This is a PF45 build and I'm not going further until I decide how much of a problem this is. I was in the process of fitting the rear rails. I've been waiting on Rook rails for the PF45 to start this build, but not holding my breath any more. As you can see in the first pic, the trigger housing sits crooked in the frame. This is with the pin in, which went in no problem. In the second pic, the rails are removed and the housing sits more straight. The pin is also in in this pic. The bendy tab on the right rear rail is obviously pushing the housing to the left, and there is just enough slop in the pinhole of the housing to allow it to be crooked. I have one other housing, a Lone Wolf for PF45, and it behaves the same way. I can take some of the bend out of the tab on the right rail to make it sit more straight, but then I'm concerned there might be some slop in the housing. But, if I don't correct it, then I'm concerned about binding in the trigger bar, and maybe some mis-match in how the two sides of the cruciform ride on the drop safety ramps. Capiche? What do y'all think?

In the end, it doesn't matter. Just do a little at a time and you'll see it begin to fit right in.

Either way, I don't think Rook rails will do anything for this problem, and unless there's different versions of the PF45 frame out there, I guarantee you'll have this problem. One thing to notice concerning the trigger bar: If you look at the picture with the trigger installed, you will see that the trigger bar appears to be hitting the rear rail at the bend. I got a pretty shitty set of stock rails in the kit and I shaved down this area enough so that the trigger bar hits the polymer before the rail. Noted. Nope. Nor PF45 Rook Rails and I don't see any in my future.

Awesome he’ll yeah, glad you got it figured out.

Problem solved! It was pretty much exactly as MGB described in his PF45 Trigger housing fix video. Basically, the trigger housing and the frame are incompatible because of a raised ledge on the curved portion of the frame where the rail sits. Rule #1 is modify the part, not the gun. So, the housing needed to be sanded down/shaped to allow it to sit properly in the frame. First pic shows the raised "ledge" that the rail sits on, which protrudes too far for the housing to fit up against the rail. Second pic shows the modified LW housing next to an OEM housing to see what material I had to remove to get it to fit. Last pic everything fits and is functional. Next step, clean everything up, polish, and the fun part!

On one of my ss80's a few years ago I had a rear rail that the tab holding the housing was bent to out too far. This let the housing move slightly. All I did to fix this was bend it back so everything would fit snug. It is important for the housing to fit tight, if it is loos you will have the same problems as if the connector is not bent right. Once you get some Rook Rails this will not happen. These stamped rails that P80 uses are crap. You have to sand all the edges and pinch lines.
by Ancient Order » Mon Aug 15, 2022 11:13 pm Ok, this was a test. Haha. I'm such a dumbass. Should have watched MGB's PF45 trigger housing fix first. I haven't applied the fix yet...will do that tomorrow. But looking at all the symptoms, I'm convinced that's the problem. (Doing the flat forehead). In retrospect, it's kind of disappointing that P80 didn't discover this problem when designing the PF45.

On Rook rails, instead of a tab, the right rail is thicker to perform the same task. This is a really interesting problem. The plot thickens. When I tried the connector + trigger bar/spring - the holes won't line up, pin won't go in. The housing won't sit down all the way. Tried it with just the connector installed and no trigger bar...and again, the housing will not sit down all the way. I even bent the connector all the way in, and it still won't sit down all the way (second and third pic). No connector installed, no problem. There doesn't appear to be any problems with the frame from visual inspection. I guess the next step is to bend the tab on the rails to give a little more clearance and see what happens. Oh yeah, after watching MGB's video on PF45 issues. Ya know what, I misread. You said you have a Lone Wolf housing and I was thinking you had a 2nd rear rail with the same problem. My bad. Anyway, sounds like We4ponXYZ gave you the solution. Let us know how it works out.

The little tabs that grip the housing have been known to be bent in too far sometimes pushing against the sides of the housing and can cause this issue. Or the housing mold swelled just enough.The fix is to sand a little bit of material off of the inside of the rail tab, check rinse repeat. Just enough sooo it isn’t pinching the housing to hard anymore. When attempting to bend it you can potentially twist the rails soo this way is a bit safer. As long as the rail itself is in the correct shape afterwards this should fix your issue.

Can you point out exactly what you're talking about when you say, "The bendy tab on the right rear rail is obviously pushing the housing to the left...". You also said, "I have one other housing, a Lone Wolf for PF45, and it behaves the same way...". That might indicate something wrong with the frame on the inside. What does it look like with the trigger bar and connector installed?
