250 rounds in pouring rain:
Started with my CZ P-07 from concealment under winter clothing. In honor of the excellent shooting ability of Mr. Wilson, I was working on head shots on a Metric target at 12 yards. The raingear and heavy sweater slowed me down, but the times weren't as bad as it felt. Average was around 1.7s. When the rain let up, I shot with just a heavy sweater: average ~1.4s for 26 hits, and 2 misses. Two fouled draws brought my time to around 2.0s each.
It was raining so hard that I didn't switch to my USPSA Production rig, and completed the rest of the practice with my carry gun.
