GP-100 Custom Hammer

 This customer wanted a Python-esque hammer for both his blue and stainless Ruger GP-100 revolvers.  Given that the GP's proportions are similar to a Python's (chamber spacing and cylinder CL to bore CL), this allowed a much more faithful rendition of the Python's distinctively styled hammer.  The original hammer is an investment casting, while its replacement is machined from an O1 billet and fully heat treated before finishing.

Since I don't use CNC anything, each of these cuts requires a different setup.  The final machining operation is to narrow the portion of the hammer that isn't the spur.  Everything after this is hand work.

The hammer after final shaping and checkering but prior to heat treating and finishing.

The finished job:

  1. Amazing work as usual.

  2. Lovely work on the “G-Python 100” hammer!
