Frequently Asked Questions

What is the purpose of removing the hammer spur on a revolver?

Removing the hammer spur, often called 'bobbing' the hammer, is a common gunsmithing modification. Its primary purpose is to prevent the hammer from snagging on clothing, holsters, or other gear during a quick draw, which is particularly useful for concealed carry or competition.

What tools are needed to remove a hammer spur on a Smith & Wesson revolver?

To remove a hammer spur, you'll typically need basic disassembly tools, a vise to secure the hammer, and a rotary tool (hand grinder) fitted with a cut-off wheel for the initial removal. Grinding stones, sanding drums, and polishing heads are then used for smoothing and finishing the modified area.

Can I remove the hammer spur myself, or should I seek a professional gunsmith?

Removing a hammer spur is considered an intermediate-level DIY gunsmithing task. If you are comfortable with basic firearm disassembly and using power tools carefully, you can perform this modification yourself. However, if you lack experience or are hesitant, it's always best to consult a qualified gunsmith to ensure proper execution and avoid damaging the firearm.
