I'm looking to put one of these on my Glock 19 MOS for CCW and range fun. I'm torn. I'm a buy once, cry once guy, but the price on the RMR is stout. Anyone with experience with both of these that can tell me what I'll be missing out on if I go with the Venom? My head is telling me the Venom will more than meet my needs but my heart, which coincidentally controls my wallet all too often, is telling me to go all out for the Trijicon.
