I'm finally just a few weeks away from picking up a Glock 19. I know that it will accept 15, 17, 19, & 33 round magazines. I'll be using the 15 round magazine in the gun while carrying since that is what fits flush (obviously), but I'm thinking about using 17 or 19 round mags as my backups/spares. Anyone do this? Does anyone have a problem concealing two 17 or 19 round magazines?
Are there any reasons not to carry larger-than-'standard' magazines? I hope / assume I'm never going to need to fire one round, let alone 2-3 magazines full, but since I'm preparing for the unknown by carrying in the first place, I figure I may as well carry as many rounds as is practical to carry & conceal.
I don't want this to be a thread on "how much do you carry" or "how many rounds do you think you'll need" - I've read those threads & have my own opinions on the answers to both. I'm really interested in knowing if anyone has any problems actually concealing 17/19 round mags, or if there are any good reasons to not carry larger-than-15 round mags.
