Rover, I know, it seems like a great oportunity for someone who already has cnc equipment to make a lot of money, Ruger is almost asking for it by not offering any hammers for sale. Someone could ask even more than Ruger asks for this, since You would get a "sophisticated hammer" rather than the same old borring, heavy, ugly one.

If You have someone who will not rape you financialy for getting this kinda work done - go for it! just like I sead before, think about the part within the frame - if you narrow this, the hammer will look like a missfit from a different gun.

I got my extra GP100 hammer from Brownell's. My goal is to weld a flat on top to fashion a target thumbpeice like the S&W .500 target hammer

You have a point but I guess one could leave a slight ridge at the top of the radius for appearance and to keep the dirt out. Problem is finding someone who wants to do the hammers. If there were a big enough market for these one could make a prototype one to use as a casting model and do cast hammers a la Ruger. The local APG gunsmith here didn't want to do them.

"My goal is to weld a flat on top to fashion a target thumbpeice like the S&W .500 target hammer."

It can be done as Jim Stroh of Alpha Precision does this, however, he is not inexpensive but is known for his metal work. His option # is 551 and cost $186.

I think one maybe could do better locally, pricewise.

I have to check on a local first. I'll keep Jim in mind. I have heard of his work
Funny, 2200 people were interested to view this thread ,you would think Ruger would be paying attention.

Jim Stroh is noted for his metal work and was trained as a chemist if I recall. I had him weld up and create a custom semi-wide trigger for a Python I had and it was great. He also fabricated a custom gold bead sight for a Magnum Carry and did some other metal work on it. Some people are afraid of welding on Rugers as the part is cast and not forged. Obviously it can be done. Good luck and when you get the custom hammer be sure to post a picture.

I just noticed you are in PRK. You might check with Alan Tanaka in Gardena. He is an APG member:

AT Custom Gun Works
atcustom@atcustomgunwork.com
17924 South Hobart Blvd
Gardena, CA 90248
310-327-2721

I don't think he welds but has a welder who does some work for him.

Possibly Gun parts corp ( Numrich)
I also think its a common part to Super Redhawk but don't quote me.(I stand corrected)
I'll look for the invoice.

thomashoward, GP-100 and Redhawk hammers are designed quite differently. Because the Redhawk uses a "single-spring" system, the hammer has a "hook" that holds the spring whereas the GP-100 uses a hammer strut for the hammer spring.

GP-100 and Super Redhawk hammers share the same design but are not interchangeable. To the best of my knowledge, neither Ruger or Brownell's has ever sold a GP-100 hammer. It has always been a restricted part that is considered "factory fitted".

GP-100 and SRH hammers look exactly the same so the one in your photo could be either one ... but it is certainly not a Redhawk hammer. The hammer in my IBOK photo came out of a GP-100. If you have the new DA Gun Guide, there is a graphic on page 53 that shows the Redhawk hammer hook.

Got all of your works saved from the beginning (Fore sighted sometimes)
pg 53 got it... No hook on mine so that makes me comfortable with GP 100.
We should all be buying extra parts before they go away
Thanks for your expertise

Good point. In the past have picked up extra hammers, triggers, hands, etc. at Numrich and elsewhere when they turn up. Probably should have bought some parts for the Redhawk when Numrich had them in a while back even though I don't currently have one. I would especially do this if down the line one plans to do action work or have it done. In the past I had a Redhawk the gunsmith ruined the single action by removing ALL the creep and ended up with pushoff. Had a lot of money in the RH with custom work that would have been lost sending it to Ruger. Also, eventually if one shoots the gun enough it is bound to wear out some parts.

The IBOK format has been changed to reflect copyright restrictions. It is now called Iowegan's Gun Guide

IOWEGAN'S GUN GUIDES SOLD OUT!
Due to tremendous demand, Iowegan's Gun Guides are currently sold out. Please note that a formal announcement will be made regarding the timing for the next printing (likely not until sometime in the Spring)
