I just picked up a Sistema Colt 1927 and it's a JLD import. Looks like it's one of their Grade 3 (shooter) as it was heavily polished-so much so that the lanyard loop is 1/2 ground through! I threw in a Norinco MSH I had until I can replace the lanyard loop. On further inspection I found the barrel to be "ringed/bulged". The gun cycles fine and the prior owner states OK accuracy with it. I had a mil-spec bushing and a barrel marked ".45 AUTO." that I dropped in with a Kings #3 link. I seems to work. Is their any problem with trying this combo out? I'd like to see how it shoots with the orig barrel and bushing and then my replacement. And how tough is it to replace the lanyard loop? I can pick one up cheap-it's a USGI part. I'd like to know if it's the same and how tough is it to drive the pin out holding the loop in the MSH?
