I have a 20 gauge Mossberg 185 d/b bolt gun for varmints, real handy but after I fire it it ejects the magazine a little ways, and wont pick up the second shell unless I hold it in,which aint no big deal really,just thought someone might know if its the magazine catch or the magazine. I found some nos mag catches thought bout ordering one.maybe a new mag.just thought I would fix the old girl.
