In my case the sight that came on the gun wasn't that tight. I thought fixing the barrel made more sense. I figured every sight would probably be loose.
I'll have to shoot the gun more, but my plan is to use the primitive sight for rendezvous, and install a peep on the tang for hunting. If I use the Lyman peep it bolts on and off easily. So, I have no reason to change the primitive sight.
I want to shoot the primitive sight though. I might just use it for everything. My lock was messed up, so i'm waiting for a new one Lyman is sending me. Then I can go shoot.
Once i'm sure i'm keeping the gun. I'll send it to Jon to brown and defarb the barrel, and a little stock work. Then I can go to work on my Stith Hawken kit. It's going to take me forever to build, and I want to get started right away. Plus Jon can probably use the extra cash.
