Bobbed and skeltonized hammer

[Colt44]

Trying to lighten up the hammer. Did I go too far?

If it sets the primer off, then no you didn't. In any case, you did a nice job.

What kind of revolver is it off of?

 

[Colt44]

It came from a 629. Bought it used so I didn’t have to butcher the hammer on my 627 v comp.

 

[Colt44]

Haha. Copy that. Thanks Jim!

You can't get a hammer too light until you weaken it and it breaks. On a S&W centerfire revolver. The lighter the hammer the more reliable the setting off of rounds providing you don't change anything else and the gun is in spec with things like endshake, etc.
If you put a lighter mainspring in the gun and get misfires it is not because of the lightened hammer it is the mainspring if that is all you changed.

That’s exactly what I was concerned about, the strength of the hammer after I drilled the hole in the hammer. The original weighed 478gr and the bobbed one weighs 330gr. I just finished installing and test firing and am pretty pleased. %100 reliable with federal primers! 6# DA and 2.5# SA (not that SA matters anymore, just had to measure it for fun).

 

[Colt44]

Pretty happy with my final result... 6# DA trigger with %100 reliability using federal primers.

The hammer merely transmits the energy provided by the spring. I have shaved them down to "not much left" and they fired reliably 100%. And I have always considered Federal primers to be the best - regardless of how easily they pop. I have used them excusively for almost 40 years.

Colt 44 it looks great! Did you do the work yourself? I am thinking about something similar with my GP 100 hammer.

Yes I did. Bobbed and smoothed it out with a dremel tool cut off wheel and sanding wheel. Milled the hole out at work since my cheap drill bits wouldn’t even begin to cut on the hardened surface.
