re: What Personal Defense Weapon (think 9mm SMG) is everyone using?

I have a Stribog a little bit big
Beretta a good gun but.... and a Sig MCX. It's just about perfect.

I say it every time this conversation comes up

SHADOW SYSTEMS CR920 Combat

If you haven't shot a SS yet you need to go shoot one. Silky smooth and you don't have the flaws that the SIGs have.
Say what you want about a SIG. I have a CSSO license and I spend time on the range every year with guys carrying multiple guns. The SIGs DO NOT perform like the SS and Glocks do.
Smith and Wesson's seem to do ok. Springfield Arms makes a solid unit as well.
I have a .40 SA for home defense. One of the guys on our CSSO team carries a Hellcat. Nice weapon.

But I am not a SIG fan at all. Seen some accidents and near accidents with them that back up the stories I've heard.
