Why Would You Want a New Barrel?

You might need a new barrel for a few good reasons. You might need a barrel as an upgrade from the stock or factory barrel that initially came with your M&P Shield. These barrels usually won’t hold up their end of the bargain. If and when that happens, you’ll know its time for an upgrade. Here are a few reasons why a new barrel may be the best route to go with:
