Let me start out by saying that I hate shooting Glocks.
They suck to shoot, there ugly as sin, and they have the ergonomics of a brick.
But get a Glock. My next handgun will most likely be one.
High capacity mags (even standard ones) means you can carry quite a bit of ammo very conveniently, the parts are highly interchangeable between same-size models, replacement parts are easy to find, most aftermarket parts are a true drop-in fit (none of the custom fitting as needed with 1911s, as much as I love them), they're CHEAP which means A) more money on ammo, B) less upset you'll be about abusing it, C) less upset you'll be about something happening to it (stolen, taken for evidence, etc.), etc.
Hope this helps
