  Oh yes, easily. Methane is a volatile chemical, which means it it’s very, very happy to take part in chemical reactions. A spark much smaller than what you get from a gun would be enough to cause the methane next to it to combust (combine with oxygen, generating heat and light), and the heat from that reaction would set off all the methane next to every other methane molecule, and WHOOMPH, fiery explosion! Bye bye room!
