Pardon me for posting this if it has been done and I haven't found it on the forum. At the range today, I had the magazine disengage from the catch while firing ( a couple or three times.) When I came home I thought there has to be something I can do. With the right and left grip panels off, I removed the metal catch from its post and popped the head of the release from the left side. To get the metal part that engages the cutout on the mag body to go in a little deeper I took the narrow end of the plastic post that holds the catch button and the catch itself and careful cut the portion of post next to the narrow end to make the narrow end longer ( and therefore the catch to ride deeper against the mag body catch cutout.) After reassembly, the magazine is held more securely. I can't pull it out by hand and prying with a screwdriver (not too hard) between the mag well and base plate of the mag doesn't dislodge it. If it works the next time I'm at the range, I'll update accordingly. Just thought I'd get this out there in case anyone else needs to tighten up their mag release. Thanks, and hope this is helpful.
