I have a gen4 glock 30 and an IWB crossbreed holster. I carried it for the first time tonight and after getting out of my truck I noticed that the mag was loose. So I started messing around with what could have happened. I noticed that whenever I sit down the gun pushes toward my body and the magazine release button is hit. I carry at the five o'clock position and I found that if I push the handle/grip of the gun toward my body with any amount of force it pretty consistently hits the magazine release button. I absolutely love this gun but if this is a gen4 issue, especially one that's not fixable, then it's a deal breaker for me and I'm looking for a new gun or maybe a new holster. Does anybody else have this problem? How do I stop this from happening? Are there smaller magazine release buttons or at least shallower ones?
