The metal of the barrel hood is elevated somewhat in the center. You can see it (a little blurry - I tried to sharpen a little) along the front edge of the barrel hood. I drew a line with an exaggerated hump illustrating where it is elevated. The wear is significantly uneven. I doubt very seriously that any shop sent the gun in to SIG for examination prior to selling it. I would contact SIG and send them a photo. They may want to fit a new barrel to it.

I just re-examined the barrel, I think you're correct, it def does not look even/flat across the top. I'm going to try a new barrel, it if still shows signs of wear, I'll send it to Sig.
Thanks again to you and everyone that responded.

I would agree that the barrel hood shows some unusual wear patterns, but I don't think, in and of themselves, they are anything to be concerned with. The top flat of the barrel hood really isn't a critical surface in terms of function; it doesn't fit up to anything and just slides under the slide and back up as the pistol cycles.

Admittedly, it not the most pleasing look but for the price you paid I would not replace it just because of the wear. Keep the barrel, barrel hood, inside of the slide greased and shoot it. The important thing is whether it runs well.

If you have a flat plate (granite block, even a granite kitchen counter, or a piece of thick plate glass etc), you might put a bit of 320 - 400 wet dry on the flat and take a few swipes to clean up the surface and show the high and low spots. To my understanding, the barrel hood (upper surface), as the barrel unlocks during recoil, cams down and out of the way though most of the slide's rearward travel. It is only in the latter part that the hood rubs against the underside of the slide.

Polishing things up, and lubricating those rubbing parts, all may function acceptably well.

Maybe.

Or not.

The wear on mine is smooth and mirror-like. The unevenness on yours looks unsual. I have been shooting mine pretty greasy for the last 20 + years. I suggest running it for a little while longer, with good gun grease on it. You might have an old barrel that someone ran really dry.

Congrats on your P229! Sounds like you've bagged a great pistol at an even better price!! You haven't mentioned how this pistol shoots. Am assuming that means it's reliable and accurate.

The barrel hood looks like it's been run too dry. IMO, the wear is cosmetic and easily cleaned-up with a light polish. Take care not to remove any material along the front edge on the barrel hood.

This front hood corner & slide union are the important lockup point where you want to maintain sharp 90degree corners for reliable cycling.

My carry weapons get light gun oil on slide rails, barrel & inside the slide where barrel hood and muzzle rub. For range time where we're busting 100+rds downrange, these same points get a generous grease job. This approach will keep these friction points almost pristine.

Enjoy your 229 - It's a great weapon!!

Cheers

To confirm this, and assuming you don't happen to have a bottle of DyKem (lay out and fitting fluid handy), put a light coat of oil on the underside of the slide where the barrel hood will rub. Assemble and rack the slide once. Disassemble and check transfer pattern of wet oil on the barrel hood . . . this may give you a clue as to whether or not the barrel was swapped out.

Otherwise, lube it all up, the barrel gets grease all over (after assembly, wipe off what's visible). Run it.

Polishing the the top of the hood is an option, doing so will not have an adverse effect on function, lock up, or accuracy.
I'm leaning this direction as well. For whatever reason, SIGs seem to be pretty tight in this area... if the barrel lug and locking block are just a little closer than most due to tolerance stacking, there can be substantial friction in this area of the barrel hood. For example, I once shot a brand new P229 with no lubrication in this area and it literally froze solid with the slide part-way retracted during the recoil of about the 4th round through the pistol. I needed a rubber mallet to un-stick it. After it was properly lubed, no problems. Additionally, the corner edge on the slide sometimes is very sharp; and it can scrape along the top of the barrel hood causing accelerated wear. Another example is when I bought a caliber X-change kit for my P226... the slide would barely go on and it wouldn't fully close unless the slide was slammed home. I had to fit the barrel a little to get it to function 100%.

I wouldn't jump to the conclusion that someone was screwing with your gun or that there is a problem with it. Personally, I'd gently break the edge on the slide with a stone and lightly polish the barrel hood... then fired the gun while keeping it properly lubricated. If there isn't a functioning issue, I don't know if there is anything to worry about.

Thanks!
I just took it out and ran 150 flawless rounds through it. It came with 4 mags, all worked great as well. Still has sig accuracy, so I may just keep it well lubed & hold off on buying a new barrel.

Just FYI. SIG barrels are tougher than nails. I would just grease it up and shoot it, watching for excessive wear on the slide as well. The photo below shows how accurate my 229-40 is after approx. 30,000 rounds. They'll take a lot before they wear out.
