glock 27 not bad, good gun but i found the lack of a full grip an issue when pulling and shooting. and lighter weight with a compression round (ie sw40 or sg 357 magnum) very snappy.
look into the g23 before buying the 40 cal 27, i am liking the full grip and still able to conceal carry. its 12 +1 loaded. longer barrel is better accuracy with out loosing councealability(sp).
