I had stripped my Shield down to give it an oiling. However, apparently I didn't notice when I was reassembling it that the sear deactivation lever have flipped back up. Now the recoil spring protrudes from the front about 1/2". And I can not get the pistol to disassemble. Jabbing at the lever with a long skinny screwdriver has been a source of frustration for the last 2 hours. Any suggestions? Or is my problem unrelated the the lever? Thanks.
