RGC Posted April 3, 2021 Share Posted April 3, 2021 (edited) I just received my new DW PM9. Just to note prior to my rant, I have owned 50 or more 1911s and have gutted nearly all of them. So VERY familiar. I spent 45 minutes of my life wasted trying to seat the firing pin in my new PM9. Seriously. I believe the slide missed the chamfer station. I cannot get the firing pin end to slide into the FP slide opening. One of those “are you kidding me” afternoons. Side note, I swapped out internals and have a trigger drop at 1.8lbs though. But still no firing pin installed....unbelievable. Edited April 3, 2021 by RGC Link to comment Share on other sites More sharing options...
TheSandMan491 Posted April 3, 2021 Share Posted April 3, 2021 Well, the firing pin goes into the slide, not the frame. So that might be your problem. Link to comment Share on other sites More sharing options...

Or the firing pin won’t come out the front of the Breech face? I’m trying to picture the issue. Link to comment Share on other sites More sharing options...
RGC Posted April 3, 2021 Author Share Posted April 3, 2021 Funny, but cannot install it....drop spring in, then FP. Cannot get it to seat in the last 1/4”. I have done this literally thousands of times. Believe no chamfering and the FP hole in slide is flat based so inserting the FP is all luck.

ltdmstr Posted April 3, 2021 Share Posted April 3, 2021 The tightly wound end of the firing pin spring gets mounted on the firing pin prior to installing the parts into the slide. Some slides have a ridge near the breach face end and you could be getting hung up on that. Try pressing the spring in so the back end of the firing pin is flush or below flush with the groove cut in the slide for the firing pin stop. If that clears the machined surface the stop should go in unless it's getting hung up on the extractor. On that, make sure the groove that's cut in the extractor is perfectly aligned with the cut in the slide. Doesn't take much to bind. Link to comment Share on other sites More sharing options...

Bakerjd Posted April 4, 2021 Share Posted April 4, 2021 I'm having a hard time believing they missed a step considering these are built/fit by hand. I also wonder why someone would replace good machined internals for other machined internals. But I have had my PM45 apart quite a few times and it goes back together just fine.

yigal Posted April 4, 2021 Share Posted April 4, 2021 There is a difference in diameter of FP between the 2 calibers 9mm and .45" and in some .40". And a small tip. The thin end goes in first. Link to comment Share on other sites More sharing options...

RGC Posted April 4, 2021 Author Share Posted April 4, 2021 UPDATE: Okay, so even the OEM FP would not install. I have DP extended for 9mm and a Limcat extended. All no go. I did have a couple of old SV's. I tried to insert all in reverse, just to see what the hang up was (inserting tip into breach face). EVERY one would only insert 3/16 or so. Leading me to believe there was a burr (and when I took it down for first time, the factory obviously got the FP installed but there may have been an issue pending but I never fired it). SO, I then installed the older SV, and tapped it in. The FP protruded from the FP hole now, but it was stuck. Tapped it back out. Suddenly all FP's are working again....So a burr it must have been (air blasted it so wasn't another foreign object i believe). First for me....

Also I've found that the extended FP sometimes are slightly too tight for the hole. I've had to check many of them in a drill and run some fine grit sand paper on the tip area to get them to go in/out smooth. Link to comment Share on other sites More sharing options...
Ignatz Posted April 6, 2021 Share Posted April 6, 2021 I went through the same thing with my wife's new PM9. About 10 minutes of WTF and then it went back together. Other than that firing pin issue, it works perfect. Link to comment Share on other sites More sharing options...
