Trigger Pull



I recently bought a S&W Sigma .40 semi-auto pistol. The trugger pull is ridiculous on this thing. Is there any way to lighten the pull?

Absolutely! While it's not practical to try and put a great trigger pull on any of the Sigma's, they can be significantly improved without to much difficulty. Any significant reduction does require the use of a reduced power striker spring though, and theoretically could compromise reliability, but I haven't seen it.

The power of your striker spring in large part determines with how much force the striker will impact the primer. So a lighter spring = a lighter strike, and that has the potential to cause a misfire. Now I have really never seen this be an issue with this gun, but it could happen.
lets say for example that you had a hard primer... Or a dirty gummed up gun, or for whatever reason a primer that would have just gone off with lets say a 5# spring, but won't with a 4 pounder.
Just something to consider is all.

I can't thank you enough for the info. I had the trigger job done and it went down to roughly 8.5 pounds compared to the almost 13 before. The gun shoots like a dream now.

Thanks again!
