Hi all, I recently bought a Glock 17, and have so far only shot the 115 grain roundnose type of bullets you find at Walmart. I'm still learning, so please bear with my simple questions! Can I safely shoot +p ammo in my all-stock G17? And what exactly does the +p designation mean? From what I've gleaned off the boards, it's a hotter load that results in increased muzzle velocity. Is that correct? Also, what are the advantages of the different bullet weights? For example, I want to order some hollow points from Midway, but they're all sold out of 115 grain ammo, so I'm thinking of buying 125 grain. What are the pros and cons of that, and is it even worth worrying about? Thanks for your help.
