Question: Would one of these fit a 4" XDS? Thank you in advance.
Document: First holster I've ever owned that fits multiple pistols. I bought this for my full size Smith and Wesson M&P .40 and not only did it fit perfectly but it fits my FN full size FNS .40, my Ruger SR40c, and gen. 4 Glock 21. I had to slightly adjust the tention screw just a bit. So yes....hard to believe but this holster fits all four and secures them properly. Very impressive. Thank you Blackhawk!! !
This holster will not fit a Glock 21 SF gen 4 firearm. I wish the documentation would be more specific on which Glock models are supported because I am out return shipping (even as a Prime member).
I already had this holster for my Glock 17. While the 26 fit in it, I wanted one that wasn't so large, for the smaller gun. It performs just like its bigger brother. Very well. I would recommend it for a range holster, but nothing that I would take into public any where. It is kind of lose, and there are many other holsters that are more secure.
Great holster, but a Gen 4 Glock dosent fit!! No problem with a Gen 3.Very comfortable to wear, holds weapon nice and secure, easy quick draw.
High quality and fancy looks for this great holster. Perfect fit for ever model.Why only 4 stars? If in a fight, the holster may be snapped off if forced out and upward. If using for an off-duty or ccw holster, don't forget to try out a leather holster as well.
I bought this Blackhawk Serpa for my wife and her Gen 4 19. I originally bought a different manufacturer but she was unable to draw her weapon consistently, so after researching again, this is our purchase. Works great! The fit is good when she's at the range, holds her gun securely and she draws smoothly. Couldn't be a better solution.
So this is my first holster that I bought for my Glock 22 .40 cal gen 4 and I'm pretty sure i wont have to buy another one for some time if at all. Smooth putting in and taking it out of the holster. Great release design. Not flimsy and well put together. couldn't be happier
I have a Glock 21 Gen 4 and this holster is a perfect fit. I ordered the size 13 holster since that was the size that fit my Glock. However, I was not too crazy about the light gray color of the holster and my Glock cannot be concealed very easily unless I wear baggy clothes but that is mostly due to the size of my Glock and not the holster. But for a holster that is under $30 you cannot beat the value.
This fits my gen 4 Glock 26 perfectly (size 1). I also have the glock sport/tac holster. This one is way better. The draw is so much smoother with this holster than any other I've ever used. Bottom line, if you're looking for a holster to wear to the range and practice a smooth draw, every time - look no further.Marc
I've never been a fan of paddle holsters because they never seemed to feel that well against my hip. I prefer belt-looped holsters. This one was pretty nice. I was able to adjust the cant just a few degrees forward and the paddle cinched in well with a belt at the waistline. For me, the auto-lock pushed this holster into 4 star status. The Glock 27 with full magazine has significant weight, specifically in the mag-well, and having this secured to waistline is a priority.
