I see that many people here carry various kinds of handguns. I am curious how it works out when switching off between a DAO and a SA with a safety and a DA/SA. I've carried a Glock for most of the 21 years I've been an officer and have 100's of thousands of draws and shots on that platform. I used to carry an off-duty that had a safety and was a SA/DA because it was more convenient. I qualified with them and shot them quite often so I was comfortable carrying them. About 13 years ago I had to draw and fire my Taser. The Taser has a manual safety that turns on the device. I no time to think, I just drew and fired. But it didn't fire because under stress, I didn't activate the safety thus I fumbled. I have so many reps on my Glock/DAO platform that it was my "go to" under stress even though I practiced with other safety platforms and my Taser. I still carry my Taser but I swore off any platforms that require a safety. I just have too many reps on my duty platform to feel safe that I could operate it under stress. My off-duty Gen 5 G19 is IDENTICAL to my to my duty G17M in all practical ways. I even make sure I use the same night sights. I do own a S&W .38 for back-up that I can point/shoot if need be I don't really carry it off-duty since a speed reload under stress might be quit difficult for me. My word of caution (just I tell recruits) be careful carrying something too different to what you typically train with because under stress, it might take valuable seconds to get it working. time you might not have. Just my .02.
Right now, the main EDC guns are a G23, a P10C or a G30sf for this ^^^^ reason. All get shot regularly and all have the same operating parameters. I still love 1911s, but just don't carry them other than a USGI 1911 around the house on Veteran's Day, Memorial Day, 9/11, Dec 7th and Independence Day.
As a bonus, none of the normal carry guns would be missed much or hard to replace should any of them end up in an evidence locker.
