In an effort to begin our adventure in suppressors Niki and I wanted to begin with strong and reliable barrels. We chose to purchase our barrels from Midway USA because of price and customer service. This barrel comes with a metal thread protector that is thin and strong. Even though the thread protector is thin the serrations make it very easy to add and remove from the barrel. This barrel has also made my aim more accurate. A few have told me this is only in my head, but while that might be I feel this pistol handles better with this barrel.
