It's time to buy a new carry gun. I've decided on a Glock, cause they work for me, there is no changing my mind. I want as much power in a small package as I can get, so should I get a 36 or 27? First, this gun is going to be carried everyday, IWB. Second, ammo cost do not matter, nor does accuracy over about 15yds. I don't plan on getting in gun fights across parking lots and whatnot. Third, it will not be a HD gun, I have a shotgun and full size handgun for that. I'm leaning towards the .40, not cause I like the round, but cause it has a little advantage (I'll take all I can get) over 9mm and has higher capacity. I am considering the .45 cause I love .45s and it has more power. What's your opinion and WHY? the gun will maybe see 100rds a year. I can shoot a 27 and a 36 just fine, I don't need to "get good" with it.
