Hmmm...the sear was out-of-spec. That's bad. I wonder if that is a "common" problem...like they have a bad run.
Not to disparage any manufacturer, but one theory being floated around:
Gun and ammo manufacturers are possibly trying too hard to make up for the surge in demand for their products over the last year. Anytime you try to step up a manufacturing process there is a risk that quality, quality control, could suffer.
That shared, I'm not in a position to judge whether Sig, Ruger, XD, Glock or S&W (the most popular micro 9 makers) are having more or less problems than 18 months ago. Currently I'm on Sigtalk daily just because of my problem. Those who participate in other forums might comment on how things seem with other manufacturers. Haven't noticed any particular uptick in complaints on general forums (like THR).
Sig made good and so far it's holding. Obviously a meetup where everyone is shooting the same 2 models of gun there will be a lot of stories swapped. I'll share.
ON A SIDE NOTE: I'm amazed at how many failures I see at competitions. I might start keeping count. .22lr and PCCs seem to be the guns with the most problems, but I see shooters who due to ammo or gun have difficulties far beyond my tolerance. I think in the past year I've had 2 misfires while shooting over 50 competitions. I see people with 3, 4, 5 or more failures in one stage. It tells me that a) they're not testing and practicing very much. b) They possibly need to select better equipment and ammo.
I don't think I'm overly prideful, but I don't want to stand in front of my squad and have an equipment failure. I had it happen, years ago, but not again. Going to the line confident your gear works is part of the game. Same goes for EDC. Leaving the house knowing that you can DEPEND on your gear to save your life is crucial, in my opinion.
