Doug Koenig Low Mass Hammer
These hammers are machined from tool steel, vacuum heat treated for long life and hard enough to hold a trigger job for tens of thousands of rounds. The geometry was changed to allow lighter pulls and the strut location was changed slightly to lessen the pressure when cocked. This part should be installed by a competent gunsmith, but requires minimal fitting. Many gunsmiths use the hammer right out of the bag with our hard sear and get awesome results. This is the most widely used hammer in competition today.
Put this in yesterday before a local match. (I needed to clean my 1911 anyway.) Koenig hammer was in place in about 90 seconds. My previous hammer would sometimes go to half-cock when letting slide return on empty chamber. The Koenig hammer had no such problem. The STI 1911 ran perfectly and I took first.
