Xander Posted November 25, 2012 Share Posted November 25, 2012 Anybody here changed their hammer, fp and trs to the lighter ones from hkparts.net. What noticeable difference/improvements? TIA Link to comment Share on other sites More sharing options...
424D57 Posted November 26, 2012 Share Posted November 26, 2012 What model and variant do you have? If memory serves, USPs and USPcs in V1 already have the light everything. I suspect the same is true for V3 P series pistols as well. If you're already into LEM, going to light will depend greatly on where you started. -424D57 Link to comment Share on other sites More sharing options...
Xander Posted November 27, 2012 Author Share Posted November 27, 2012 P30L V3, thanks Link to comment Share on other sites More sharing options...
Steven420 Posted December 24, 2012 Share Posted December 24, 2012 v3 already has light everything except the fpbs or firing pin block spring. switch to the lighter fpbs to reduce single action trigger pull by 1-1.5 lbs. swapping the 14lb hammer spring with a 12lb spring will drop your double action pull by the same amount. I run a light fpbs and a 10lb hammer spring. hkparts has the fpbs, and wolff springs has the hammer springs for p series pistols. Link to comment Share on other sites More sharing options...

Btw, what is the trigger pull weight in DA and SA with your set-up? Thanks! Edited December 29, 2012 by Xander Link to comment Share on other sites More sharing options...
Steven420 Posted December 30, 2012 Share Posted December 30, 2012 (edited) factory is 11.4lb DA 4.5lb SA. Mine is around 10ishlb DA 3.75-4lb SA with the light fpbs and a wolf 12lb hammer spring. I had some light primer strikes with the 10lb hammer spring and winchester primers. All the federals popped with the 10lb spring though...

KJFpdx Posted September 26, 2014 Share Posted September 26, 2014 I had some light primer strikes with the 10lb hammer spring and winchester primers. All the federals popped with the 10lb spring though.. === Reviving this thread. What does "light primer strikes" mean? As in, the new lighter hammer strike was not sufficient to ignite the primer? As a new-ish shooter, this terminology is new to me. Thanks. Link to comment Share on other sites More sharing options...
Trader Posted September 26, 2014 Share Posted September 26, 2014 " Light primer strike " fails to ignite the primer resulting in a misfire. I just had a couple shooting Hornaday Critical Defense on DA with USP .45 / 10lb hammer spring. Federal, CCI and Tula primers have all worked first time.
