Picked up my used P99AS and ran a couple hundred rounds through it in order to test it out along with the supplied mags and aftermarket MecGar mags I bought for it. Didn’t do anything fancy with it. Just mostly slow fire at 10 yds. Found the rear sight needs a touch of windage adjustment. Didn’t get a chance to clean or lube the pistol before the range session, so, ran it dry for the first couple hundred. No hiccups.
