I’ve been having problems with my Kimber’s magazine release for a long time now. Sometimes, the magazine never ejects completely and does not fall freely. This problem is hard to troubleshoot because it happens only occasionally. It’s frustrating when it happens during a match because that can cause me up to a second during reloads. Thanks to a brilliant & fellow shooter, Emanuel, he recommended that I take a look at my mag release, namely the left part of it. Sometimes, if you press really hard (not hard to do while shooting a match because of adrenaline), the left part of the magazine release protrudes out of the frame of the magwell and holding the magazine up.
Here’s a pic of the magwell at rest :
and if I press it really hard :
The fix? dremel around 1mm of metal off from the left side of the mag release, and test it in the gun for fit. Once it fits, polish it so there won’t be any hangups.
