Just curious...

Does anyone load a round in the chamber and then top off the mag?

I never have. These days I'm carrying either the Glock 19 or 30S with two spare mags. I just load a round and when I'm back home or done for the day I eject the round and back in the mag it goes.

Matter of fact, I've never done +1 even in my hunting rifles....

It ain't what you don't know that makes you an idiot...it's what you know for certain, that just ain't so...

Most people don't want to believe the truth~they want the truth to be what they believe.

Stupidity has no average...
