i am looking to buy a glock chambered in .45acp. i was seriously considering a Glock 30sf but now i am wondering if i should opt for the 30s model. i understand it has a slimmer slide, but i am wondering if it performs the same. i have heard conflicting reports about recoil ect. i was wondering if there is anyone here that might be able to shed some light on the subject to help me better define these two guns. thanks.
