My department's issued handgun is a G32. It seems to be a little more accurate than my personal Glocks, C21, G23 and about the same as my G30. I had a G27 for a BUG that I liked a lot until I stumbled onto a G33 at a price to good to pass up. When I shot the two side by side at 25 yards the G33 was way more accurate than the G27 and it was the equal to my G30 and the department G32. The G27 is gone. I doubt my experience is the rule, but I'm very impressed with my G33 / 357 sig's accuracy. The issued ammo is Golden Saber 125 gr. Training ammo is whatever is the cheapest, all of it shoots well in the glocks.
