holster on the market in my opinion came across this holster on the Sig Sauer website. This was holster number 4 and the last. The master blaster is perfect, comfortable, and the retention is excellent. I wear this holster while at work (construction), when wearing tool bags or harnesses, there is no discomfort or hindrance with the belts or strapping. The holster is also easy to clean and adjust the retention. Only wish I would have come across this sooner.

      Thanks Jeremy!

    Amazing custom build with attention to quality and detail. Fits snug and comfortable up against my body, keeps the gun and magazine secure, and easy to un holster.

  3. Randy (verified owner)

    Best holster I’ve ever bought! Super comfortable and well worth the money.

  4. Kyle Hoskison (verified owner)

    This thing is awesome! So comfortable for its size and solid as a rock. It looks great and it fits the aftermarket magazines as well.

  5. Jonathan Le (verified owner)

    I got this used for a P365. Best holster for carrying a micro gun with a mag. Feels like I’m wearing nothing at all.

  6. Tom (verified owner)

    I have many holsters from ANR. They are all high quality, and ANR has excellent customer service. Highly recommended.

    I have the Master Blaster with Claw for a M&P Shield 9mm/.40 cal

    Fits great and conceals so well — belt clip is totally secure even when you don’t pull straight up out of the holster to draw (I know, what a stupid way to draw appendix but stress and fear make mortals weak)

    Extremely comfortable when sitting in the car — my woman gets worked up (in a good way) when she moves in for a close hug and feels the presence of your holster between us

    I’m waiting for the M&P Shield 9mm EZ version before I switch to the EZ for EDC — can’t wait

    Impressive quality, workmanship, and design

    Outstanding rig for my Sig P365. This is my new go-to EDC rig! Well worth the wait. Excellent fit and finish. Great retention of the gun and mag. VERY comfortable and conceals very very well.
    I well be ordering more ANR rigs for my other guns

  9. Kyle Wheeler (verified owner)

    Looking for the most compact all-in-one side car style holster, this is the best! Snagged it for my PPS M2 and it doesn’t disappoint. Glad to know that these are still being made after all this time. Quality and fit were top notch. Word of wisdom, just upgrade to the Monoblock clip. Worth it every time!!

  10. Andre S (verified owner)

    Overall great holster, however I had to cut off almost half an inch from the top of the claw because every time i tried to grip the gun while it’s holstered middle joint on my middle finger kept hitting/scrapping the top of the claw.

  11. Art (verified owner)

    Great holster. Very comfortable. I can actually tie my shoes my while wearing this holster. 4 stars only because I specifically asked if the P365 holster would work with a red dot. To which, the answer was yes. I had my slide milled keeping the rear sight. Didn’t fit. It was very disappointing. I can’t even grind away material to fit. Perhaps it would’ve fit if I had the rear sight removed. I wish I would’ve been told that. I was really looking forward to using that setup for EDC. Another thing I don’t like is the claw moves around sometimes. A more solid mount would have been better. I would still recommend this holster and will probably get one for my HellCat when available.

  12. Austin (verified owner)

    My first ANR holster and first AIWB as well. Well made w/ quality materials. Fits my M&P shield perfectly and the adjustable retention is a nice feature. Shipping was faster then advertised. It is comfortable when walking and standing. It can start to pinch after longer periods of sitting, which isn’t a real surprise. Overall I’m very happy with it and will probably order again for other guns.

  13. Jameson B (verified owner)

    Somehow this holster is exponentially more comfortable than a standard kydex holster. The curve is just right and doesn’t pinch anywhere, even with a big stomach. I’m very impressed!

  14. J Lo (verified owner)

    Well made. P238 set up. Fits well and the sidecar is a def perk. Great for single stacks.

  15. Jeff Morris (verified owner)

    Purchased this for my sig 365XL and love it. Feels great, and even though it carries an extra magazine it isn’t big and bulky. Easy to draw from and optic works great with it as well. Great job ANR!

  16. Ed (verified owner)

    I have a few ANR holsters now, including the Master Blaster w/claw for my S&W Shield. The holster is top notch, I recommend them to anyone looking for a good holster, especially IWB. I just ordered one of these for my newly acquired G43x as well.

  17. Eusebio Travis Sevilla (verified owner)

    This is my 3rd holster from ANR and once again it’s perfect. I have IWB holsters for my P-10c (lucky to get since I’m in CA). I have one for my Glock and now one for my Shield. Quality products to go along with my new Vastus Strap in my battle belt set up. Thanks for the great products and for being our “gun Siri”

  18. Tyler S Kulp (verified owner)

    Purchased a master blaster for my Walther pps m2 in blue carbon boltaron. Could not be happier. It balances beautifully and has a tiny footprint. Great craftsmanship, no rough edges. Allows you to carry a backup mag and is honestly more comfortable than my previous gun-only holster that I also liked very much. Well done ANR!

