It is kind of a glock copy. Matter of fact they had to pay a disclosed amount to flock and change there trigger design just to be able to keep making them. I don't really like how most flocks work bit hearthere really good. But my sigma I realy don't have any complaints about. If you have any reasons why you dislike them besides looks id love to hear them.
I have the sigma in 9mm it's - good cheap gun. Now I did have to send it in on warrenty, i had fte every few rounds but don't remember what they fix. now it shoots with out a flaw. Eats anything I give her. I almost sold it before I sent it in but now I'll keep her. Not to mention she was my first. .. Hard to let go
