Good match narrel - ZEV Technologies Match Grade Barrel for Glock 34

I purchased this match barrel to see if it could improve the already good grouping of my G34. The first thing I noticed was the fit when I dropped it in the slide. The factory barrel had the slightest bit of play which is typical of a factory Glock. This barrel had none at all and dropped right in.
On the range, the barrel functioned flawlessly. I saw a very slight improvement in group size using the same ammo, but I wasn't complaining with the factory Glock barrel. After approximately 300 rounds during that first session, I removed the barrel and cleaned it. The finish on this barrel was not worn at all and cleaning was very easy.
I would recommend this product if you want to see a slight accuracy improvement in an already good pistol. Cosmetically this barrel also looks great in the pistol.
