Problem with Short Reset Trigger??

There may be a potential problem with some Classic P-Series pistols. If you're reading this, please consider doing the simple check below.

On two P229's with short reset trigger, I've found minor damage to the firing pin block (FPB ) plunger and firing pin upon disassembly. This was caused by the safety lever not pushing the FPB plunger up far enough to completely clear the firing pin, so when struck the firing pin slightly impacts the FPB, moving it out of the way with the impact to continue forward to ignite the primer. Of course this impact takes energy away from the firing pin and could potentially cause FTF.

The check: Insure gun is unloaded. Cock hammer. Using a Q-tip or suitable stick, pen or punch, push forward on rear of firing pin, it should go forward a short distance. Pull trigger slowly to rear until it stages against sear. Ideally, FP should be unblocked at or before this point. When it's unblocked it will move further forward, and should do so smoothly, not hitting the FPB plunger. If it does not unblock at sear staging, then hold hammer back so it will not fall and continue pushing on the FP, while slowly pulling trigger back until sear just releases hammer - if FP is unblocked at this point, it's on the ragged edge so to speak, but could still be okay but with no tolerance for further wear IF, when you push and release FP it moves smoothly, not hitting the FPB plunger.

Please post results in this thread.

I already know I'm not the only one who's noticed this problem, I'm copying the following from another thread where Ipesenson says:

From what I am hearing above, it is similar to my problem: as the safety wears, the FPB starts interfering with the movement of the firing pin producing light strikes in some types of ammunition. I ordered a new one, but it's very possible that it will need to be replaced after a couple thousand rounds. Unfortunately I do not have access to tools to manufacture my own safety lever, unlike bumper, so cannot customize. Maybe bumper can start a business creating better SRT safeties
In the other thread, in "gunsmithing" I post a fix I've done for this problem, making an improved safety lever, post #7 in this thread: Classic P- Firing pin block safety lever

How many hands does it require to do this?

Well, it does help to be coorjudgeuminated.

Didn't the earlier SRT kits contain a safety lever with a shorter leg?

I think this issue was addressed by Sig a while back and the never kits contain a lever with the longer leg.

Glad my 226 checked out OK with the first step.

Couldn't figure out how to do the "then hold hammer back so it will not fall and continue pushing on the FP, while slowly pulling trigger back until sear just releases hammer"

The new longer leg (#9) safety lever was introduced to fix a different problem. The orginal short leg could get hung up on the top of the trigger bar, keeping it down and causing a "long reset", and that could potentially cause short stroking the trigger (bad in a gun fight). In all cases I'm aware of, and in my testing, the reset would occur after allowing the trigger to go most of the way forward, so the gun would not be taken completely out of action due to this failure mode. It also tended to be quite intermittent, not happening with regularity. With the new longer leg, the TB cannot get caught under the leg as the frame won't let the TB go that low (the TB, during recoil, could be driven down by the reset tab much lower than would occur when just manually operating the slide - not something one would think about).

The "new" potential problem is unrelated to lower leg length, and was not addressed by SIG's safety lever change.

Yeah, helps to be an orangutan. I have big hands, so can pull trigger and hold hammer back with one hand.
