So I got my threaded barrel installed in my P320 Atac but the pistol doesn’t cycle. The slide is not going back far enough to eject spent case or pick up the next round. The pistol runs’ fine without the can (Dead Air Ghost 45). My CZ P07 runs just fine! Using 9mm Subsonics.

So I’m thinking too much recoil spring. Thoughts?
Thanks!

Does it have the Nielsen device in it?

It has the spring and slider for it to go on (not sure of the name). The 320 is the only pistol out of 5 that I’ve had any issues with.

Just went and looked at site. They just call it a piston & spring. Different ones for 1/2-28 and .578-28.
