S&W M&P9 4.25 inch barrel ShapeShift 4.0 IWB Holster

$55.88
Plenty of S&W M&P9 IWB holsters are out there. No doubt about that. But how good are most of them to actually carry with? A lot of them leave a lot to be desired. Uncomfortable materials, strange fit and retention that you just have to live with because you can't adjust it. Then there's dealing with how a holster designed for a full-size firearm can get enormous, which isn't the most pleasant to wear.

Amazing how hard it can be to find a decent M&P9 IWB holster.

That's what Alien Gear set out to fix. When we created the ShapeShift line of holsters, we didn't want to just make a couple little things better on holster designs we already made. We wanted to make a better holster than we or anyone else previously had.

An M&P concealed carry holster that was comfortable to wear. That still let you adjust grip cant, ride height and retention. That also had less of a footprint inside the waistband. And that's exactly what we're offering.

How is it really different from other holsters?

First is the holster shell. The new ShapeShift shell attaches at one point, rather than at multiple points. It locks in place, so it can't come apart unless you take it apart. The trigger guard is also fully wrapped, offering more security than many other designs.

Since the shell itself can occupy less space, that means the backer can be reduced in size, losing about 25 percent of its surface area. That means an IWB holster for a full-size gun that takes up the space of one made for a compact.

The backer is a multi-layer design optimized for greater comfort. The backing is our Cool Vent perforated neoprene, which wicks away moisture and breathes, which is reinforced with a layer of spring steel. This gives the holster a firm but flexible spine, flexing to adhere to your shape but retaining enough rigidity to carry securely.

You can have your choice of belt clips, which can be adjusted for ride height and grip cant and without the need to track down an Allen wrench.

Sounds great, doesn't it? Sure, but what someone says about what they make and how you experience it are different things.

That's why our guarantee includes a 30-Day Test Drive after purchase. We give you the first month to wear the holster and see if you like it. Return for a full refund if not before the first 30 days is up.

We also warranty the holster for life.

Why not shift to a better carry?

probably the best IWB holster I have ever had. Easy to use, good retention and comfortable. I have been using it for over a year and it has held up great. I would like to have had mental clips, but other then that , it's perfect for my needs.

Excellent Review by sdharvey

I got this holster about a month ago now and I have worn it every single day so far. I have not had any problems or discomforts out of the holster itself. I have come to find that any discomfort I do have though is from the size of the gun itself. I highly recommend getting this holster, My favorite thing about it is the retention. I never have to worry about it accidentally falling out. I also love that its tuck-able since I wear dress clothes almost every day. I did a lot of research prior to picking this and I am so glad that I did. I will be buying more shells for my other pistols as well.. (Posted on 8/7/2019)
Florida tested Florida Approved Review by Tactical Waffle

I am relatively new to conceal carrying and love my full size sig P-320, but I live in Florida and thought that even with this holster I would be incapable of carrying it unless it was winter or as close to winter as Florida gets and under at least a hoodie or large coat. I was astonished to be so wrong. I have carried this in the Florida hot humid summer sweating my ass off and yet the sig stays dry the holster gets a little damp but dries quickly and is always super comfortable. I conceal at the 3:00 position with a foreword cant and I can bend over, sit down and drive with my beast of a gun concealed as ever. I decided to actually really push my limits with this holster and helped a close friend move today. Even with my firearm and holster I was still able to comfortable move boxes get in and out of truck beds (sometimes by jumping), move couches and was still comfortable and concealed without an undershirt and wearing nothing other than a pair of cargo shorts and a black sleeveless shirt. Alien Gear FTW
PS: I took a nap wearing it by accident it was a comfy nap 10/10 (Posted on 7/31/2019)

I have worn this holster every day for a couple of years now. Still looks almost new after 365 day use. Very comfortable, you almost forget you're wearing it. Worth every penny. Wears well no matter what season. Doesn't print and no one knows it's there. Comfortable standing or sitting with great retention of firearm. (Posted on 7/12/2019)

Bought my shapeshift 4.0 after a police officer highly recommended alien gear. I have been through a lot of different holsters for my full size .40 cal and I'm pretty demanding and alien gear by far is the best of the best I've ever had and used. Very versatile with its options and adjustability not to mention I forget I'm wearing it at times . I'm going to expand on my 4.0 system . I love it's made to fit my gun and the fact I can actually get it in left handed. No regrets. A must have for anyone (Posted on 7/2/2019)
Good quality and design BUT adds 4" to waist Review by Fatso
Quality

This is honestly a really nice holster. The materials and design are great. I like that everything is modular and can switch things out and customize it. HAVING SAID THAT... This holster is basically useless to me. I wear a size 32 waist and have gained a little weight in the last year or so. I cant wear this holster with any of my current pants. So this isnt really a problem with the holsters design or construction but with me being a fatty. Just know that if you get this holster you will need to size up 4-6" inches on your waist for it to work. I had to get a size 38 to make it work. I dont feel like buying a whole new wardrobe so Ill probably try something a little smaller. Id honestly return it as its useless to me now but I dont have the box anymore and with shipping etc it doesnt seem worth it. Thats one of the risks I guess. (Posted on 6/29/2019)
Great holsters Review by MIke

I bought my first one for my Glock 29. I have a medium frame at 5' 6" and I was amazed at how comfortable this holster is with that wide gun. I wore it everywhere for a week and barely noticed it. Make your adjustments and the weapon stays put! I bought one for my Glock 26 and plan to buy another for my Glock 43. Absolutely GREAT holsters. BTW, I rarely write reviews on anything...this one was very easy! (Posted on 6/12/2019)
Extremely comfortable Review by Dan R.

This thing is great. Never thought I'd be able carry a full size 1911 so comfortably. And for only around $55. That's pretty mind blowing. A plain Kydex holster costs more than that. The combination of functionality, customization and value is unmatched, in my opinion. Highly recommended. (Posted on 6/11/2019)
