I purchased a Investarms Kentuckian percussion pistol from an online auction based only on the pictures I could see in the ad. It was complete in the box with flask, nipple wrench, brush and mold for ball and bullet. It is .44 cal. Being in NJ I had to wait a month for my pistol purchase permit to come through before I could even touch it. I picked it up the other day and I can see it has never been fired. All the stuff in the box is new. But in the process of going over it I noticed the hammer is pretty far out of alignment towards the outside. I have shimmed the hammer on one of my rifles and that solved that problem but this has to go in. not out. so I took the hammer assy. off and right away I could see the poor workmanship behind these guns! I see there is a block that is part of the hammer housing casting and that is the problem, it is bearing on the barrel. I assume it is supposed to bear on the barrel for stability but it needs to be in further. I can take care of this by lightly grinding a little off of that block but before I do I wanted to ask if this is an appropriate thing to do. You can see in the pics what I have installed with it installed, partially apart to show the interference part and the two pics of it apart and you can see that little dot on the casting and the mark it made on the barrel. That is the area I need to grind down.
