What is everyones thought on this? Would you feel "underpowered" with 8+1 rounds of 9mm in your go to gun? I know people use 1911's as their goto guns which are running single stack mags but most people give it the pass just because it's a 45......... and it's the 1911.

So should a single stack 9mm be solely for CCW use or do you think it's sufficient for an all purpose, defensive handgun? I definitely prefer the way a single stack handgun handles over a double stack but I'm questioning whether or not it'll be a handicap in a fantasy gunfight situation. Thoughts?
