If it ain't broke don't break it further by trying to "fix" it
It probably locks up great with that extra litttle bit of bolt popping up
I have a Pietta that has a bolt that is dropping right before the leade, it's made a little ding in the cylinder but it works just fine, I thought about trying to clean up the bolt but it works perfectly fine so I just shoot it. With my luck I'd ruin the bolt and make the lockup sloppy on an otherwise tight and functional gun by trying to fix a non existent problem. If I cock the gun slowly you can kind of hear the "crunch" as the bolt just hits the tip of the leade but if I cock it like a man like it's supposed to be used or like CAS shooters cock them, it works just fine.
Like how people complain about old S&W revolvers not "carrying up" right if they cock them in super slow motion like some dude on YouTube showed them to "test" for timing......, but a normal trigger pull or hammer cocking effort and they carry up perfectly. A lot of them left the factory like that to build in some "slop" so they can function dirty. People spend $$ and time having this "fixed" when the gun will probably work perfectly for 100 more years when used as designed.
I learned this from my gun shop owner years ago , I had an old Smith and I'm like , the cylinder stops just short of lockup when I put my finger on the cylinder , point it up into the air and cock it very slowly.....he's like I don't know what kind of BS that is , just put rounds in it and pull the trigger like a man . it left the factory like that before I was born and it will work long after you're dead, just shoot it
