BLADE-TECH MANUFACTURES SPACING SHIMS AND IS A FACTORY PART. IWOULD RECOMMEND CONTACTING BLADE-TECH AND PURCHASING SOME SMALL RUBBER SHIMS THAT ARE USED WITH TEK-LOKS. I BELEIVE SINCE IT IS A FACTORY PART USPA MAY POSSIBLY ALLOW THAT IN PRODUCTION CLASS. PROBABLY HAVE TO CONTACT USPSA. OR ANOTHER FIX WOULD BE IS TO HEAT THE DROPPED ATTACHMENT AND CANT THE FIRE-ARM AWAY FROM YOUR BODY. I DO NOT RECOMMEND DOING THAT DUE TO THE FACT THAT WOULD VOID YOUR WARRANTY. BUT IT WOULD WORK DON'T HEAT IT TOO FAST WORK AT IT SLOWLY.
