Fps increase on a pistol (assistance please)

[cminke]

I would like to be able to travel to and from the united states for games with my guns and the only problem i'm having is having all my pistols not shoot High enough. most are around 310-350. as you are aware the minimum INTO Canada is 366. How can I personally upgrade my pistols (spring?, nozzle?) to shoot the Minimum of 366fps. Please forgive me if I'm out of place of out of line in anyway here. I'm glad to cooperate.
P.S. I will be age verified soon, (18th birthday was yesterday) so any links to websites are okay. but all i require is the names of the parts and the correct guide to installation.
Thanks so much guys. I hope you can help me.

High flow valves, hammer spring and a longer barrel.
Tho i think there is a temporary export paper you fill out and declare everything you bring with you and that should allow you to bring it back in easily

Tbb and bucking will also help. I use a reaps A plus bucking in my g18 and it made a huge difference.

you used a reaps in a pistol? i wasn't aware that was easily do-able

I hope its okay to say this since its not in AV section. But take a look at Toronto Airsoft pistols. Notice how they come with a long inner barrel and mock suppressor?
