G20 LWD slide-firing pin issue

[ThePunishr]

I've bugged a few people here already on my current project - I'm building a G20 upper for my G21. I have a new LWD G20 slide, and a Glock Upper Parts kit. I assembled everything (including the channel liner for the firing pin assembly that I originally forgot). I have not fired the upper yet as I'm still waiting for a barrel. I seem to have a n issue - on my G17 and G21 uppers, the firing pin does not move much unless you push the firing pin safety. On this slide, the firing pin moves quite freely. You still need to compress the assembly to remove the little door. I also find the extractor sits in the slide very deep. I know the G20 slide is thick, but my G21 and G17 exractors are flush with the side of the slide. Any ideas folks? Here's a couple of pics...

Are you sure you have the right spring bearing, I know they have 2 different types for the 45/10mm

+1 on the spring bearing. I see from the pics. that you're using the newer "LCI" type extractor. There is a difference in length between the 2 bearings & they MUST match the extractor used.

problem solved guys - I had my gunsmith look at it, and lo and behold, it has a 9mm firing pin!! I stripped my G21 upper and put that firing pin in - everything was fine. I had never bothered to measure the 2 pins together. Silly miss on my part, but all is well now.

Thanks for filling us in on the problem. I honestly never thought of that possibility; It's now mentally filed for future reference !

You WILL like the 10MM, the horsepower gain over a .45ACP is fantastic.
Accuracy isn't too shabby, either !
