Hi all,

Just found out today, as I've been comparing the rifling between mine p226 and my friend's.

His, with AH (2007...presumably) marked on the side seem to have much deeper grooves in the rifling and much more "complex" looking.

Mine however, with BA (2010) seem to have simple, and really really shallow groves that looks kinda almost flat...

I haven't tried the two pistols yet but according to the test fire on the factory sheet, both shot excellent groupings. (co-incidentally by the same guy...)

Both pistols are bought second hand with around 100-150 rounds through it..(so saids the seller), but my friends (2007) has significantly greater ware than mine....yet the rifling is still deeper.

I was wondering is there a reason why this is? Perhaps Sig used a new material that's harder and more durable so the groves does not need to be that deep?

Any insight on this would be appreciated....
Thanks so much!!
 
there should be sharp, I bought a Sig a few months back and rifling was nicely defined. That is something I look at eveyr time I get a new pistol after buying a SW MP that had almost no rifling, I am not kidding, it was flat on one side.
Bottom line, I don't buy pistols with regular rifling anymore, all polygonal.

By any chance, do you happen to know if the 2007 gun was sold as a new gun, or as a factory refurbished gun?

I would assume the 2010 would have been sold as a new gun, but if it was a re-furbished gun, this may explain the difference in rifling.

That's all I've got!

Edit: Relied on my old memory on type of rifling Sig has, just had a look down my Sig, HK and Glock barrels, no polygonal rifling in a Sig barrel!

"Never mind!"

My 226 is only about three years old, I have regular round rifling, although it does look abit shallow. I thought GLOCK was one of the few manufacturers that supported polygonal rifling?
 
I never heard of Sig having polygonal rifling. Maybe the early ones? If you question your rifling, I can tell you that those 200 rounds shot previously didn't affect the life span of your barrel. I shot more than 15,000 rounds tru my P226 and the rifling still look like new.

I wouldn't shy away from regular rifling just because of your experience with the M&P. Smith & Wesson has terrible quality control. Every recent production (i.e. post 2000) S&W I've ever bought was defective in one way or another. I will never buy a new S&W again.
 
I agree with you. I also noticed that I mistakenly wrote hexagonal for polygonal. It has been fixed now.

Never heard of Sigs with polygonal rifling either.
Only pistols I know of having polygonal rifling are HK and Glock maybe Walther, although I am sure Walther is mostly regular rifling.

SIG USA out sources most of their parts, so different company's different barrel styles. I have shot all kinds of SIG USA and German SIGs and they all shoot the same :)
 
The other thing is the German made Sigs all have pressure tested, stainless steel barrels which are not chrome lined… The US made Sigs do have chrome lined barrels. They definitely can appear different, looking down the bore.

Standard German SIG barrels are not Stainless and SIG USA Sigs are not chrome lined

It's the way to go. All modern HKs are like that, along with all glocks. it works. The end.

Wow... Wrong info told to me by a guy that's been at SIG for over two decades.
So... which Sig bores are chrome lined?

Tell him the canadian military sig barrels are all not chrome linned and all of the SIGs i bought civi side were not chrome linned. Maybe SIGs QC dept really crap the bed on that one lol :p I am a factory cert sig armourer btw and been working on sigs for 10yrs. I do know beretta chrome lines their M9 pistols.
 
How do I tell if my barrel is Chrome lined or not?

both the sigs are not polygonal rifled, but just the 2010 one has a much shallower rifling, I'll attach a picture of the two for comparison soon!

Thanks!
 
The four German Sig's I own, have stainless steel barrels...
none of which are chrome lined.
My Colt AR H-BAR 6601 is not chrome-lined and is "the most accurate"
rifle I have ever owned. I guess if I were in Iraq or Vietnam, I
would definitely prefer a chrome lined bore, tho.
