I've recently installed a Dave's Metal Works loader on my 1100 tac4 and have noticed alot of others have shortened theirs. I have noticed it does bite a little when loading, I assume that's why some are cutting the forks back????????????????
Haven't got a chance to shoot a match with the loader yet so I'm open for comments.
No, your assumption is incorrect. The main reason folks shorten them is to reduce the moment of inertia. This reduces two significant problems common with the full-length EZ Loader: (1) bolt closing on an empty gun, and (2) roll pin breaking. You should definitely shorten and re-profile your EZ Loader; anything in the range 1/2 to 3/4 of the original length will work, but make sure a round that slips past your thumb will not prevent the round from being removed.
While you are working on the gun, make sure the magazine spring is nice and strong - weak mag springs can cause other problems unrelated to the EZ Loader.
Lastly, be sure to test fire the gun thoroughly before your first match... a match is a really lousy place to discover that your EZ Loader needs some adjustment

.
OK, I've put about 150 mixed rounds through it and had to adjust it once already because of the bolt closing on an empty chamber during drills.
Say about 1/2-3/4 of it's original length, I should be able to do that without removing it, again. I'll remove some of it and see what happens.
Anybody else's experence would be appriciated.
I cut mine without removing it from the carrier. GO SLOW ! I stuffed some scrap wood between the EZ loader and the carrier to protect the carrier from inadvertent damage. I shortened the EZ Loader using a Dremel cutoff wheel, then I smoothed/shaped the tines of the EZ Loader to mimic the original profile. Here is a picture showing how much I shortened mine:
