Question, I have the Maximus, and the only fault that I have is in the trigger, could that be the spring. Cocking is a little tough is that the spring. As far as shooting groups, and ease of filling I think great buy for the money spent (to get into PCP). Now would love to step up to a Marauder .
The valve was moved back which is one reason for a shorter spring.The Maximus is OK but you get what you pay for. Had mine 2 days and sold it.Norm
