I’ve been using red dot equipped duty/carry pistols since 2009. This is at the beginning of their use for duty. Between myself and teammates I have seen at least 50,000 rounds put on JP/Tasco/Shield/Trijicon/etc mini’s, Trijicon RMR and Type 2, Leupold DP and Pro, MRDS, Burris, Vortex, etc, etc. All used heavily on duty, carry, and competition pistols under all conditions. From -20 degrees and in 4 feet of snow, to 140 degrees and desert.
The only ones I would mount and use are-
Trijicon RMR 06 Type 2
Leupold Delta Point Pro.
Thanks for your insight. Have you had a chance to evaluate the Sig P320 RX as part of your testing?
