I purchased an Osprey 450 along with pistons for ,45 and 9mm as well as the fixed barrel spacer. After an obscenely long wait for my stamp, I could not be more pleased! I can now shoot comfortably without addition hearing protection; even indoors.
This suppressor looks natural on my FNX .45 Tactical and it turns heads at the range! It's eccentric design lets me co-witness my holo sight with the iron sights. If I should ever have to defend my family and self, I know that it can do it without permanent hearing damage.
If you buy only one centerfire pistol suppressor, make sure it is this one!
