Im thinking of buying a 495 fps gas non blowback postol. Will this be ok to use on the field?

Its a asg steyr m9-a1 it chronos at 495 ish

Pretty sure its a 400 fps with 20 gr bbs. 495 is pretty hot for a pistol and i would bet that was with 12 gr bbs. Best bet would be chrony it with 20 gr bbs or bring it and test it there. If its to fast leave it in the car.

They have a facebook page with rules if this helps do not know the fps limits for pistols sorry
