Can you increase the power of a CO2 pistol? Our guru has the answer
Dear Guru I have a CO2 replica pistol that fires pellets, and although I really like it and it’s very accurate, I want more power. My friend power-tested it with his chronoscope and even with the very best pellet, it only makes about 1½ ft.lbs. I don’t think that’s enough. My other mate has a big, break- barrel, spring pistol in .22 and that hits much harder. What can I do to get my pistol going better? TOM
Hello Tom My experience of CO2 pistols is much like yours in that very few of them make much more power than your own one. However, I’ve never seen it as a problem. Pistols like this are intended for plinking and informal target shooting, and 1.5 ft.lbs is plenty of energy. It will punch clean holes in paper targets and knock down tin cans out to sensible distances, so why would you need more? Also, running at this power you get lots of shots per fill, which of course is a good thing.
I knew several people who competed with CO2 pistols in action- shooting events who tried to increase the power of their guns and never succeeded. One was a top- class gunsmith who tried everything, so I’m pretty confident that it cannot be done without seriously re- engineering the pistol. I say, be happy with your pistol the way it is and just have fun.

Even highly- tuned competition CO2 pistols only make around 1.5 ft. lbs.
