A friend of mine has a Para 14-45 that he has never been able to fire a full magazine through without issues. The main issue is light primer strikes. About one in five rounds will fail to detonate. He has tried multiple different ammo types with the same issue.
He has replaced the springs on the magazines as well as tried aftermarket mags. He also had a gunsmith replace the hammer spring to no avail. At this point I'm thinking maybe a headspace issue where the rounds are seating slightly too deep. Would a new barrel make a difference. Any other ideas? Should he just get rid of it? (That's my suggestion after all the problems he's had.)
The kicker is that he has two Auto-Ordinance 1911's that cost less for the pair than the Para and they have both performed flawlessly.
