Nice set of grips for Colt revolver.  I removed these from a Python.  I was told they will fit a Trooper, Police and Python.  The E & I Frame.  grips include the brass screw to attach them to your gun.  If you want a larger. target style grip on your gun, these are it.  They were too big for my hand.  Will consider 44 mag or 45 long colt ammo in trade.
