Howdy, I am looking for a replacement barrel to squeeze out any more mechanical accuracy from a Glock 19 (Please no ammo/training comments ). I would assume by having a hand fit barrel I may loose the inherent reliability the Glock has, and thats fine, but is there any barrel out there that offers more accuracy while still remaining as reliably as factory? If anyone can offer any suggestions as to which would be the best, AND which would be the best value Id appreciate it. Im looking for something corrosion resistant, so Id want a stainless barrel. Lastly, would the factory Glock barrel benefit by being re-crowned?
