If you want to save money on gym membership use a hand pump. That are small and after your exercise it can be easy to store.If you want to fill your air rifle save for a compressor. Or look for a friendly shooter who has one and is willing to fill a tank for you.If you canít find a way to get HP air without killing yourself I would stick with springers.
the seneca aspen is starting to look better to me , Co2 also for that matter. the hand pump is like another hobby or chore.
Stretch, I think the idea of putting water in the pump was half baked mod from one vendor of these pumps. Neither the G6 pump they copied nor any of the other vendors of this cheap pump use water. Straight water is not a proper lubricant, even though it may cool the pump a little. Try running with just a couple drops of silicone on each o-ring and I think you will be impressed.
