Trigger return spring

[CB3]

Don't mess with it.

Believing I might be able to shave a few more ounces off my TP9 trigger pull, I tweaked my trigger return spring by bending it a little so it would have less forward pressure on the trigger. I achieved that. And ruined the trigger action on the gun.

Without sufficient forward spring pressure on the trigger, it is slow to come forward after firing, and at times it did not have enough drive to reach reset, causing me to short stroke the trigger. Duh.

I have replaced it with a new one from the factory, and all is well again.

Learn from the mistakes of others.

Thanks for fessing up. It sounds like something I would try, appreciate the heads up.

Sometimes it's best to leave well enough alone, especially when one doesn't know what the end result will be.

[Bawanna]

Of course sometimes we don't know that we're well enough until we experiment. At least the that's the story I came up with for the many times I've been in this same spot.

Just thought I'd try something different this time:

Kind of like the old days when guys would back off the strain screw on their S&W revolvers to get a lighter DA trigger pull.

We had two guys, not one , show up for quals that were having misfires during the COF w/thier issue M10's. This was with factory service ammo.

After about a dozen misfires between the two of them, I knew exactly what they had done. They didn't know what they were doing but thought it was neat to have a lighter DA trigger pull.

No misfires after the strain screws were screwed back to their original position.

Their actions could of had deadly results on the street had they not come to qualify first.!!!

Maybe I have an unusual PM9 or an excellent copy because the action on my pistol is so nice, I wouldn't consider changing it in any way.

A lesson I learned the hard way ... actually learned it more than once, but I'm a slow learner ... "If it ain't broke, don't fix it!" And a corollary to that lesson is that you should be very careful about listening to what the guys down at the pool hall say is a good thing to do! That's maybe worse than taking a dare ...

For those wanting to lighten / smooth the trigger pull, I've developed a modification that accomplishes this. I have a couple threads going about trigger mods, one in the k forum and one in the tech forum. Steve
