its just straight up unnecessary
lets look at your reasons for op to purchase a glock:
Small enough to conceal: correct, on a daily basis? no.
large enough to get a firm positive grip on: this is just a pretty dumb statement
great magazine capacity: op lives in california and its illegal to have a magazine that holds more than 10 rounds
cheap, readily available: .22 caliber ammo is one of the most manufactured ammo, also one of the cheapest
last but not least, it is a Glock: who doesnt love a glock, ill give you this one
can already see where this thread will end up though. OP gets a block, ends up using it for home protection, buys smaller gun to carry
