the sigma is simple and it will go bang but that is as far as it goes. the trigger pull is absolutly horrible and the accuracy of my nine and my roommates fourty both left something to be desired this gun is nowhere near a glock or a sig but it is light years ahead of a hipoint. there is give and take but mine went down the road quickly to be replaced by a g17 and im not sorry to see it go but for the money i should not have expected the performance i expected. my vote is save your money and buy a glock or an xd
