bobbing a hammer spur...need some ideas

hoytinak · June 14, 2009, 09:46 PM

I'm picking up a cheap snubby .357 tonight and wanna bob the hammer. I know many on here have done it themselves and I'd like to see some pics to give me an idea of how much to take off. It will be fired in DA mode only so I won't need to leave enough to cock the hammer back for SA fire. But I've heard I might need to leave a little for the weight to keep proper timing. So let's see your bob jobs.

Take care or you might end up with a gun that does not work. Snubbies are usually small, light guns and the hammers are also light. To fire primers reliably takes a certain momentum (mass times velocity), and lightening the hammer by removing the spur can reduce the weight enough to result in mis-fires. This is even more true if the spring tension is also reduced as in most "trigger jobs."

So I would not "de horn" that hammer unless I had a new hammer on hand and I would not carry a "de horned" gun without a lot testing to make sure it is reliable.

Jim makes a good point - have a spare hammer.

That being said, I've de-spurred the hammers on two snubbies with no problems. The first one was a 2" S&W .357 Magnum. I don't remember the model number. It worked great. The second was a Taurus 85UL. I also installed a lightweight set of Wolff springs on this weapon. It functions flawlessly. On both hammers, I used a Dremel with a cut off wheel to grind off the spur even with the body of the hammer. Then I used a sanding drum and emery wheel to smooth and polish the surface. You can't tell it from a factory job.

I bobbed my own Snubs with no problems. I did it on my bench grinder with gun still together.

A Dremel tool would be pretty handy.

What make and model?

I've done a J frame Smith, but had someone else do my Colts.

hoytinak · June 20, 2009, 11:18 PM

It was a Rossi 462.

Well, I guess this thread is pretty much a useless thread now as I have already traded it off. It was just too heavy for what I was wanting. I'll end up getting a LCR soon, so I won't need to worry about bobbing it.

KCabbage · June 23, 2009, 03:15 PM

I'm not trying to be a smart allec, but what's so special about the LCR?

The answer is simple for me.....it's a Ruger.

rantingredneck · June 23, 2009, 07:20 PM

Indeed ^.

But combined with that, plus the trigger, plus the light weight, plus the recoil management...........well.........what else can you ask for?

doc540 · June 23, 2009, 07:22 PM

With a Dremel I did this semi-bob on my wife's M36.

Work slowly and scribe or mark how much you want to remove. Then polish the edges.

Fellow Texan did these full bobs on my Colt D frames:

All 6 models at the last Shot Show suffered broken firing pins from folks just dry firing to test the trigger pull. Ruger has, once again, recalled a gun and, on the LCD, upgraded the pin. They may be fine now. Hope you'll get back to us and let us know how the R&D is coming.

I handled one recently, and was impressed with the nice T pull.

Actually, the gun is developing fans, while others are still a little "gun" shy.

Getting back to bobbing the hammer. I did two of them. A Det. Special and a M66. I cut off the spur with a dremmel cutting wheel. Then used a course grinder. Then not so course. I finished with craytex. Each step erases the tool marks left by the previous one.

I'd recommend (for those not experienced) you first cut the spur less than you want and do a "trial run".

Coarse craytex, medium or fine, then #6 Fordam tool compound. Finish with green compound if you want a high shine (like I do on feed ramps). Dremel accessories and polishing compounds can be found at a shop that carries jewelry, rock, etc., polishing equipment. Such a shop can be a very interesting place, and the owner in the one I visited was extremely patient with my million questions.

Not to beat a dead horse in a dead thread (

) - but before ANYBODY actually bobs the hammer on their DA revolver, they might want to try something first.

Try to de-cock the fully-loaded revolver without touching/using the hammer spur - without experiencing an AD.

If you'll tell us how you came to know better, I won't.

I don't care for Bobbed Hammer guns. :barf:
