Have a P211GTO. Running perfect. Came with metal plug. Zero issues with over 800 rounds through it.
Easy to clean barrel with comp attached.

The issues I read about with it is the removal of the comp assembly. Parts are lost or it comes loose.

I swab out the comp with a qtip but does it actually need to be removed? Don't want to cause any issues.

There is no real reason to remove the comp for cleaning.

I am at 3400 rounds and have yet to remove mine. I did add some anti-seize when I first got it
