Sorry to hear about your surgery, but glad to hear you're doing better.
If the old Colt .38 Special was a snub nose, then you'll probably do okay with this one. Being that it's a few ounces lighter than the regular weight snub nose revolvers, it'll have a little more kick but not that much more than you should be able to handle.
Yes, the Colt is a snub nose.
I'm thinking of buying a 22 revolver just to have one that is not a kicker. I know that placement of a 22 bullet is critical to stopping someone, and I'd use the 38s for that, but I might need to shoot a critter, not a human and I've nothing but these 38s.
Well, that is not true, I have a Remington shotgun and a Remington rifle, both new in 1998 and but both are too heavy for me.
