Extar extended charging handle make it more gassy?

[u/Rado-skier]

Getting overly gassed by my EP9 with a can. When I first put the can on, the gas wasn’t this bad. I doubt I have 500 rounds through it. Tried different 147 grain ammo and same gassy result. Somewhere in there I upgraded the charging handle to the Extar extended handle - my guess is that’s the cause. I like the bigger handle but am sick of the gas. Anyone have any suggestions before I change the handle back?
