Are those SLR magazine plates you were running on your Glock? I run those on my Glock 19 as well as the SLR magwell. I've had feeding issues while using mine, but only when the magazine was very full. Same issue as yours....an early jam.
I'm using Dawson precision EZ off base plates but I'm pretty sure it's the same issue as you're having. We're limited to 10rd magazines here in Massachusetts, but that 10th Rd has a lot of pressure against it. When I tried running the same magazine in my PCC it wouldn't even seat without the bolt being locked back!
