Budget Co2 pistol - pull trigger + bb comes out
nuff said
gas - CO2 or Green Gas stuff can suffer from cold but think you are ok where you are
basic pistol to get ya started, but if you are happy and it works ok in 6 months time
that is what matters - yeah not top of range but ok to get started with
if you are lucky - see if it can take both CO2 and Green Gas mags to give best options
GG mags can use propane gas to save money but need adapters etc....
so extra cost but long term savings if use lot of Green Gas
