Recently bought a Pedersoli 1886 from Taylor’s with a pistol grip stock. Shoots well at 100yds with a 405 hard cast powder coat bullet. Wanting to stretch it out a little more so I bought a “long range” tang sight, Pedersoli’s Universal model 430. While the bolt pattern matched the hammer hangs up and blocks the bolt from sliding. The culprit is the sight base is too thick. While I could have it and the screw head machined down I think I’d rather sell it and try something else. Anyone know what brand and model sight would be a direct bolt on for this rifle?
