So I just picked up a P99c yesterday and quite enjoy shooting it. The gun came with two magazines, one with the finger extension, and one with just a flat bottom(as I assume they all do). Shooting with the magazine with the finger extension is great, however, the flat bottom one just isn't going to happen. Is it possible to purchase just the little extension piece to add to my flat bottom magazine? I'd hate to have to buy a whole new magazine just for that little part.
