I just got my new 5 7 pistol today! I have wanted one for years and finally decided to go for it.
I'm thinking about picking up an EFK threaded barrel for my Sparrow. But I was told by the guy who sells the barrels that the O Rings on the Sparrow get chewed and have to be replaced very often, like at the 200 round mark. If that is the case I am totally not interested in using my Sparrow for the 5 7 and will probably skip suppressing this gun. I really don't want to by a dedicated 5.7 can that i can only use on 1 gun.
So Sparrow owners, what is your experience suppressing the 5 7?
