There is no difference. Sometimes a supplier will have a sale on an item, and the price is better than the L.E. only price. It happens all the time.

no difference buds prices are controlled by computer program and sometimes it causes some unexpected good deals here is what buds says about prices
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.”

Adam, the pistols are the same. Nothing different. Buds prices are tied to stock level and this can and frequently does make the non QP model priced lower when it has higher stock. This is a common occurrence since the QP firearms carry lower stock numbers on average.
