i like the small frame S&W 22s, the I frame, and picked up one with 6" barrel with the adjustable / target sights
[ made in 1923 ].....and it has superb action / trigger and is amazingly accurate and fun to shoot....so then i wanted to see how the Colt equivalent of a similar setup with adjustable sights would be......however the Colt Police Positive 22s which are about the same size and weight as the S&W I frame, are often very expensive ....so i keep bidding......and finally did get a good buy [ under 200 $ ]
on one by getting one chambered for the 22 WRF....which just may be an even better choice for small game ,etc.

from the serial number this one was made in 1910; this little revolver has some wear to the finish, but mechanics and bore look perfect, trigger is light and crisp......and i have at least 700 rounds of 22 WRF so it is not impractical for me.

also wonder if I could try the Jim Taylor trick that he does with the 22 mag: cut off the base of a fired 22 wrf and use it as a conversion or shim by placing a 22 lr into it, then using it.
