Just screwed in a new 1/4 x 28 spitfire nipple into my t/c renegade, perfect fit. But the hammer, by just the tiniest little bit, when I let it down carefully on the nipple doesn't come down flush on the nipple. The edge of the opening on the hammer barely hangs up on the tip of the nipple and prevents the hammer coming down the rest of the way. I'm sure this has come up before, and I'm counting on you guys (and gals, of course) to give me a simple solution. Thanks!
