ducmarc,

What is a P17? I am familiar with the British P14 or Pattern 14 and the US Model of 1917 but not a P17 but not a P14.

The Argentine System Colts are made on equipment sold to Argentina by Colt so all parts should be fully interchangeable. I have one of these also. Mine is from the Argentine air force and was refurbished by the Argies so it is a gray phosphate parkerized finish.
