My model 41 from approx 1958-59 has been shooting totally left of centre all the time it seems. I noticed the rear site was seized but with good advice from 2 of our fellow members I was able to fix that but the problem persisted. To-day at the range I removed the Compensator from this gun only to discover that the crown was almost non-existent on it. Without it now the gun shoots perfectly true and dead centre. Its almost as if its a brand new gun. I will continue to leave it off of course but I actually like the look of it with the compensator on. Has anyone else ever encountered this before?
