Austrian Tupperware is my belt gun, mostly per work regs, but my primary pocket carry gun is a 442-2. Draws easily from the pocket due to the rounded contour and can count on five shots, regardless of shooting stance or quality of hand placement on the grip.
A 4” M10/64 can be carried concealed with a decent holster and a stiff belt that supports the weight and does not allow the gun/holster to slide around and smack you in the ribs with every step you take.
These revolvers can be had in cosmetically rough but excellent mechanical condition for $300 and up. Town Police here in Richmond has VA DOC 4” M64 trade ins for $300. There were three in the case yesterday.
There was a sock drawer condition 4” standard barrel M10 at another one of our local cop shops, Southern Police, yesterday for $350.
