I've had a rifle in the past, and switched to a pistol. Both were by cap-chur. I like the pistol, much more than the gun. Mine are co2 guns. From reading post here (no first hand knowledge) a pump may be the way to go. I had one failure early on due to lack of power. Since then , I do test fire. If it sounds weak at all, I change cartridges. I will say cap-chur customer support is as good, as I have ever experienced.
