I have one GP-100, I'm currently shopping for a Security Six.
Why? Own the GP-100 because I think the .327 Federal round is fun and I do enjoy goofing with some off-beat stuff and for .327, I wanted a double action. If Smith & Wesson made a K-frame .327 Federal with a 5 or 6-inch barrel, I'd have bought that instead. The GP-100 and it's 4.2-inch barrel is where I landed. It's a fun revolver but I have more than a half dozen S&W revolvers that I like better than my one GP.
I'm chasing a Security Six because of nostalgia. The first centerfire handgun that I ever shot was a 4-inch Security Six stoked with 158gr .357 Magnum. I was 15 years old and quite apprehensive at exactly WHAT it was going to be like.
Apprehension transformed in to
passion somewhere between #1 and #6 chamber.
So I believe I ought to own one of these revolvers, many years later, but I refuse to pay -any- more than I think I ought to pay for one. To that end, I missed a stainless 4-inch Security Six at a gun show one week ago over a TEN dollar difference in price between myself and the seller. He tagged it at $450, I would have been happy to pay $375, but I elected to go over my comfort level and offer $400. He said he had $400 in it, so he wouldn't go a penny under $410. He said it was just on principle -- and I felt exactly the same way. The entire discussion was as friendly & good-natured as could be, and we parted ways with smiles.
I'm glad I didn't bring that one home. It felt very nice but it was far from mint. I'm not at all scared of a used gun that's far from mint, but I've got to be happy with the deal.
