Things I liked: The magnet holds bb's very well it is possible to get 2 crowded into one hole tho so have to be careful with that
Things I would have changed: wouldn't change anything
What others should know: I can shoot 4 complete magazines with 1 Co2 cartridge
Things I liked: Fits perfectly on my Px4 Storm. The laser remains small diameter at good distances (15-20 yards)and led flashlight is really bright
Things I would have changed: The price.... good quality product but I can't find $60 in it.
