In a range session of 200 rds, the pin (supplied by Grip force) moves to one side and the beavertail comes out of one side, or the pin starts bothering on one side. I have to stop, pull out the glock tool and push it inside. It happened 2 times in 200 rds, also happened in the last session. I liked the beavertail, but took it out today. Does anyone else had similar problem ?
