I purchased 3 items for my Buckmark from Tactical Solutions. A 4" threaded barrel, a fiber-optic front-sight, and an integral rail.
Installed them all at the same time.
Now the pistol shoots about 10" high @ ~7yds.
I had been blaming the front-sight, but it's the same height as my original sight. I've got the rear-sight cranked down as far as it will go.
I stuck a red-dot on it and it shoots great, so I don't really think the barrel is pointing at a funky angle.
Any thoughts?
