Highly recommend the trybe barrel - TRYBE Defense Smith & Wesson M&P Shield Match Grade Threaded Pistol Barrel

I am a competition shooter and obviously I'm not shooting my shield for competition but I like to practice with it quite a bit as it is my carry weapon. I shot it. Probably 500 rounds with the stock barrel in it and then I have shot. Probably another $500 to 1,000 rounds through it with the tribe barrel through it. And I can tell you right now accuracy and precision is amped up quite a bit with the tribe parts
