Sig Barrels

I wonder why Sig barrels are cut/button rifled. I would've thought that they would cold hammer forge them like Glock and H&K. I like the forged barrels more.

Cut/buttoned rifled is the process they use to cut the riflings in the barrel. Cold forging is the process used to form the rough form of the barrell, then it is machined and the riflings are cut.

I meant polygonal cold forging :uhoh: I just don't like to use that word because polygonal rifling isn't always true polygonal....

Not sure what difference it makes. My SIGS always hit what I'm aiming at if I do my part.

Mine too. Good enough for the SEALS, good enough for me. And the process for making the barrel blank has nothing to do with the process to cut the rifling.

I just like polygonal barrels like Glock. If you look at the two barrels, you can see a distinct difference. The Glock (polygonal) barrel looks like the rifling is subdued and the Sig rifling is very apparent. Furthermore, polygonal barrels typically provide a better seal, improved velocity and decreased barrel wear.

Don't get me wrong, the Sig barrel works very well; however, I would like to see them use polygonal rifling.

Cops don't like polygonal barrels. They are too hard to match ballistics. So I've heard.

Thanks for the link. Interesting information. They're not "forging," per se, so it's not a barrel manufacturing process. Unusual term for rifling, but learn something new every day. Glock makes fine pistols--just not my cup of tea. I like Browning's designs--1911 or Hi-Power for many reasons. Trigger feel being at the top. Still, I'd never knock a Glock. They hit the market at the perfect time with the perfect pistol, although others are taking their market share pretty rapidly--SIG mainly, but M&P also.
