The Tippmann TPX Pistol is the newest addition to a lineup of superior, dependable, and affordable paintball markers. The Pistol is one of only a few Paintball Pistols that are .68 caliber. This allows you to use standard size paintballs which can be purchased anywhere. Other manufacturers use a smaller ball which will not have the same breaking impact on your opponent. The smaller the ball the less chance it has to break.
