The Master Blaster is undoubtedly the most minimalist combo Appendix KYDEX IWB holsters on the market. Typically called a sidecar holster, the Master Blaster follows the same style, with a twist. With the standard construction of our normal IWB holsters, the Master Blaster, or sidecar holster, has a small angled off-shoot that carries a backup magazine. The holster uses our standard IWB single belt clip; this makes putting on and removing your kit a breeze!
Master Blaster, or sidecar holster, comes standard with the magazine (rounds) facing the firearm. It utilizes a single adjustable bushing to adjust the retention for the magazine. The Master Blaster, or sidecar holster, is only offered for single-stack, subcompact firearms.

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.

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.

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.

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

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.

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

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!

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”

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!

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.

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

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.

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.

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.

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!

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

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.

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

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.

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

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….
