Mine's flat, too, and it the beavertail can still get moved to the safe position. This is why some IPSC shooters tape or otherwise permanently hold the grip safety in. I personally don't like deactivating safety features on a gun, so I don't do it, but I can understand it. On the other hand, hammer bite sucks. I shoot two .45's: a Series 70 Gold Cup for bullseye, and a Valtro for IPSC. The Colt has a standard grip safety and the Valtro a beavertail. I never get hammer bite with the Colt as long as I'm shooting it one-handed, but use two hands and the blood flows. Shooting two-handed, the Gold Cup bites but the grip safety works perfectly. The Valtro never bites but the grip safety does lever into the safe position while shooting once in a while.
