I have seen pictures of the windicator.
Personally I would look in the used case for an old S&W in either 38 or 357. I know GB will sound off about this but look at the taurus revolvers.
But Looking around I have not seen lots of revolvers in cases like I used to.
Better question is what do you want the revolver for?
Carry, hunting, general plinking?
If you want if for carry or home, Any 4" or less revolver will be fine. I have shot a few 38+p rounds out of model 10's. (M10, M14, M15, M67,{38's} M66, M65, M13,M19,& M28 {357's} [Yes I know ther is a mod 27 but i don't think he will find one to fit his budget]) A couple to see where they shoot is not going to hurt the gun and carry them in the gun. The fixed sighted guns are M10, M13, M65, out of the group.
if you want if for hunting then i would look at models with adjustable sights and 357 mag. (M66, M19, or M28)
If you want it for Plinking then get a 22. I would get an Auto as I have 22 revolvers and just when you hare having fun! your out of ammo.
Some of the old beat up S&Ws are mechanically good. they just have holster wear. Good project gun to play with reblueing and adding an oil finish to the stocks.
Well what ever you pick good luck with it.
