I like them. These are actually Colt Police Positive Specials. Except for the one on the right, which is a 22 Rimfire Police Positive Target. The one in the center is chambered for 32-20, the other three are 38 Specials.
In 1905 Colt patented the Positive Lock, which featured an internal hammer block that prevented the hammer from falling all the way unless the hammer had first been drawn back to full cock, or the trigger had pulled the hammer back in double action. That's where the name comes from.
The first Positive revolvers were 32 caliber. This photo compares the size of a Smith and Wesson 32 Regulation Police at the top to a Police Positive 32 in the middle and a Pocket Positive at the bottom.
A 'regular' Police Positive is chambered for the 38 Colt New Police cartridge, which is interchangeable with the 38 S&W cartridge.
Not the same as 38 Special! 38 S&W on the left, 38 Special on the right. Besides being longer, the 38 Special bore diameter is slightly smaller than the 38 S&W. .357 vs about .360 if I recall correctly. A Police Positive 38 cylinder is too short to accept a 38 Special. Although some have been reamed out to accept the longer round, so one does need to be careful.
Sorry, I don't have a photo of a 'regular' Police Positive to show you.
Almost the same revolver, with a slightly longer cylinder and frame is the Police Positive Special, like the ones in the top photo. Long enough for the 38 Special cartridge, or a few other cartridges such as 32-20.
The frame of the Police Positive comes about midway between the size of a K frame Smith and Wesson and a J frame Smith and Wesson.
I can't believe I don't have a photo comparing a Police Positive to a K frame Smith and a J frame Smith. Must correct that.
Perhaps as a consolation prize here is a photo of a Police Positive Special at the top, a Colt Detective Special in the middle and a J frame S&W Model 36 Chiefs Special at the bottom. The Colt Detective and Police Positive Special are built on the same frame. Notice they are both six shot 38 Special revolvers. The slightly smaller cylinder and frame of the S&W limits its cylinder to five 38 Special chambers.
Yes, Police Positives have not been made for a long time. They were made from 1905 until 1947. There are probably very few gunsmiths around any more who know how to work on them, unlike S&W revolvers which are a bit simpler to work on.
Some don't like the smaller frame of the Police Positive, compared to a K frame S&W. If it feels comfortable in your hand, then go with it. Just remember to buy 38S&W ammo, not 38 Special.
P.S. This photo will have to do for now. Colt 32-20 Police Positive Special at the top, K frame S&W 32-20 Hand Ejector at the bottom.
