I have a MTAC Minotaur Slide model. My EDC is a G23. (Same exact gun in 40 cal) I got the slide model because it works just as well with any 9mm, 40 cal or 357 sig that Glock makes.
I have also seen lots of good things about the Crossbred Supertuck.
Either one will work very well for the G32. Oh, congrats on the 32.. great SD gun. I have a G35 with a 357 Sig conversion barrel for HD.
