In the old days if you wanted a bobbed hammer it required a cut off tool and quite a bit of polishing. If you bought a new hammer it was a long time fitting, stoning a bit at a time.
Everyone hates on MIM, but I bought this Apex hammer from Brownell's during their BF 12% off sale and it sat on my bench for a while. Today being bored I decided to try it in my 19 Carry Comp. It dripped right in, no fitting and I swear the action is better than with the original "Performance Center" fit hammer. Now to go bust a few commercial reloads out back to be sure it still hits hard enough to set anything off.
The old school forged hammers still look nice all bobbed and polished though ...
