Your Glock pistol was carefully designed so that it would be selected by the Austrian army. Beyond meeting the criteria required by the Österreichisches Bundesheer (Austrian Federal Army) Gaston Glock’s pistol could have been no better than it needed to be. Its rifles, not side arms that are the basic weapon of the infantry. However, Glocks are not simply good handguns, they are also handguns that can readily improve and modified to suit a shooter’s notion about what a handgun should do.
Installing an aftermarket Glock 19 match barrel is a common modification. Match barrels, with lands and grooves, rather than the OEM polygonal rifling allows lead bullets to be safely fired. Aftermarket Glock 19 match barrels are also held to tighter specs than those used by the military. Military grade barrels are made to handle military grade ammo. Tolerances have to be relaxed to take into account variations in ammo manufactured by companies who obtained their government contracts by putting in the lowest bid.
The True Precision Glock 19 barrel is an alternative to military grade barrels. True Precision broach cuts six lands and grooves in their barrels, giving them superb accuracy with lead or jacketed projectiles. The chamber is machined to fully support the base of the cartridge for increased safety with hotter loads. The True Precision Glock 19 barrel was manufactured in the United States and designed for installation without the need for modifications to your Glock.
