Hey folks,

I just picked up a Mk19 in 44mag, but one thing I noticed is that the slide doesn't lock back on an empty mag unless I push up on the magazine as I pull the slide back. This happens with both the factory mag that came with the gun and a second factory MR mag, so I'm thinking it's not an issue with the mag.

When the mag is fully inserted, I can see that the slide lock is pushed up against the bottom of the slide, and there's no play. However, as the cutout on the slide passes over it, the slide lock doesn't move upward to engage; I have to push the magazine up so that the faceplate is flush with the bottom of the grip in order for the slide lock to move up and engage in the cutout.

Has anyone else run into this issue before?
