You've said alot in your post. The model 13 developed from the Model 10-6,which was a heavy barreled .38 Special. They are hard to find,as I believe most people find them a good shooting,dependable,and diverse revolver with everything you need and nothing you don't. You can shoot anything in it from mild mannered .38 target loads to full house magnum loads,all in a handy K frame package.
Contary to "Pistols"s post the Model 13 was a .357. My PD in NJ issued them in 1975 and we used them for daily carry until 1986 when we went to semi's. Department cost back then was $70.00. Bought mine from the Dept when we switched and just sold it for $350.00. Was a great revolver.
Thanks for the imformation guys! I know stainless wears better but I love a deep blue revolver, sometimes shiny is not better! The 3 inch barrels are nice but a 4 inch can really reach out.
IMO, the 3" M13 is the CCW/Fighting wheelgun to have. Here's a pic of my Sokol Custom (ChestnutMountainSports.com) M13. As you can see from the pic, it's carried a lot. I had Karl do the following:
-bob hammer
-action job (smooth without reducing trigger pull weight)
-round serrations off trigger and install overtravel stop
-chamfer chambers
-dehorn all sharp edges
-remove damaged front sight and install dovetailed replacement
-hard nylon grips
-parkerized finish
He also did similar mods to the 2-1/2" P&R M66 in the pic, too.
It sounds like you think the 4" is more accurate than a 3". Maybe a little, but I've never had a problem hitting a 12"x14" steel plate at 100 yards offhand, double action. I used to do it all the time with the 3" M65 that Karl built for me (exactly like the M13 he did for me, but SS) when I turned 21. When you get comfortable with it, hitting at long distances is not a problem, 3" or 4" barrel.
Pistola is correct, the very early fixed sight K frame .357s were built on model 10-6 frames and stamped as such but with .357 marked barrels, prior to the model 13. They are found for sale occasionally, I think there is one on GB right now.
