Broach and button rifling is the same thing..........the other method is single point cut rifling.........unless you are talking about factory hammer forged.
Sorry forgot about polygonal

A broach cuts metal a button swages it.

Sorry forgot about polygonal Polygonal is a shape, not a manufacturing method.

Polygonal is probably cut using a broach.

It is buttoned (Schneider) and hammer forged as well.

what I am looking at are the aftermarket barrels for a Glock G20 6" and not sure which one to go with..looks like the rifling is diffrent. So thats why I ask if one is better then the other:
EFK Fire Dragon( rifled using Electrostatic Discharge Machine process)
KKM Precision (unique Button Rifling process)
LoneWolf(�Match grade broach cut rifling )
Stormlake(cut broach rifled)

CMIIW, but I don't think it makes a whole lotta difference for pistol barrels. I'm not an IPSC shooter, so I haven't burnt out more than one pistol barrel.
If it was a rifle, you'd likely get better life with broach cut.

If you are after accuracy I'd go with the KKM barrel

Sorry forgot about polygonal Uh, not hardly. A broached barrel, such as (was) done by Thompson Center is where the rifling is CUT by a single pass of a very expensive broach (a cutting tool that incrementally increases in cross-section) whereas button rifling swages, for lack of a better word, the rifling into the smooth bore by pulling or pushing a hardened button with the negative image of the rifle ground into it. The button simply displaces metal, the broach cuts it away.
