I keep the mag in the gun and my 2 extras fully loaded with +1 in the chamber. They were made to hold that many, and i havent had any problems out of them except with hornaday JHP thats why I personally dont use them the first round would get hung up on the mag. Federal, Corbon, and DPX (JHP for all of those) never had that problem with them. But I would tell do what you feel comfortable doing, if you want to carry a few rounds less go ahead if you want to stay fully loaded by all means do which eva makes you happy.
and end rambling ;D
