It may be blasphemy on the this forum, but I like this model more than I do the S&W M-10!
I don't believe that they made many of that last series - seems like everyone wanted adj. sights - even if they never fiddled with 'em. They're not uncommon, but can be hard-to-find with your barrel configuration - looks like you got one with a wide hammer spur, too!
There were actually two barrel types of the fourth generation. Yours with the partial lug, and one with the full lug. I like the looks of yours better than the latter. Yep its time for a range report!!
I did try it out with a couple of boxes of just generic ammunition. Great revolver...it does shoot as good as I had expected. I do have a Diamondback, so I knew it probably would. It locks up tight when you have dropped the hammer on a empty(emphasis added) cylinder and keep the trigger pulled back and try turning the cylinder. I mainly shoot at 50 feet and was able to keep all shots within the size of a quarter, OK, I exaggerate, MOST shots were within that size. LOL. I credit the excellent craftsmanship of Colt from the 1970s. According to the serial number it was made in 1978. It is almost as old as I am. :shock: :lol:
It is a very nice Police Positive. I do agree with Leighton. I do prefer the half barrel shroud as well. On a nice small/medium frame revolver like this in .38 Special no full lug is needed.
