Two questionable ideas in a single concept. I'm worn out beating the industry-driven red-dot-for-carry horse. Few are willing to listen to experience. Most prefer to buy a piece of cool magic equipment rather than do hard things, like regular well-informed shooting practice with simple reliable systems.
- (Just because I can't help myself, my former colleague was at a training session last week at our previous agency, for the RDS-equipped G19 that are now being handed out to anyone that wants one. One shooter dropped his pistol on the floor and the Trijicon RMR lens cracked. No one ever drops a gun in a fight, right?)
I echo the sentiments of the other LEOs that have commented on the very poor idea of small of the back carry, especially in terms of getting knocked down or falling. Will also add:
1. Your ability to protect your firearm from being taken from you is severely compromised in that position. Crook spots your gun in public and if he wants it, he's taking it.
2. Your ability to draw and holster the firearm quickly and safely in that position is also severely compromised.
Also,the idea that you are going to tell the robber, "ok here's my wallet", and then come out shooting, contains a number of unrealistic assumptions in terms of criminal behavior.
