Having trouble with barrel swap. Sig P229

[Mythdragon]

I bought the Sig P229 Elite .40 cal.

I just bought a Sig (factory original ) 357 sig barrel.

However, when I install the new barrel the slide will not fully re-attach. It catches right where the takedown lever lines up with the slide-catch grove.

There are now dents and scratches on the bottom left and right sides of the feed ramp. Almost as if the feed ramp bangs against the slide somewhere.

Near as I can tell (aside from the barrel diameter) both barrels are identical in size. Side by side, I cannot see any obvious flaws. Why would one work, and not the other?

Is it more likely a bad barrel or a bad gun? And here I thought Sig was hi quality.
Appreciate any help.

I don't think it's a bad barrel or a bad gun. Most likely, the barrel will require some "fitting", from what you describe. I know on a lot of the custom barrel makers websites, you have to send the slide in so they can match the barrel to it.

I just speculating, but the 229's that come with both the .40 barrel and the .357 barrel were probably both tested to fit, or built loose enough that some minor tolerance issues wouldn't prevent the barrel from dropping in.

I'd call SIG, if its a factory barrel, it should drop right in without any issue.
