Here is my list of RDS equipped pistols:
Gen 4 G22 (Stormlake 9MM barrel) with Aimpoint H1 with Unity Tactical Mount milled by Mark Housel at L&M Precision
Gen 4 G19 (USA build - unicorn series
) with a RM06. Milled by Zev. Bought from Aaron Cowen of Sage Dyanamics
Caspian double stack 1911 9mm with a RM08 milled and tuned by Mark Housel at L&M Precision
Para Tactical double stack 1911 45 ACP with a Deltapoint milled and tuned by Mark Housel at L&M Precision
Kimber TLE/RL II 1911 (yeah I know Kimber sucks blah blah blah) with a Jpoint
The Glocks are my main carry guns. The 1911s are reliable but just too heavy, but a fun to shoot and train with.
My obsession with RDS began with an M&P CORE (since sold). I bought because of my crappy 44 year old eyes (insert sob story here).
Long and short of it:
Training with red dots have actually improved my iron sight shooting because it trained my eyes to both stay open.
Precision beyond 15 yards is not a guessing game as it is with iron sights that cover a bulls eye at that range.
The sight picture is now threat oriented not front sight oriented.
Be Good. Stay Safe.
