Its another M Forgery lol. I dont care for the first model Sig came out with the Sig 556 models. This model in my opinion is much better. The one I handled had a smooth trigger on it. I dont know of any one who has one that has shot it to give you any statements about accuracy. I dont know if they are cast or forged, or who they get thier parts from.
I've only shot about 80 rounds through an almost brand new one so it hadn't even had time to "break in". Worked flawlessly and I ran 3 types of ammo through it including 5 rounds of that Wolff steel cased crap.
Ran like a machine. Case in point...I'm buying my own M&P and will accesorize as needed.
