model 27-R8
I also have a model 27 with 5 inch barrel, and it an awesome shooter. I had to have a R8 (27) and paided the price for it. I also have a model 28 with a trigger job on it. Actually I like the 28 a little better then the other two. (there is no one around here I trust to do a trigger job on my guns.) South Houston. but I did pick up a Ruger SP100 a while back., it's double action is better than the two model 27's about about the same as my model 28. it's got a 4 inch barrel and it might be a little heavy, but it's a real accurate shooter.('o' I shoot double action almost always),, the only gun with as smooth as my 28 is another model 28 that I have had for about the last 40 years or so. A friend put a .44 special barrel on a model 28, reamed out the cylinder to .44 special, reblued the whole gun, and did a trigger job on it. the single action pull broke at 3.1 lb.s(ok, it was about 40 years ago.)(it also shot off a ramsome rest, a 1 1/2" group at 50 yards ) but I shoot all of them and love them all. and ofcourse there are others to play with. but any of the "N" frame smiths are hard to beat. but the Rugers in 100 and 101 are coming up just behind them.
