Sig P938 Ejector Problems..

I think...

I forgot to mention that if I push the ejector toward the frame with the slide off, it works smoothly. Any help would be appreciated. I tore it down, cleaned it up, and that didn’t help. The ejector has some very rough edges, but I can’t see what they’d catch on. Thanks for any ideas!

I filed down the rough edges and lumps on the cast ejector, and it’s working fine again. The pistol has around 600 rounds through it, and today was the first time this happened. I reversed the sear pin as well, so who knows.

EDIT: The issue has returned! Arghhh....
