Please dont buddy.. This is not an opinion. I owned same gun for 2 years. complete piece of shit.
I traded it and a bersa 380 for a nib glock 19 rtf2.. and man am I happy now.
the sigma had nothing but problems the 1st 200rds or so.. the mag falls out when shooting..I called s&w and they sent me a mag release for a .40.
I called and told them and the douche bag had the nerve to tell me they are the same..lol.. Its clearly marked 9mm on the bottom of it once you remove it.
I finally got the correct one and it still did nothing to help it..
then on a hot day, the trigger would not work.. I was pulling it in and in. Nothing.. took it home in the a/c for a while and it dry fires fine.. lay in the sun for and hour and it wont.
plastic inside gets so soft it wont even function..
I could go on forever.. hope this helps you decide..
save that 200 for something else.. I learned my lesson
