I guess the answer to the first part is a resounding NO. There are a lot of Silencer manufacturers out there. Seems like his will come around soon. Looks like a quality can.
With all the hoopla on other sites about them, I was curious if someone here has shot them and their opinions are on them. I would trust opinions here more so than from those other sites. They do seem like nice cans.
I've shot them considerably. They have a nice tone and I really like the mounting system. If you need maximum suppression, the Sandman L or Sandman Ti ( direct thread) are my choice. If you are willing to give up sound reduction for a shorter can, Sandman S gets the nod.
