First off, I agree with Brian W......buy 'em all!!!!
I own a 21, 27, and a 30. I can carry both the 27
and the 30 in an ankle holster, although the 27 does
fit a little better on my 175 pound frame.
I like the 30 better than the 27 due to the larger
grip, less felt recoil and the fact its a .45. It's
more accurate than I am. I don't feel that you
can go wrong with it.
Let the forum know what you decide to get.........
