I too carried a 1911 tuned for reliability on duty. I was hired on another department that used Glock 22's and bought one to become proficient before I had to trust my life to it.
Took both to in indoor range and dumped the usual 500 rounds... 250 through each.
Targets ranged from 5' to 25 yards. Slow precision aimed fire to timed stress shoots with multiple mag changes.
Long story short my groups in almost all targets were 1/2 the size using a Glock...and it didn't matter what model or caliber. I shot them all the same from the 380 through the 10mm or 45acp.
Soon after that faithful day I sold all of my 1911's and ended up with about a dozen glock in differrent calibers and sizes.
Today I have only one Glock... and no 1911's.
G20 10mm and it is my go to gun.... but I wish I kept 2 and never sold the G26 9mm for it's concealability.
I no longer work where I need to potentially defend my life every day so the handgun inventory has gone waaay down.
