I think the policy may depend on the airlines, but I've flown on American (4 times) and Delta with no problem with a vest using a CO2 crtridge for inflation. American even has a written policy that explicitly allows life vests and, I think, paintball guns, to be carried in checked luggage.
Ryanair's web site states no firearms carried in baggage "for safety." No wonder you dislike the ba-----s.
Southwest Airlines in the US, after which Ryan has patterned itself, readily accepts firearms and ammuniton, and CO2 cartridges, as baggage.
Following is the Southwest Airlines CO2 cartridge policy from its web site:
"Self-inflating life vests or personal floatation devices equipped with a CO2 cylinder and one spare are allowed in checked baggage. The Transportation Security Administration (TSA) prohibits them from being carried onboard."
