I just received mine today, but I have to get my paperwork sent out so I can take actual possession of her. I did get to shoot a mags worth of subs and it is definately a lot louder than I expected. Barely hearing safe. Over all the fit and finish is amazing. The actual suppressor is very small. It slides over the barrel a good 2 inches. My buddy's H&K MP5 9mm suppressed with a Thompson Machine Isis-2 (a much bigger suppressor) shooting subs is a lot quieter.
