Drill-out (lighten) hammer?

Who has done this and where/how deep was the drilling? Considering lightening the hammer on a GP-100 and Redhawk. I was thinking about drilling-out the forward face of the hammer, just below the firing pin recess (dimple).

ok, sorry for my ignorance, but whats the advantage gained by this?

Im hazarding a guess at it being lighter so you can run lighter hammer spring to get the inertia to strike the primer?

firescout, Good luck with that ... Ruger hammers are harder than woodpecker lips. Yes, I have drilled out a few GP-100 hammers and was able to reduce the weight by 25%. This decreases lock time but don't expect a lighter hammer spring to get positive primer hits.

I, too, question the need for this and would expect problems with ignition. It's easy to remove metal....much harder to put it back. If you're going to try it, do it on an "extra" hammer so you can undo, if necessary.

Just remember, the dremel tool is the gunsmith's way to early retirement.. Have you considered Wolff springs?

Thanks for all the replies so far. If you have to ask 'why', then you don't understand the concept. Iowegan got it right: decreased lock time. Both revolvers already have reduced power springs installed, with 100% primer ignition reliability.

I mainly wanted opinions/experiences with this concept and if it was worth the trouble for the benefit. I would be using a carbide tool and milling vise setup to accomplish the job.

I would definitely order a couple of spares from Numrich...just as a backup.

From experience I wouldn't lighten the hammer too much. Yes, you gain hammer speed, but with the lighter hammer spring you would also run the risk of light strikes. Even though the hammer would be moving faster, it wouldn't have the proper mass to dent some primers. It's no problem in a range only pistol where you can afford light strikes occassionally, but never for a SD pistol. I've experimented with custom skeletonized hammers in the past with good & bad results. Worst case is you might have to replace the hammer & try again.

Except....one cannot get hammers from anyone, usually. Ruger considers it a factory-fitted part. Therefore, the idea becomes even less appealing.

I have had a Blackhawk hammer on back order from Midway for just about a year now.

Numrich seems to have both GP100 and Blackhawk hammers in stock right now.

Since woodpecker lips are right up there in hardness with carbide, I'll probably forego the drilling of the hammer.
