I just fit a Kart EZ fit barrel to a new Caspian frame and slide. The lockup is nice and tight, even contact on the lower lugs, very smooth unlocking.
In one of Gene Shuey's DVDs, he demonstrates a test where he inserts a pencil fully into the barrel and puts upward pressure on the breech end of the barrel while slowly pulling the slide back. If it binds during unlocking, then it's supposedly a problem, but he doesn't elaborate. When I do this, my barrel binds a tiny bit. Not a hard bind, just a click.
My questions:
What is the purpose of this test?
What, if anything, should I do to correct this?
Is there a possibility of peening the upper lugs if I shot it as is?
Thanks.
