So I'm in the market for one of these on my UG P-09. From the official website I get that I need to get one of these booster assemblies for the P-09 to cycle properly. Did I get that right?

There are two to choose from: 1/2×28 and M13.5×1 LH. Can someone help me understand what this means and which one I should be getting?

That is the thread pitch, standard or metric.  What are the threads on the end of the P-09 UG, 1/2-28?

Usually, "M" is for metric.  "LH".......left hand maybe?

My guess is that it will be 1/2-28 if here in the USA.

Does it tell on the box what it is threaded?

The CZ UG threaded barrel is a 1/2 X 28 tpi thread. I didn't realize that a booster was required if you are shooting NATO rated ammo.

So is it required? I just assumed it is to cycle properly. I'd be more than happy to save the extra $150.

Can anyone with a suppressor on their P-09 shed some light on if a booster is necessary??
