(e) A different contour hammer was designed with the lower portions duplicating Browning's design but with the upper end reshaped into a more nearly vertical straight spur. The front thumb-gripping surface was inclined about 45 degrees and finely checkered. I've always been one of those people who gets bitten by hammer/tang pinch with a GI .45. Eliminating the grip tang with any standard hammer made this a lot worse. Going to a near-vertical spur eliminates the bite altogether and makes the hammer much easier to control and cock as well as lightening it a bit. To keep the spur from being ungainly tall and hard to reach, I also stepped the back of the slide. There were also cosmetic reasons for this, as without it my thought in looking at it was always ‘look what some damn fool did to a perfectly good .45’. Detonics didn't put this hammer into production, which I always regretted as it was quite practical.
(f) The aft end of the slide was stepped as close as seemed practical to the firing pin hole with an angled flat running uphill and forward an inch or so ending with a radiused step just short of the repositioned rear sight. In combination with the new hammer shape this made for a very compact and easily cocked (and de-cocked) design.
