SLR Rifleworks Mag Wells for Polymer80 PF940v2 Frames Are Great

When I first looked at the Polymer80 PF940V2 Frames, these are the full sized frames you’d use to make a Glock 17 or 34 compatible pistol for example, I noticed the magazine opening was narrow, had a minimal bevel and there wasn’t a ton of supporting material either. Cosmetically, to me anyways, it just looks unfinished.

I’ve had a number of pistols over the years and found aftermarket magwells very beneficial for two reasons – first, they help guide the magazine into position when you are in a rush and this is the biggest reason. Second, they can protect a polymer frame from a ton of abuse.

What I found out after doing some digging was that Glock mag wells will not fit the PF940v2 frame, which isn’t surprising. The one thing you also need to know is that the PF940v2 full size frame and the PF940C compact frame also use different magwells. A vendor accidentally sent me a C-series magwell and it absolutely would not fit my full size frame.

So, I did some digging and you’ll notice there are magwells of differing sizes with some having a very wide flare and some have more moderate flares. What I did find surprising is that a cottage industry has popped up on eBay sellding 3D printed magwells. On one hand, they are really cheap. On the other, I question how long they will hold up to real world abuse. I definitely knew I wanted an aluminum magwell.

I settled on a unit from SLR rifleworks. It is nicely made and fits the PF940v2 grip really well. I was so impressed that I bought a second and now have them on both my G17 and G34 pistols. My G17 is the grey pistol in the photos and the G34 is the olive drab pistol. Both are based on receivers built from PF940v2 frames.

Here’s the view from the bottom.

Installation is simple. Insert the front of the grip into the front of the magwell at an angle and then push the back down to fully seat the unit. Put a bit of blue medium strength Loc-tite on the screw and screw it into the hole that is drilled in the back of the frame and you are done. Even though the used a flat head screw for presumably an even more secure hold, you can’t feel it when you are gripping the pistol.

Note that you tip in nose first and then push down the back to seat it properly.

Here’s the bottom. No, this is not a paid review. I just really like the mag well.
I’ve not had problems with any magazine fitting or dropping free. This is an OEM glock 17 round magazine and it’s also worked well with 33 round Glock mags, plus both 22 and 31 round ETS mags.
Glock 34 compatible pistol with a Streamlight TLR02 HL G light and laser plus a Tyrant Designs brake.

So, I’m very happy with the results and have no hesitation recommending them.
