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.

Cor­rect lu­bri­ca­tion is vi­tal to full per­for­mance
