Handgun Barrel Rifling
 
Could someone explain the difference in polygonal and conventional rifling in a handgun barrel?

NGIB 02-03-2010 02:07 PM

In conventionally rifled barrels the grooves are cut into the barrel. The drawback to polygonal barrels is that you can't (or shouldn't) shoot non-jacketed rounds...

Thanks NGIB, that's what I'm looking for. You had mentioned on another thread to me and suggested a Kahr PM9, and their specs on the barrel is a polygonal rifling. That's why I was asking. I didn't know the difference. Would you consider it to be a problem or concern?

Not unless you intend to shoot non-jacketed ammo. The Kahr PM9 is a great little carry gun, a tad pricey but nothing good is cheap...

Generally Polygon rifling is hammer forged into the barrel. Conventional rifling is cut from the barrel surface. Polygon rifling can allow higher velocity because of the lower friction. Polygon rifling is less disruptive to bullet jackets. It is also MUCH harder to compare bullets because of the minimal markings left on the bullet.

Is the thread officially killed yet.

Between you and crossfire, I'd say this one's toast...

Yep, its dead, you guys killed it. Thanks.
