Bob The Hammer?

[Sulaco]

I have a S&W 637 and someone on another forum brought up bobbing the hammer. I am interested if this is something I can do at home with a Dremel tool or some similar means. Can anyone give me some info?

Thanks.

Also, how would this affect the primer ignition given the hammer's mass is what creates the inertia needed to push the firing pin into the primer? I don't want to monkey with springs and whatnot.

It's much better if you can disassemble the gun and get the hammer out.

It's easier and less risky to the gun if you can put the hammer in a vise and work on it.

Most revolver hammers are case hardened and it's difficult to cut the hammer with a hacksaw.....difficult but NOT impossible.

Other options are to use cut-off wheels.

Whatever, after the spur is off you can clean up the cut with stones, files, or abrasive cloth wrapped around a file.

In MOST cases, removing the spur will have no effect on reliable ignition.
In some cases, it may even enhance ignition, since the hammer will have a faster fall, and a "sharper" strike.

I had a friend who put his S&W hammer to a grinding wheel. It looked really nice after the final cleanup. I always wondered if one could purchase such a hammer from the factory. Seems better than grinding away.

You will still be able to cock the hammer back even after you bob the hammer, unless you do some more work to the internal portion of the hammer. This may not seem like a big deal until you want to safely decock the hammer, and don't have a hammer spur to assist you. If you're going to bob the hammer, it's probably a good idea to go all the way and make it DAO.

You could still decock the hammer by swinging the cylinder out, then dry-firing.

Whoops, oh yeah.

 

[dfariswheel]

No, you can't.
On modern revolvers when the hammer is cocked, the cylinder can't be opened.

You can often find factory hammers that are converted to DA-only with the spur cut off.

Well there is a safe way to decock a spurless S&W hammer but that would just start a big bruhaha.

I don't understand how you get a spurless hammer cocked in the first place.

 

[dfariswheel]

Two ways.

On the Colt Detective Special, spurless hammers can be deeply grooved or checkered on the top of the hammer.
This provides just enough gripping power that you can pull the hammer back.

The other method is a hair-raiser.
On this one, you start the hammer back......by pulling the trigger JUST enough to allow you to hook your thumb over the hammer and pull it back to full cock.

Needless to say, there's a high PROBABILITY of pulling just a bit too hard and firing the revolver before you intend to.
No matter HOW careful you are, sooner or later you "bobble" it and blow a round off.

NOT SAFE.

NOT SAFE.

Of course it not.

Most people can't even decock a 1911 safely and it was designed for that.
