Bobbed hammer on a 686

Your 686 is a later version with the lock & a frame-mounted firing pin, no?

In order of decreasing ease and increasing cost, your options are:

1. Take a dremel to the spur of the existing hammer.

2. Buy a replacement MIM hammer from Midway or Brownells, and take a dremel to it, swap in the sear and spring from the original hammer. MIM parts are pretty much drop-in, so there ought not be any fitting of the sear needed. And the new model sears just pop right out of the hammer.

3. Buy a forged DAO aftermarket hammer from Apex Tactical. This is the MacDaddy of revolver hammers, but you'll need to buy an old-style sear, stirrup, sear spring, sear pin as well, and the sear will need fitting. And the old style sear, being pinned in, takes a bit more time to fit, so unless you know what you're doing, installing an Apex hammer will include a trip to the gunsmith.

Personally, for most people, option #2 is the best option. It'll cost a few bucks for the hammer, but you'll keep the original hammer. And if anything goes wrong, you can just get yet another hammer while keeping the original.
