Hand pumps are the #1 method  or system used by air gun shooters for charging their PCP air rifles. And if a hand pump is what you need for your PCP, then check out the 3rd generation Hill Hand Pump. The newest 3rd generations hand pump takes less pumping and less effort to fill a PCP air gun. A lot of dealers have a hand pump for sale and sometimes more than one brand too. But if the Hill hand pump with it's Dry Pac is not included in their line-up, then they are missing the best of the hand pumps on the market.
