I am the benefactor of one of these in a trade. It is the suppressor ready model.

I was excited to use it w/ my suppressor.

The short version is, without the can, it shoots great. Put the can on it and the slide will not cycle. My instincts tell me this is a recoil spring issue.

With all the great and smart people on here, I bet someone has experience and / or someone can tell me what I need to do to resolve this.

Thanks in advance!

What ammo are you using and bullet weight?
I had an FN that would run all ammo with one spring but not the other with the can on.
I have a buddy with the same CZ as you I’ll give him a yell.

Nframe - I am using GECO 124 and American Eagle 124

Neither would cycle the slide.

Thanks for asking your fried.

Hey.
He says with his suppressor he can use a bullet weights. 115–147 it may have to do with the can in your case?
Do you have any 147 grn ammo? I’ve had the best luck with that weight and it is quieter.

Do you have the correct piston (Neilson device?)

I am using the one that came with my can.
