Yup.

The 27 is just the finer finshed version of the 28, both big but tough. I bought my 6" 28 while I was in the Air Farce, carried it 'til the CHP allowed 4", had it rebarreled. After rebluing it several times (Hoyte breakfront holsters are rough on bluing) I had it Armaloyed (GREAT finish). Still have it, altho it, and all but one of my other handguns, is at home in the gunsafe while we are on the road, seeing the world...
