like austinrealtor said you can change the grip on a G27 with extensions on the magazines and you can even use a G23 magazine in a G27 with a spacer.

I like the modular concept. You can always make a small gun bigger. A G23 or a G32(357sig) barrel will work in a G27, it just sticks out of the front of the slide 1/2".
If you have a concealability situation you can carry the G27 with a stock 9 round mag. I carry a G33 with a 13 round G32 magazine and the spacer. I have a stock 9 round mag and another one with a + one extension. I bought a G23 barrel if I want to use 40 S&W. I carry a 15 round G31 magazine for a spare. Glocks and leggos, you gotta love um! I bought a G31(full size 357sig) for a house gun. I chopped the grip so it will take the G32 mags since I have a number of them.
