I carry a Glock 36 in .45 ACP with 6 rounds. That's it. I use to carry two additional magazines with 6 rounds each but that got cumbersome. I figure if I need more than those 6 rounds I will be running away anyway. Besides the G36 for carry here in Wisconsin I occasionally carry a 5 shot model 85 Taurus in .38 Special. No extra rounds for it either when I do. I always hope I never have to use it and if I do my aim will be true.
