Medium, even though I don't own any...yet. I tried one, and liked it (I thought I might).
SOLID. I hate holey triggers. Slanted slide serrations and a few other things that give traditionalists fits of the vapors don't bother me, but holey triggers do. Good for lint catching, and that's about it.
If a guns sticks around, the holey trigger ends up in the same parts box with FLGRs, plastic mainspring housings, and hex head screws (at least hex head screws work, unlike FLGRs- I just never have a wrench handy for them).
I put medium, because I'm a Glock fan. Not sure how the Glock trigger-pull length translates in 1911 terms, but I've definitely pulled longer and harder triggers. The holey and slotted looks are attractive, but I can't imagine they affect trigger feel or pull.
