Fired the brand new 29SF (serial NGD) today and had 3 malfunctions in 100 rounds. 80 rounds fired were 175gr Winchester silvertips, 20 were Buffalo Bore 180gr. All malfunctions occured with the Winchester ammo. There was a failure to feed properly and the slide was stuck back about 1/2-1". Personal error? Faulty ammo? Faulty gun? I've tried sifting through the info on the G30SF issues, but there doesn't seem to be nearly as much in the way of the 29SF (as expected).
