Check to see if the barrel flat above the extractor has the same number as the cylinder. That year production should have numbers on most of the parts. If it does not match it could have been a 38 S&W cut to use 38 Specials and rebarreled. Be careful if you choose to polish the cylinder not to...
First off take it to a competent gunsmith and have him check the crown. No need to rebarrel if both can be cut to proper spec. again. The crown can be checked with a lamp light over the barrel and a q-tip. With plenty of light place a q-tip into the crown with the breech open or removed...
How about a 696 platform in a new caliber .41 Special? The .41 Special idea has been around since the 1930's so in a time of small powerful CC handguns I think it's time to bring this to fruition. Lets say a 3" barrel 696 5 shot with a load of 185 grains running 950 fps.
Welcome to the forum the K-22 has to be the all time greatest 22 revolver ever made. I remember back in 1975 I purchased a JP Sauer Medallion that was a close match to the K-22 for hunting rabbits. Then traded it for the real thing a K-22 and have never been without one since. Collecting S&W...
I've had a very nice late 50's Terrier for many years now in 38 S&W. A real peach to shoot very low recoil sad part is the low velocity. There still a nice lite carry revolver especially in a Round Butt. You have a very nice Smith with that extra family history attached to it. Enjoy
A 4" 29 would be my first choice or a 4 5/8", 5 1/2" Blackhawk. I'm a fan of shorter barrels 5" being the best to balance but hardest to find. If you happen to run accross a nice model 24 or 624 I wouldn't pass it up. Also don't turn your back on a .41 Magnum Model 57 one of the nicest magnums...
My experience with Colt's is "You pay the money and take the chances". Colt's are excellent investments if left un-fired. Firing one not only decreases it's value but opens one to other problems. I had a 1992 44/40 that had an over-tightened barrel and shot 8 1/2" to the right with all loads...
