Re: S&W .40 Sigma trigger mod
Rocketman, after checking, a couple more things to say...
1- In post # 24....per pic I show where to polish hammer areas on
TOP of pistol, that long flat arm that comes from trigger to hammer
assembly....you just polish INNER of that flat arm, as "some" folks
experienced some rub or grit there....in fact...if you look close at the
pic, right between arm and frame where one of my green lines goes...
you see the little black plastic frame runner that actually can rub this
"Some" even showed filing or removing enough of that plastic area so
that nothing can rub....if yours is tight, then do that..otherwise just
polish arm (inside / next to frame) very bright. I also grease a drop
right at that point each cleaning.
And, this "arm" is what you carefully move from pivot point of hammer when you have used a punch (at top rear of pistol) to remove the only pin
you need to remove sear/hammer assembly....but...the end of arm that
connects to trigger stays intact, so handle gently, when removing and
if polishing etc...
2- I would not ask for any to do anything that they feel uncomfortable
about. I am an EE and Microwave and Digital Engineer by trade, but with
much time in a machine shop. I am not a gunsmith, just a smith per my
own weapons if desired. I looked and studied much before I did anything to
my Sigma, I did not by any means do all I saw being done by others,and
have in fact passed on some things I have determined myself to do, that
I have not seen elsewhere.
I have simply passed on the simplest means I know for any that may benefit, keeping safety and reliability foremost. And as I said, 700 to 1000
rounds will almost do as much to trigger feel as anything I have suggested or done....except...
If you do nothing at all, except clean it...get a set of punches so you can
take the one top rear pin out, remove sear molding and hammer springs, and do grease and lube the sear cam or lobe where I showed. If not...
eventually yours will indeed have plastic scoring as in pic I showed from metal to plastic wear.
