For BOGs who have a walther p99, may I know what ammo is your carry load or what feeds reliably in your gun? My P99 seems very choosy when it comes to ammo. I have tried the Corbon 115 grain +P and the Remington 124 grains both hollowpoints. Using these ammo, the slide wouldn't return to battery after a few rounds. It seems something snags inside that prevents the slide from closing fully after a round is fired. Funny, armscor ammo works flawlessly.
