Wilson Combat says they only supply 3 hole triggers on their pistols and no other style because of what they call "trigger bounce" to which I don't know what they mean. I like solid triggers, but should I re-think this because of Wilson's claim? Thanks>

What they're probably referring to is the tendency of heavy triggers to bump the sear due to their inertia when the slide is released from slidelock, etc.

With modern aluminum triggers, trigger bounce is mostly a non-issue on all except the ultra-light trigger jobs.  

Dane Burns used to sell a solid trigger with no overtravel screw hole and hollowed-out cuts on the rear of the trigger shoe.   It weighed about as much as a 3-hole trigger but had no externally visible holes.  

Look here for the "Hard Use" trigger.

I'm no 1911 expert but my understanding is that the lighter the trigger, the less likely it will be affected by inertia under recoil, and "bounce" off the hammer hooks on the sear, which could cause the hammer to follow.

Ahh...  here's a quickie google explanation:


One of the areas where you want to be especially careful about modifying your 1911 is in the area of trigger pull. Ever seen the hammer follow on a 1911? You're firing the gun, the slide cycles and recocks the hammer, but instead of staying cocked so you can fire the next shot, the hammer follows the slide down and falls to half cock. The same thing can happen when dropping the slide while loading the gun. I've seen both these things happen and have had them happen to me.

You almost never see this happen on a stock gun. You'll see it most commonly with guns on which some enterprising pistolsmith has lessened the hammer/sear engagement and fitted a heavy steel trigger and added a heavy recoil spring. When the slide slams forward on the gun, the gun moves forward, but the heavy steel trigger wants to stay in one place (it's called inertia, folks), so it actually moves back slightly in its track. If the hammer/sear engagement has been compromised, either through taking off too much metal or changing the angle of the hammer hooks, the trigger can actually bounce far enough back to jostle the hammer hooks and sear out of engagement, causing the hammer to fall to half cock.

Thanx gentlemen. This is really over my my head, but I'm guessing with a semi-custom I could go with pretty much whatever triggger I want at say a 4lb pull and be not be affected by this "inertia" syndrome?

yes, I think so. Also, solid triggers can be lightened to it would be a non issue anyways.
