IDPA match shooting my 9 mm Glock 17 at the Hibbing Minnesota range stage 4

I took my gen 3 glock 17 to the Hibbing, MN shooting range to shoot the IDPA course they had setup. In this stage we were shooting very small metal targets that react when you hit them while moving. All shooting was supposed to be while moving other than for the last 4 targets, which was quite challenging. I ended up getting all but the last 2 because I only had 30 rounds of ammo. "3 mags and other guys were using 4 or 5 mags."
