Recent impulse buy, I've never had a mag fed shotgun before.

Bought additional m1919 style mags and after first or second shot the next sees to get hung up on the feed lips. Or could be something else causing the shell to become stuck in the chamber (at an odd 45 degree angle still attached to mag).

I'm still in the break in period so I'll give it a good once over again.

But I'm wondering if anyone has had to modify their mags?

Wanted to ask before I broke out the dremmel.

Thanks
