well personally i would send it in i have had my sigma for over a year now and put approx 1000 rounds down range with it without issue so my guess is you just got unlucky and got a bad striker somehow
Didn't know anything was wrong with them.Been shooting them for years,(accurately also).
There is no striker issue with the sigmas. You may have just got a bad one. I will say that I have seen some broken striker stories lately and they were all from improperly field stripping the guns. If you pull the slide back too far when you are attempting to strip the gun and you cock it and then pull the trigger, which propels the slide forward by the force of the striker spring and the striker, this can break the striker. Even one of the trigger mod videos on you tube shows the gun being field stripped this way, which might make you think it is ok, but it is NOT ok and should be avoided.
I'm going to have to disagree with you on this.
1. you don't have to pull the trigger to field strip the sigma. Like the Glock, you must dry fire to decock the weapon, rack the slide back an 1/8 of an inch and then, pull the slide latches down, and then remove the slide.
2. This gun is very much like a Glock, you must dry fire the weapon to decock. It should not hurt it at all.
Ummmmm.... How do you dry fire the weapon if you don't pull the trigger?! Just sayin!!
Not sure what you are disagreeing with, because we are saying the same thing in different words. You must dry fire to decock, I agree, but then when you are racking the slide back an 1/8 in and pulling the slide latches down, if you happen to go a little too far and the gun cocks and then you pull the trigger again, it will actually propel the slide forward from the spring tension on the striker, which can break it. I could have worded it better, but this is what I meant.
S&W says different, and I don't do it as I believe S&W, and I have read about this happening 3 or 4 times recently.
