Dial It Down A Bit!

The title says i want to dial it down a bit. and by "it" i mean this http://www.airsoftgi.com/product_info.php?cPath=139_186&products_id=5573
Or Dial this Up to 350-360 http://www.airsoftgi.com/product_info.php?cPath=139_25_151&products_id=2406
It shoots very hot, 400+ FPS, and thats too much for me and i don't want a different one. what i want is advice on how to dial down the speed and be able to do it myself. Btw-I haven't ordered them so all of this is for future reference.

I haven't heard of any way to dial down the velocity on gas pistols. Perhaps sticks or LW would be able to help you out?

maybe just put less gas in the mag?

are you using green gan? i was able to bring down the fps alittle by going over to duster gas from "airsoft" green gas i use it for agm m4 which shots way hot to.

This is the reason some event organizers do not allow(and shouldn't allow) Co2 pistols.... They shoot waaaay to hot to be used as a sidearm.

On some green gas pistols you can purchase a lower flow valve, but they are very hard to find. In the good old days everyone just used blue gas....

sticks

Why so dead-set on these two? If you outline exactly what you're looking for in a sidearm, perhaps we could find one that's already in the proper fps range. The only way I know of to manipulate the fps on CO2 guns is to use heavier or lighter BBs, but that doesn't change the amount of force it delivers to its target.

Ok....so far i have concluded that i want the WE tech single stack Similar to the Caspian i have linked at the top.
The reason i wanted to dial down the Co2 1911 is because of its price that it was listed at would have fit my budget and tickled my fancy.
