without having both model numbers I cant answer that with any accuracy but here is what Buds says about pricing From Buds “Our website updates every 20 minutes, 24/7, with our current inventory and replacement cost. We do not price our guns manually based on our cost in each, rather we use a live download from manufacturers and distributors to set our price based on our current replacement cost. As our cost changes, the corresponding website price of each make/model will change up/down accordingly. Although our profit margin remains unchanged, our advertised prices will change frequently, sometimes several times per day

Timothy, Buds prices are tied to stock level and a model with higher stock level can be substantially lower in price than a similar lower stock model.
