Cutting the spring will affect reliability, you are right.
I did take the gun a part and polished all the parts involved in the trigger pull, so the trigger will probably not get any smoother. It is perfectly smooth now! I just would like it a little bit lighter.
While we are discussing "trigger jobs" and polishing......I thought I would add this note of caution about some facts that many people don't realize.
Many trigger componets - things like sears - are only "surface hardened"
What this means to us is ............... the case hardened portion of the sear is only a tiny few thousandths of an inch deep !! So if you "polish" these parts any deeper than that......... the parts will start to wear dangerously fast.
I have seen many a trigger group ruined by over polishing of the contact surface points. Gunsmiths are aware of this tiny margin in which they have to work.......... the lay person is sometimes ignorant to these facts.
I am not suggesting that P99 &1/2 has done anything wrong as I am sure he used the appropriate caution......but for those folks that didn't know ..............
Well, if it all comes to number of shots fired through a gun to reduce trigger pull, than what's wrong with leaving the gun (P99) partially cocked for a while to let the striker spring compress a little?
Nothing - but I really don't think that would make much difference - The # of shot thing that makes it smooth out over time is because the parts tend to polish themselves as they rub together on their own while firing. U can try to leave itprecocked for a while and see if it helps - that's never come up here before. But, I don't know if it really would matter
