Kwa M9 PTP spring
 

Hey guys,
Frist of all i tried to search this but i couldnt see it so im sorry for bumping an old theard!

And i was just wondering i know the KWA M9 PTP shoots pretty hot and sod does everyone else but this could be a stupid question and pretty simple answer but if you wanted couldnt you just get a lower spring for the gun so it doesnt shoot as hot ? or could you make any other small upgrade to the gun to make it not shoot as hot?

Spring swap to reduce velocity works in AEGs only, or spring powered pistol/guns

It's not going to reduce velocity at all with a weaker spring; you're most likely prevent the slide to cycle properly, or it will make it take longer to complete a cycle

short answer: no.

A different valve in your mag would help, but I doubt there's any that would allow you to do exactly that actually. I'll let other pitch in their ideas as I don't have any viable solution in mind.

okay pefect!
i knew you could go AEG's and for spring guns but i wasnt sure about gas guns! and i know about Npas kit or Npas mags that you can set the fps on the mag atleast i think that it how it works!

was makes a replacement nozzle that lowers the fps approx 25fps. and I havent found anywhere local that sells it or other replacement parts. my m9 pro shoots 284 with 28s or approx 325 with 20s.
