I'm getting this pistol http://shop.ehobbyasia.com/pistols-gbb-smgs/tokyo-... and I am not sure whether to buy 2 extra mags or a laser grip and one extra mag? Here is the laser grip http://shop.ehobbyasia.com/catalog/product/view/id... Just an extra thing the pistol is fully automatic so I would use a lot of ammo. I do have a speed loader but I'm not sure if the mags hold enough gas in one fill for 50 bbs
