The suppressor is made of steel, and thus, unlike suppressors with aluminum internals, the life expectancy is many thousand rounds. I don't know exactly how many it can take, but I doubt I will wear it out in the foreseeable future.

As for impact change, with this load it is virtually the same with or without the suppressor. However, if I add more modules, than the POI does change a little.

This light load is both pleasant to shoot, and more importantly for the moose meat that I sell, it creates less blood shot meat.
