I first started carrying 1911's in the mid 60's. Locked and cocked. When I got out of the Corps in the mid 70's I went back to my revolvers. I first learned to shoot with revolvers in the late 50's.
I carried various revolvers for years.
In the early 90's I began to carry a SIG P-228, DA/SA of course. AS a a long time revolver guy, the DA/SA trigger wasn't a problem. If I was going to miss on the first double, it would be on the SA, not the DA.
Because of my arthritis I have returned to the 1911, in 2000. I have always carried the 1911 locked and cocked.
One of my problems is when ever I changed carry weapon, I would change what kind of weapon I compete with. Only one action type allowed at any time for fighting and competition, training and serious practice. I shoot any type of my guns when shooting for grins and giggles.
I always have a second weapon either Identical or very similar to my carry weapon. During my revolver days, My competition weapon was a S&W of course model 14. My carry weapons were either model 19's, 10's,13's or later model 66's. My final carry revolver was a model 66 3" barrel with night sights.
I went to the SIG 228 and would compete with either the backup SIG 228 or my SIG 226.
When I switched to carrying a 1911 again, I started competing with various 1911's I either had already or new ones I bought.
My present carry weapon is a Colt Gunsite Pistol, government model. I have two. I either shoot the CGP #2 or one of my two Kimber Warriors for most training and competitions. I also have a series I Kimber Gold Combat Stainless I sometimes shoot for IDPA.
The concept is if I must go for my weapon, either at home in a Home Defense situation, or while out and about while CCWing, I know the action without thinking. No adaptation, no "which gun am I carrying"? It must be subconscious, instinctual and automatic. How I draw or grab and shoot a 1911 automatically turns the safety to off, or the gun to on, with no thought given.
The other point is to have a second weapon ready to go if #1 is taken out for some reason. Maintenance, broken, stolen, being held as evidence, etc... But make sure it is the same, or similar enough in function and controls that there is no time wasted on remembering the weapon you are carrying.
Good luck to all.