  19. William Allyn (verified owner)

    So, I don’t normally take the time to leave reviews, as I feel most of them are subjective anyways. BUT, with that being said, this thing is amazing! The holster is smooth, with great retention, and just the right amount of cant on the mag carrier. Whatever these guys are doing, they need to keep doing it, and teach some others.
    Also, the customer service is the best, hands down. There was an issue with the first holster I received, and if by magic, I was in contact with someone at their shop, had a return label in my inbox, and my new holster on its way.
    Seriously, spend the money, wait your turn, and gift yourself one of the best holsters out there.

  20. Aaron (verified owner)

    Fantastic holster! First off, ANR beat their own lead time, super quick. Holster is of great quality, and retention adjustment is easily adjustable. Super comfortable.

  21. Shane Lamb (verified owner)

    So I have more than a handful of the standard IWB holsters with the claw from ANR, but never carried an appendix rig from any company. Well, after talking with alex and another one of his customers, I had to try out to Master Blaster for my Glock 43. Hot damn, did they come through. Fit and finish are by far the best i’ve ever had on any holster. It totally makes your gun and extra mag disappear and is extremely comfortable. I have a little extra on me so I was worried about concealment and comfortability with carrying an appendix rig, but nope! Can’t tell I even have weapon on me and sitting down in a car or in a chair is nothing. You can’t go wrong with ANR holsters. Hands down best holsters on the market for concealed carry. Don’t hesitate to get one, just buy it.

  22. Mark L (verified owner)

    Purchased for my Walther PPS M2. When I received the Master Blaster with Claw, I looked it over and was impressed by the design, cant, smooth edges, size, and thoughtful design to hug the wearer’s body. When I put my PPS M2 in with the extra magazine, I was more pleased with the feel and additional concealment the Claw provides while adding additional capacity without adding bulk. Even if you have love handles, the sweat guard isn’t high enough to dig in and you can still wear apendix in relative comfort. Fit, form, function, finish,and comfort are difficult to find in one holster but the Master Blaster with Claw does so with ease. If you’re having any second thoughts about the cost compared to other brands for half the price, buy quality once and you’ll see and feel the difference immediately.

  23. PHILIP GRIFFIN (verified owner)

    I have had this holster for a few weeks now and it has been outstanding. I have been in law enforcement for over 25 years and have seen many holster designs, this is the best executed appendix holster I have used. The design is very well thought out with the right depth, and cant for excellent concealment.

  24. Timothy Tacy (verified owner)

    Quality holster. Extremely comfortable to wear and perfect fit for my Glock 43X. This has become my favorite holster.

  25. Peter (verified owner)

    Carrying a SIG 365XL ? The master blaster is a great holster. Bought the mono block clips , really like it a lot thanks.

  26. Travis James (verified owner)

    I was blown away with how great this holster is. Been back and forth for months. Got super high one night and pulled the trigger. Best purchase! And in blood red! I will be rocking the master blaster for all my gats now

    First time buyer at ANR designs. Overall top notch Holter for my M&P shieldplus. Very comfortable and easy to put and take off.

  32. Coleman (verified owner)

    I just got my master blaster for my Sig P365 and I love it already. I’m a pretty thin guy and I can’t make this thing print if I wanted to. It is super comfortable and you can really see the quality of work. All the rest of my pistols will have ANR holsters for sure. Great product!

  33. Jeff (verified owner)

    Great holster, conceals my xds great, very comfortable, I added a ultituck and this is the best holster I have owned.

  34. Josh (verified owner)

    I love my Master Blaster for the P365 XL! I was worried about comfort and concealment because I’m only 5’8″ and have a dad bod which makes holster shopping that much worse, but I’m very happy with my purchase. ANR was generous with the optic cut. The holster is very secure on the belt and won’t twist off easily as I’ve seen done in entanglement training, yet it’s super easy to put on and take off. The minimal size and contoured shape is comfortable all day whether I’m sitting/driving or moving around a lot. Retention of the gun and spare magazine is ideal right out of the box. I can’t say enough good things about it at this point.

  35. Dan Robson (verified owner)

    Great holster for my P365XL. Concealment, fit, & finish are all top notch, but the design is the best attribute. I normally don’t carry appendix because I’m bigger guy, but this rig works, and it works well. More comfortable than any other appendix holster I’ve tried. A couple of my friends have the same rig and recommended it to me – all three of us have the same opinion.

