P80 PF940Cv1 Compact

[BobbyC]

Oh man, let's hope that tweaked frame is not how all of them came off the injection mold. That would be worse quality control than the trigger housing defect on the pf940....

There were a few that had PF940 frames that curved downward at the front. Mine was perfect. There's a few Glock frames where the front curves upward. The twist looks very minimal and as long as it functioned properly, it wouldn't bother me.

I wouldn't exactly call the trigger housing pocket a defect. More of a tolerance issue so if you were slightly off with the rear pin hole, it would still work. Yeah, having a shim isn't the best but it hasn't bothered me at all.

Also remember these are 80% polymer frames and not complete products. There will always need to be some work required for fitting. You will most likely be disappointed if you get into this expecting perfection. Especially if you're not handy with tools.

It functions 100% so far, but when you aim, you can definitely tell the slide twists. This is what bugs me.

If it bothers you, send P80 an email. I never dealt with them but I hear they're very good about this stuff.

There were multiple things out of spec with the pf940: trigger housing was the wrong dimensions, the housing pin location doesn't change that. The magazine release was out of spec as well. Many folks couldn't use magazine releases that worked in regular glocks. The slide lock channel is out of spec (wrong angle).

I'm not trying to rip on polymer80, these frames are awesome, but I'm not going to pretend there aren't issues. I don't think polymer80 denies these issues either, which is why there's now version 1.5

The trigger housing issue is dangerous, the rest of the issues are just annoying.

If I were to criticize p80 for anything, it would be setting an overly optimistic ship date which ends up pressuring them to meet a deadline. I'd much rather wait an extra 2 months for a higher quality product. Snice I see people cancelling their orders and reordering with rainier to try and save a few days, I guess p80 needs to cater to the "instant gratification" crowd on this.

I tried a EP 80 ar lower a few years ago when P80 just announced they were bringing one to market. They were very good answering questions via email and on social media. The EP 80 had too many issues. They sent me a replacement and it was also off so I scrapped it and just bought a forged lower since I had a bunch of parts.

I did a lot of research on the PF940 before ordering one. I ground down the slide block screws a couple of mm so it wouldn't get in the way of the rsa. I cut a piece of credit card for the trigger housing (15mm x 51mm). I reamed out the 5/64 pin holes to 3mm, the trigger pin fit fine. I found the dimensions of the slide rails and cut the rear rails to match. It took very little time to fine tune the rear rails and my slide went into battery when pulled back 1/2" every time. Took it out a couple of weeks ago and shot flawlessly for about 120-150 rds.

I was expecting some issues but after my research, it was painless. So easy (for me) that I couldn't wait for the compact version.

I've finished the v1.5 and several v1 and found all the same issues with both versions, personally I cancelled my "preorder" with brownells because I would feel like an idiot waiting 3 more weeks than I have to when the product is already released, it actually completely defeats the purpose of "pre ordering" imo, lets say you preorder a new car in December that comes out in march then you see it on a showroom floor ready to drive away but yours is still nearly a month out... although you do have a point, they may have used a new Revolutionary-Evolutionary Polymer compound that over the next 2 months becomes a better product, I will set up a time lapse camera on a frame for 2 months exactly so we can monitor this new amazing process taking place which I think will also definitely be a great learning experience for those of us in the instant gratification crowd!!!

And yes I overnight every package every time next day air Por vida

In my experience, they're very good unless the problem is a fundamental design/manufacturing flaw that they really can't do much about...except refund your money...which they won't do.

[Nelson_2016]

That would bother me as well.

I'm guessing that the rails are not coplanar; that is, the rail surfaces are not in the same geometric plane.

Also, it's hard to tell from the pictures, but from what I can see the rear rails look to be significantly longer than those found on a Glock factory frame. (On my Glock 17 for example, the rear rails are only about 0.39" long).
While this difference in length shouldn't necessarily be a problem per se, it seems to me that the longer the rails are (unnecessarily in this case), the more accurately they would need to be aligned.

It functions 100% so far, but when you aim, you can definitely tell the slide twists. This is what bugs me.

"It looks like you drilled the pin holes on the right side of the frame at enough of an upward angle to actually lift the LBRS and RRM up on that side. You can see the RRM rail flange on the right side is slightly higher than the left, and it also looks like the LBRS isn’t touching the top of the frame on the same side either. I do believe the frame will work but seeing as you preordered I know you want this frame to be top notch and I am willing to send you a frame and jig combo but it will come with no rails and I will need a photo of your lower destroyed."


They are awesome!

So once again, it looks like operator's error :-)

[BobbyC]

Nice! Glad to hear they stepped up.

I've heard a lot of guys having to destroy the lower and send a pic when they replaced it. I think it's SOP.

Still impatiently waiting for mine

[Nelson_2016]

I'm glad they're sending you another frame, but IMO the "error" is in Polymer80's faulty instructions. They're telling people to use a hand drill, even though it's possible to cant the drill and significantly displace the holes.
IMO they should recommend using a decent quality drill press and if necessary make a video showing people the proper technique of using it with the jig.

I read the instructions and Poly 80 recommends a hand drill and regular vise to drill the pin holes. Apparently because people clamp the jig improperly when using a drill press and distort the pin location by distorting the jig. I'm thinking builders should start the holes with a reg side mount bench vise, then use a leveled drill press to drill the pin holes but use a C-clamp or similar top clamp etc

[Nelson_2016]

I suppose anything's possible, but I can't imagine anything a person could reasonably do with any kind of clamp that would distort anything bad enough to mess the holes up.

IMO a drill press (or better yet, milling machine with a collet chuck) is the only way to go, but some care and proper technique are required.

[BobbyC]

The problem is that most people that use drill presses don't know how to zero the drill and platform properly and/or align the bit to the hole in the jig. It can be off and the press will continue on the wrong path whereas a hand drill will "drop" into the hole in the jig and self correct. The problem with a hand drill is being perfectly perpendicular with the jig. There's a little room for error but a reason why you drill each hole separately and not straight thru for the hole on the other side.

I just got my tracking # from Rainiers

[NguyenLe]

But, Slide to frame fit without any hardware = off....anyways, gonna do this on the new frame before i install anything.
