Adjusting velocity on Sterling STP

I purchased a Sterling STP from a user on this site a while back, and I'm just now working on getting it ready to play. I took it out and it shot beautifully, but a bit hot at 314 fps. I went to adjust the velocity according to the directions I've seen online and guess what? No hole in the pump handle to adjust the velocity. I did see that some models had to adjust the velocity by changing the main spring. Is that the case here? Is there another way I can do this, like adding a regulator somehow? I will try to include a pic of the model I have. Thanks for your help!
