Just wiggling the mag in its locked position should not cause a release. I tried wiggling my magazines while locked in the gun, as you describe, but couldn't get either to work loose. Both stayed locked in place. Sounds like you have an issue for customer service. BTW, both of mine have the pinkie extension. I tried the mag supplied with the BG, as well as another S&W supplied mag that I bought recently. HTH's Rod
