In the K frame, there are 3-inch revolvers in Models 10, 13, 19, 64, 65, and 66.

Don't forget that there were 3-inch J frames in Models 36, 37, 60, 640, and 642, and perhaps more.

Most of the ones listed are not produced currently, and you would have to find them used.

The newest Model 66 is available with a full-length ejector rod in a 2.75 inch barrel, and that looks to be a good choice. Naturally, the adjustable sights allow you to "dial-in" your load of choice.

Good luck!
