Loader not sitting on...

Well, I know its more of a general question and not cocker specific, but since its a Trilogy I might as well post here :P I was trying to get my 200 round generic loader onto the top of it, and wouldn't you know it, its a tiny bit too large diameter wise to fit in snugly, so I was wondering, if I shaved off a bit of the outer plastic on the loader, would this cause any problems with ball feeding or stabilty in the loader? The amount I'm looking at taking off is less then 1 mm around.

No, you should be fine. People sand the necks of hoppers all the time

Thats what I figured, but just wanted to make sure before I tried it, since I've never had to sand down a neck before

Just take your time and you should be fine.
