Questions & Answers
Will this assembly drop into a Para Ordnance P-13 ?

Hi there, they are considered as "near drop in" fit on most production 1911s, as they may require minor fitting at the bottom barrel lugs to ensure proper lock up and battery function due to possible variations from each of the manufacturers of the gun you have.

Hi there, is this barrel truly a drop in part? Or does it require fitting from a gunsmith? I have a full size Springfield Armory 1911 A1. Thank you.
