I have a question about the trigger spacer on my PM45. Yesterday I replaced my trigger on my Black Diamond PM45 with a stainless one. I also replaced the trigger spring, spacer, and trigger pin. The original spacer was metal, while the replacement directly from Kahr was plastic. After replacing the parts, I dried fired it a few times. AMAZING DIFFERENCE!! There was drag felt along where the spacer and trigger bar met when I fired it with the metal spacer in, but once I did so with the plastic spacer in, the drag was gone. Even the reset was more positive with the plastic spacer in. My question is what is the life of the plastic spacer? Definitely gonna order a few more to have as backup. Just curious on how long they last. And by the way, swapping trigger was not difficult by any means, and I'm no gunsmith. Pin came right out with punch. ( I used a spare grip holding tool from an M&P 40 and it worked GREAT, as well as a rubber mallet.) Thanks for reading!!

You could try the tootsie-roll pop experiment: lick it three times, then bite it and see if it breaks.

I don't recall hearing anyone here ever replacing a PM45 trigger. It's comforting to hear you say it's not that difficult. I didn't foresee the need to ever do so but if it ever comes up maybe, just maybe I got a chance of getting it done.
I had no clue there were metal and plastic spacers either. Wonder which one is in mine?

I changed the trigger as well as the slide stop to stainless just for the look. The Black Diamond finish on mine isn't that great, but its holding up. There were no problems with anything. I wasn't aware of the original spacer being metal until I removed it, and Kahr sent me a plastic replacement. Read here on the forum that some are metal or plastic. Again, so far I am liking the plastic spacer due to the way the trigger feels now. Night and day difference.

You mentioned replacing the spring and pin as well, I wonder if it was a joint improvement or solely the spacers.
It does make sense that the spacers would be a big contributor.
Seems like metal on metal would get better and better, slipperier, where the plastic wouldn't as much but maybe it's better from the get go and stays that way. Not a lot of pressure and wear I wouldn't think.
Whatever it works good and that's the answer we always look for.

You would think that with metal on metal it would be better, but I could feel the rubbing when I pulled the trigger. Could also see it when pistol was field stripped. Again, there wasn't any problem with the trigger, did it because I liked the way the stainless looked with the blued parts. I figured that since I was changing trigger, I'd change the "guts" also. The rubbing I had at the trigger bar/ spacer is no longer there. Also the reset is more positive, as the trigger has a very audible "click" upon reset. My understanding from reading is that Kahr went to plastic because of self lubricating properties so to speak. And one other thing, you have to make sure flat part of spacer rests correctly against trigger where it sits to get it lined up correctly.
