Due to my father-in-law’s recent passing, I am a new, uneducated gun owner. I have a Smith & Wesson 22 Long Rifle CTG revolver. I would appreciate any info I can get, especially its age. I tried to research it, but most of them I have seen online have a letter, usually K, preceding the serial number. Mine does not. The serial number is 276xxx. It is stamped in at least 3 places. Also, most 22 LR CTG’s seem to have a number on the butt of the handle. There is nothing on mine, as seen here. There is also a number on the frame that can be seen when the cylinder is swung out. It is:
A
51149
…o

I was also wondering if this would be good for recreational target shooting.
Any info is greatly appreciated.
