.....WHY?.....
This is just my own opinion of course, but the new 327/627 can't hold a candle to the older true classic M13! The M13 quality, fit and finish, no I/L, lighter, smaller, and IMHO better looking is hands down the better gun.
About the only thing the 327/627 has over the older 6 shooter is the capacity. In today's world, I would not be carrying a revolver any longer as I do prefer the higher capacity, smaller size, lighter weight, easier reloads, better sights and easier to shoot accurately and rapidly Micro 9's for SD.
While I still own a plethora of S&W revolvers, they are all older models. I believe the newest S&W I own is a M60-7 which I believe is from 1994-5 - or maybe my M65 - don't quite remember when I bought it.
My suggestion would be is if you are still hellbent on the new 327 or 627 just buy one, test it thoroughly BEFORE selling the M13. Then you can decide wether or not to sell the M13, the 327/627 or keep both.
I want the S&W Comp Carry... but I feel like I am missing out on the latest and greatest technology. Because the prices of these 3 inchers have gone up so much I’ve been thinking of trading it for a 3 inch model 627 or 327, something about the S&W 8 shot revolvers really intrigues me ...
