What Pete said, lots on scope ring info and hammer mods info in the FAQs. Choosing a scope that's Handi friendly is the best choice, fixed power or variable scopes with a small power ring and/or ocular bell make a big difference as does being able to mount the scope (fore or aft a little) so it doesn't interfere with the hammer, the scope base makes a big difference in that respect, the Weaver #82 with the unusable flat spot at the rear really a poor choice unless you take advantage of it and mount a small scope so it's entirely forward of the hammer, all of this is covered in the FAQs.
