The Grub Screw is missing. So if you want that the Outer Barrel wont turn sideways just unstall a grub screw
It fits fine and protects the Reddot.
It is a nice straight trigger. Works just fine
It has way too much play on a 18c because the cutout for the rear sight is too big. It gits perfectly tight on a 19x though
made with great detail, will recommend.
