classic valve wont fire?

Something to try ... Assemble the mag without the frame. If you don't have shorter screws around, wrap the body and rail with some tape so it holds together. Try actuating the sear by hand and see if it shoots.

You can also take the grips off and do this.

On off pin is .769
Sear is 2 inches front to back with calipers at this second.

No time on lunch to test anything else.

Oh! Its a factory rail also. Someone had asked and I forgot to respond to that.

If the pin is this long, then it could be your problem. The pin should only be 0.750".


The mag with a level 7 should fire even if the pressure/velocity is low. Not firing is typically an issue with the front chamber not getting any air. Since you do feel pressure on the trigger, that is an indication that air is available at the on-off. Therefore, it sounds like an on-off issue where the pin is not clearing the top oring when the trigger is released.

The other issue would be if the bolt is stuck. You can check this by putting the valve into the mag without a bolt spring on it and don't add air. Hold the trigger, tip the gun forward and give it a bang on the back or side of the valve to see if the bolt will slide forward. If the bolt moves freely, then you know its not a bolt issue.

At the dentist now. I will check this out after they give me a new filling.

It works!

Filed the on off pin down to the .75 speck. Works like a top. Thanks guys.

Oh! Filing that little hard pin down kinda sux. Not much to grab ahold of.

Woot! Glad it was figured out. Now go play and have fun.
