I woke up early this morning and had the bright idea of workong on my Baby Browning. I took the handles off and the pin that retains the magazine catch came ot before I could yawn. I've been working on the Baby all day, searching YouTube and other sites but have found no help whatsoever. Can anyone please help me correct my error? I tried reassembly but the catch flips up to expose the spring and the magazine won't go into the handle.
