Is this competition-legal?

https://ibb.co/JkT5qR5

My hammer broke. A piece of it flew off while I was shooting. I tried to fill it in with JB Weld but that flew off also. Can I shoot a match with it like this, or is it going to be flagged as a safety violation? The pistol still shoots.

I would replace this hammer without any hesitation. Even if it is legal and presumably safe, the fact that it broke like this signals that something is wrong with the metal, either a manufacturing defect, or metal fatigue, or incorrect metal composition in the alloy, or a combination of the above. C&S makes excellent hammers, also KC Crawford,  EGW, Ed Brown, Wilson Combat, etc, plenty of options to choose from. Buy once, cry once.

Thank you sir. But I had a trigger job done on this pistol. Will I have to have another trigger job done on it if I replace the hammer?

Not necessarily, if the hammer is within the specs and from a good reputable manufacturer. But can't say for sure.

Talk to the smith who did the trigger work, they will be able to tell you their recommendation on replacement . I agree on not running it, why risk it breaking when you need it to work correctly

I agree, stop running it. Whatever is going on with this particular hammer, the spur is not so high stress for it to fail this way. Must be metallurgical issue, tempering or mim if it is mim, stress cracks at the manufacturing...maybe? In the best case nothing more will happen, you may even bob it completely to look undamaged. However, if it does fail at the actual striking part, then it will chew up the bottom of your slide.  Safer to replace it. Something decent will cost you 60-90 ish and will likely be already cut to proper angles. While not a custom trigger job it will be good enough as a drop in.

As to your original question - not sure if competition legal as is.

Quit shooting it! That is a first for me seeing this and I have been around the game for a while. That part looks defective. Looks like maybe a cast part. What is the origin of the part and manufacturer of the pistol?

It's a Range Officer. My gunsmith dremeled a slot out from the center of the hammer to lighten it. I have 15,000 rounds through the pistol.

I might sell this pistol and my Nelson kit if I could find a buyer locally. It's causing me so much aggravation recently.

That was foolish and unnecessary on a MIM part. Tool steel parts can be lightened but a MIM is waiting to break just because it exists! On the RO platform I have seen every MIM part fail! Replace it with a quality part from EGW or Harrison.

What is MIM?

“Metal Injection Moulding”.  Which is actually a misnomer.  In MIM, a powder and binding alloy is injected into a mold and the mold is heated  and placed under pressure.  The part then fuses.  It is a net-shape forming process.  It was kinda-sorta derived from sintered-metal production.  

Done correctly, the parts can be very good.  But, like all these things, process control is key to having these parts work.  Obviously, the process was not controlled well for this part.

MIM is a variant (sort of, but there are big differences) of die casting process that creates much stronger parts than die cast, but weaker than forged-machined.

^^^ what Wobbley said ))

Also you can trust what Jon Eulette recommends.

If for whatever the need/want may be for a lighter hammer, consider a Doug Koenig Hammer. You can get them from DougKoenig.com and Brownells.

Thanks guys. I am grateful for the help.
