Walther p22 5" barrel set - Walther P22 Long Rifle Barrel Set, Stainless Steel, WU-BPI-512506

Excellent quality. Super easy to install, and the extra length does help with accuracy. My only complaints, if you want to call them that, are: 1. this barrel, and the P22, are not actually made by Walther; they are made by Umarex to Walther specifications and, although of good quality(especially compared to earlier versions , non-Q, of this pistol), you shouldn't expect the longevity and performance of weapons such as the PPQ or Q5;
2. the device at the end of the barrel is not a compensator; it is a barrel weight at best, nothing more. I may be a perfectionist, but I can not stand see the advertisements call it a compensator, or hearing people refer to it as such. But, aside from those minor issues, I am very pleased with it. I had around 2000 rounds through the gun before the addition of the barrel, and I look forward to several thousand more.
