10 years ago I got (5) Colt police Positives for $80 each from AIM.
They have the name of the police agency on the back strap of the frame welded over.
They had lots of holster wear, but like new inside.
On a couple of them I have cut ~1" off the butt and put on a gripper grip made for a Colt Agent.

The max load for Hodgdon 357 mag LIL'GUN 158 gr is 18 gr.
And the Police Positive is a 38 special, not a 357 mag.
But I have been shooting 26 gr LIL'GUN in my Colt Police Positives and it kicks harder than a 44mag!
