With pump it is not necessary to have a small hopper or gravity
If already a player then your normal electric or force fed hopper will work fine
However you aren't going to need the features of a force feed, and perhaps could do without batteries
If buying for it then a basic gravity will do but a proto primo (gravity with shelf assist) is ideal
Being a pump player who shoots little does not mean you have to have a small hopper. Instead you could have a normal hopper and one pot or none. Then youre running light on your body
So - any existing hopper, a basic hopper or a mini 50 hopper
