I put a hundred rounds thru the G27 at the range not too long ago and it fits fine in my hand. Having the option of keeping it tiny and the option of adding the larger magazines (G22/G23) is what really sold me on the subcompact Glocks. Shit, even the 33rd magazine will fit in it. The Glock system is pretty dialed. Going with the .40 also leaves the option of swapping out a .357, 9mm or 10mm barrel in turn making it three guns in one. And taking that and pairing it with the longer mags that makes it even more in one. I like the ability of concealment with ease even though getting a CCW is going to be impossible for me due to location.