  36. Sean (verified owner)

    Have bought two master blasters so far. Amazing service, amazing quality and fit. Also love the Crye Multicam Black.

  37. Chris Garcia (verified owner)

    I am very happy with my holster. Alex was very helpful and quick to answer my questions. The holster fits perfectly and is very discreet with no printing. I will be purchasing more in the near future along with some other optics and mag carriers. Love the quality of the product!

  38. Alex (verified owner)

    Holster was no joke, pistol and mag fit perfect and retention was excellent for pistol and very good on mag. Fit amazingly well to body w/ excellent position and concealment.
    I was very impressed with what I thought would be a benign purchase

    • Alex Costa (verified owner)

      Thank you Alex!

  39. Mason (verified owner)

    This is my first purchase from ANR design. Got one of these for my s&w shield and like it so far. I have to lift a lot heavy items at work throughout the day and its very comfortable while bending over and sitting due to its curved shape. Like others i have a bigger mid section so it does pinch a little after long periods but its not the holsters fault. Qaulity and finish are top notch, i will definitely be buying another holster from them!

  40. Chris Garcia (verified owner)

    This was my second holster that I purchased from ANR. I was so pleased with the quality of the kydex and and how greatly it concealed against my body. I will continue to purchase my holsters and other accessories from this company for the rest of my firearms and firearm accessory needs. The Alex and the customer service team are very friendly, very supportive, and very knowledgeable when it comes to answering questions about the products and offering recommendations.

  41. Mat (verified owner)

    It would be better if it were more customizable/adjustable. It’s a very ok hoster.

  42. Mike Kuntz (verified owner)

    I’ve been running the master blaster with claw for my sig 365x now for a few months, definitely well worth every penny and then some. As a professional automotive technician it is one of the most comfortable rigs I’ve ever owned. Very rarely do I have to remove my edc during the working hours

  43. Michael (verified owner)

    Bought the Master Blaster for the Glock 43x. Very comfortable and makes the gun virtually disappear. Will definitely be buying another holster soon.

  44. Asa (verified owner)

    Fantastic holster. Very comfortable to wear.
    Very quick shipping.

  45. Jiujitsu13 (verified owner)

    Great holster. My P365 with XL grip module fits great, it conceals well, and is very comfortable. I highly recommend it.

  46. Lance (verified owner)

    Tough, comfortable and reliable! What more could you want. I can even wear this when I drive. Very comfortable.

  47. Harry Aguila (verified owner)

    The holster is very well made and conceals extremely well. Also, once accustomed to the holster, it is very comfortable. However, I believe that for the Sig p365 there is not enough weight below the belt line. This is no fault of the holster, which works well with a bit more fidgeting when sitting and standing. But I would prefer to carry a slightly larger gun AIWB. I will be ordering the same holster for my Glock19.

  48. Eric S. (verified owner)

    Great product, a minimalist’s dream. I have the rigs that take up your whole strong side and carried a spare mag on the other side. Sometimes I felt like a deep-sea diver with all the weight. With this holster, it’s light, comfortable, uses just one clip to hold securely on your belt, and carries my firearm and a spare mag. It’s never in the way or feels cumbersome. I have a whole box full of holsters I can finally get rid of, this is the ONE….

    • Alex Costa (verified owner)

      Thank you Eric!

  49. Colin Dawson (verified owner)

    Great looking and feeling holster. I enjoy the availability of an optic cut for smaller pistols. My only complaint is that it sits a little high on the belt so it had a tendency to flip out and print. Nothing that a wedge can’t fix. Not a big problem especially for the great price, quality, and turn around time.

  50. Chad (verified owner)

    Great holster. Most comfortable holster I own. No issues standing or sitting.

Frequently Asked Questions

What is a deep concealment holster?

A deep concealment holster is designed for maximum concealment with the smallest possible profile. The Master Blaster is purpose-built for subcompact and micro-compact firearms, allowing you to carry with minimal printing even under light clothing.

Does the Master Blaster support weapon lights?

No. The Master Blaster is designed as a non-lightbearing holster to maintain the smallest possible concealment profile. For lightbearing subcompact holsters, see our standard IWB builder.

What is a concealment claw?

A concealment claw is an injection-molded accessory that tucks behind your belt line and pushes the grip inward, reducing printing. Available in Black, OD Green, or Coyote for $12.

What warranty is included?

Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell — automatically, on every order. No registration, no added cost. If your shell ever cracks or breaks under normal, intended use, ANR Design will replace it. The warranty covers the original purchaser only. Hardware, cosmetic wear, and damage from misuse are not covered.
