I think they would both be good....it really comes to personal preference....I just stepped up to a 45 from a 380....the 45's just a little thicker:clap....but holds 10 instead of 7....can't wait to shoot it
I carry the 27 but as soon as i find a keltec or lcp im buying one. I had one a miss it. When youhave a gun that is to big or bulky to carry what good is it sitting at home or in the truck. You should check out the keltec or lcp, very light, easy to carry. I used to forget i had it on me. Not with this big ass glock. Even though the 27 is small after carring that keltec the glock is a tank.
