Do HK pistols have polygonal barrels?

Josh:

The one I owned back in the 80s did...I'm pretty sure they have stuck with that bbl.

I know the P7 series do...

I think Glock and HK's are the only ones that have polygonal barrels. It's one of their selling points.

By the rude bridge that arched the flood,
Their flag to April's breeze unfurled,
Here once the embattled farmers stood,
And fired the shot heard round the world.

H&K USP's, GLOCKS, and KAHRS's all have polygonal rifling (there are probably others). Reportedly this increases velocity, and increases barrel life. Shake

The very early USP9s had regular land and grooves. Have two of them. Since bought a third with the poly barrel since that is what HK is known for.

A very positive advantage the regular rifling has is the ability to take lead bullets without problems. Polys can't.

Poly gives better ballistics and is more easy to clean; though it is not recommended by HK to use lead; some people including my instructor believe that you can use lead, but should run some FMJ after lead and clean more carefully.

There was a very extensive discussion on this topic including using jacketed after lead. Goto to :

The thread has been closed as it was getting pretty long.

Glock's have Hexagonal barrels

Triangle=polygon, pentagon=polygon, HEXAGON=polygon, octagon=polygon. Poly=many. Shake
