Spike's Tactical Billet Trigger Guard Gen II, Black Finish SLA0102 The Spike's Tactical Billet Trigger Guard Gen II is a drop in replacement trigger guard that's styled after the Spike's billet lower trigger guard. The extra room that this billet trigger guard provides is excellent when using shooting gloves or even cold weather gloves. It also fills that annoying gap in between the standard trigger guard and the front of the grip. The front of the trigger guard has a spring loaded detent much like a mil-spec trigger guard. The rear uses a solid cross pin with a groove machined in the center. A captured spring in the trigger guard itself makes installation as easy as aligning and inserting the pin. A rubber bumper built into the trigger guard eliminates any rattling.
