I am picking up a spurless hammer (Bobbed Hammer) for my old S&W model 36 and was wondering how hard it is to change out the hammers.I have worked on 1911's but have never done any thing on S&W revolvers.The hammer comes complete and I believe it is used.Thanks for any help.
How hard is it to change J frame hammers

Put the sear from your hammer on the bobbed hammer and try it. Frequently that's all it takes.
Is that easy to do?

Do a search on the revolver or gunsmithing forums. There is a whole bunch of good advice. The hammer comes out real easy. You'll need to remove the side plate screws, whack the gun till the plate flips off. Then partially cock the hammer so you can insert a paper clip in the hammer spring hole to remove the spring. Partially cock the hammer again and wiggle it out.
Do a search and you'll fine better, more detailed descriptions.

On a J frame, it is a good chance you wont even have to change the sear.

Only if the hammer is used and the sear was fitted (in a different gun but fitted). The pinned sears were usually trimmed/shaped appreciably to "trade off" properly.

Two Guns I'd appreciate if you would post and let me know how the switch works for you. I recently acquired a M37 with a bobbed hammer and was thinking about going the other way with it. I've got the Kuhnhausen Shop Manual but I'm a loooong way from being a gun smith. I'm confident I can replace a hammer easily. Not sure I've got the skills to "fit" a hammer though.
Will do......I should have my hammer by Friday.
I ordered 2 full hammers for my 37-2 with bobbed hammers.
After getting the correct sear, they dropped right in.
I had to e-mail S&W with pictures, and they hooked me up!

Thanks for the info!
Andy the change was easy.The hardest thing for me was to get the side plate back on.The whole trigger change took about 10 minutes.

Thanks Two Guns. I'm sort of liking the bobbed hammer on the 37. May leave it as is. But at least I know it's not too hard to change if I decide to.

Did you swap sears or use the sear on the new hammer? Did you get a new or used hammer? Thx.
It was a used hammer and I keeped the sear that was in the gun.The trigger pull is better now than it was before. The Model 36 is the top gun.

Thanks, follow-up like that puts things in perspective and helps those who want to do mods like this.
I just changed out the hammer on a 696, after Smith sent a new hammer to replace the defective hammer they sent originally. Dropped it right in.

Parts "fitting" on MIM guns vs the older forged parts guns is a whole different game.
