P250, P320, P320 X-5, M17, & M18 Pistols
I've had my OLight Baldr Mini light/laser combo mounted on my P320C for a couple of months now, and I initially co-witnessed it w my irons at 10 yds to the point where it was pretty much "paint and shoot" 9's and 10's.
When I move in to 7 or out to 15 yds, I lose enough accuracy that I shoot...
