The S&W M60.
I have attached a scan of a target of which I am rather proud. I supplied a shipment of .38 Spec S&W Mod 10 revolvers to the local Police back in the 1980’s and two detectives came into my shop one day with one, complaining bitterly that it would not hit a figure target at 10 metres. They only had three rounds left and I fired them standing, double action, in the 10 metre range at work. All three shots seemed OK to me!
The target has the three .38 Special hits at ten metres as one tight vertically elongated hole.
Well done and Thank You -
Here's a wee video comparison of two .357" Magnum snubbies - one 6 shot, the other 5 shot:
