Yesterday I was working on my 1911 pistols, tweaking some newly installed sear springs slightly to improve trigger pull let off. My Springfield Armoury and EEA Witness Custom .45 were fairly straightforward but my Kimber Stainless Target II 9mm was a different story.
I was able to get a reasonable and crisp trigger let off but it is definately heavier than my .45’s by at least 1.5 Ib, maybe a it more. I reached the point where the spring was too light and the hammer started to occasionally follow the slide down when released from fully locked with the slide lever, so I bent the sear spring leaf forward again until it stopped doing so.
All three pistols have had light internal polishing with the hammer hooks honed to .020” height. I do not want to take the hooks down any further as I feel that would make the pistol unsafe.
The Kimber has the Series 80 firing pin block whereas the others are Series 70. I have heard that removing the firing pin block will lighten the trigger noticibly.
I can obtain the replacement spacer locally, however when I polished up the sear replacing it in the frame with the firing pin block actuator was not as straightforward as installing the Series 70 sear/disconnector assembly is. I can’t now recall just how I installed it (lining up the sear, disconnector and firing pin block holes correctly). I do know it took me a long time.
So before I go and order in the spacer is removing the Series 80 firing pin block worth it and will it improve the trigger to near that of my Series 70 pistols?
