Hi, cratz2,
In the result, you are correct, but "hammer bite" is not due to pinching the skin. What is not usually realized about the 1911 type is that when the gun fires, the slide moves backward very fast and strikes the hammer a hard enough blow that it loses contact with the slide (yes, I know that is not what the pictures show, but it is what happens). The hammer then continues back and down past the full cock point until it is stopped by the grip safety. In the process it can contact the skin if the shooter's hand is a little fat or a high hold is used. But there is no "pinching"; the hammer has struck the skin a hard, fast blow, like being hit with a fast-moving whip end.
WWII and later hammer spurs are not long enough to reach down past the grip safety and most folks are not bothered. But the short grip safety and long spur hammer used on the old Model 1911 were very nasty for a lot of shooters, though I have not been able to confirm the report that the inventor of Band-Aids was a pistol shooter. The recent Argentine imports - all Argentine-made pistols and some Colt-made pistols - have long spurs and do damage.
The beavertail grip safety cures the problem, of course, but at the expense of making the pistol longer.
