We all like to use our guns.

That's not the same as being good with all of them.

Unless you spend all your time at the range, you will give up significant speed and accuracy 'rotating' your handguns.

Speed and accuracy are pretty important in sd situations.

Pick one or two and stick with them.

I usually EDC a Colt Commander except in the woods, when I carry a Colt 1911.

If I can't use that because of dress requirements, I drop a M 38 in my pocket.

As a result, my practice is manageable: 2/3 with a Colt 1911, 1/3 with a M 38.

That's doable so I don't have to devide my time between a Glock, a M 15, a M 19 or any of the other handguns in the safe.
