For me it has to be the "N" frame guns. First would have to be the early 25-2 with the 6 1/2 inch barrel. I suppose because I can use the 45 ACP round in the revolvers as well as my Colt autos. Next up would have to be the model 29 with the 6 1/2 inch barrel, because the 44 special load is just so accurate and pleasent to shoot. And in my opinion the model 27-2 is one of the best crafted revolvers S&W ever made, and you just can't beat that 38 special load. I did own a registered mag. a while back and it had the absolute best action I have ever held in my hands. Well thats what I like and I'm sticking to it. Its really fun to see all these different post and likes.
