WOW!!! Unreal, and lucky...given the situation of course
Ouch .. very luck lady !! One reason I don't alter any of mine .. don't have the knowledge to safely do anything other then grips .. all my pistols came new in box from a distributor or FFL ..Some of the narrative raises questions in my mind about what really happened and how. Regardless, this is why I feel better buying BNIB. I admittedly don't have enough in depth knowledge to strip down a firearm at purchase and say this has been altered or not in a good way, safe way, or bad way. Hope she recovers fully though.
Okay, I agree with you. If one is not knowledgeable, mechanically adept, and does not have the right fixtures and tooling, it is wise to follow your advice. If that be the case you can stick with stock or send it to someone like TheSigArmorer if you would like it much better than stock.And that's why, as much as I love tinkering, I don't ever mess around with sear geometry. Internal polish / lightened springs is the most I'll do. I don't even mess with over-travel screws after experiencing the USP's Match trigger kit. It literally takes two thou to go from a functioning gun to a paperweight... Or worse. That's also why I stay away from the GG P-SAIT. The whole function rests on just the strength of the Loctite.
