Most revolvers are too bulky for me for the limited round count. Small size and light weight are the key features for me, which leaves the Pony Pocketlite as the number one choice of a Colt for carry. I went further with mine and cut off the ridiculously long tang, beveled the muzzle, softened the sharp edges and lightened the slide.
It is the only Colt in my hierarchy of carry guns from the smallest to the largest, depending on the threat level and clothing restrictions. Holster carry is not an option for me as I must be able to remove my jacket. (Remember the Sally Field character in Absence of Malice wearing a jacket on a hot day on a boat ride?) The progression is North American Arms Mini-Revolver .22LR, Kel-Tec P32, Colt Pony Pocketlite, Kel-Tec P11, Smith & Wesson Model 6906, Steyr GB, USAS-12 with 20-round drum, Barrett M82A1, .... Opps! Got carried away.
The Mini-Revolver is always in a pocket, where it has been for about 30 years. The Kel-Tec P32 is usually with me, replacing the Pony Pocketlite in that category, while the others rarely are. (The large GB is usually in off-body carry, along with several extra magazines.)
Over the years, as more attractive guns have been introduced, the primary carry gun has changed. Decades ago, there was nothing to beat a Smith & Wesson Bodyguard in nickel for pocket carry. When the stainless Bodyguard came out, it replaced the nickel one. When the Kel-Tec P11 came out, holding 11 rounds of 9x19 and being smaller and lighter than the Bodyguard, that replaced the Bodyguard. The Pony Pocketlite was on the scene with the Bodyguard and was often a choice when smaller and lighter was dictated. It then alternated with the P11 on the same basis. The P32 is so small and light it is hard to carry anything bigger now that it has become available. A mouse gun is always better than no gun.
