i.am new to this forum and new to hand guns. my ?'s are what are the differences BETWEEN THE CARRY .45acp AND THE REST OF THE SIG .45acp GUNS? also is $671 a good deal for this gun new? also is it good to put hogue grips on this wepon? and also how does this gun compare to the S&W, GLOCK, KIMBER, and the FNH .45acp wepons... sorry if am asking to many ?'s but i have a need to learn the curve. and make sure i made the right choice thank's Nick FLA...
