    Hi. I'm new here. First post. Discovered the forum via a search. I'm the proud new owner of a Sig P938. (Big grin...my smilies don't seem to work.)

    One of the posters here said his P938, which started out with a trigger pull of about 9 lbs, worked its way down to about 5.75 lbs after 500 rounds. Mine feels like about 9 lbs., too, and I would prefer a lesser effort required. Since this is going to be my CC pistol, maybe not as light as my Kimber, or my Defender (yes, I like 1911s), but lighter than it is now. My question is this - can this 'wearing' of the trigger be done by dry-firing 500 times, just as it could by firing 500 rounds? i.e. Does the firing of a round affect trigger wear any differently?

    Thanks for your input.

    Yes, dry-firing will polish & burnish the trigger parts as well as firing it.

    Use snap-caps.

    Snap caps will do what? Protect the firing pin?

    dryfire with snap caps will do most of that self-polishing

    protect firing pin and the front of the FP tunnel and/or FP stop from taking the beating that is normally applied to the primer.

    Also they tend to be brightly colored and NOT live ammo.

    Dry firing 500+ times would be considerably easier without the snap caps ejecting...I think I have about 3 snap caps. Maybe I could carve a notch in one of them, so it won't be caught by the ejector, and then rotate it to get it out. Anyone ever tried that?

    or just reset the hammer by hand

    or don't rack the slide as far

    OK. Thanks for the ideas. Oops, my snap caps are .45s. I'll have to go get some.

    Yeah that's one thing I can't do with my striker-fired pistols, is dry fire repeatedly. DA, just pull the trigger. SA, hammer back and pull.

    Not all DAs can be repeatedly dry fired. The Ruger LC9, for example, needs to be recocked by racking the slide after each trigger pull.

    Store was out of 9mm, but I got some .380 instead. That should work. Bet my thumb will be sore after a while.

    (Hope there's no Executive Order tomorrow, making dry-firing illegal.) ;-)

    True, Lemmy, but it's also not a true double-action. It is half-cocked by racking the slide.

    Well, my thumb is sore, but the trigger feels better to me. Is there some way/place to measure the pull, without buying something? Maybe a good fish scale at the sporting goods store? Hmmmm, public place. Any other ideas?
