I need some help from some one that has a Sig p229 in 9mm and has a set of calipers for measuring. The reason is because I just got a p228/p229 target barrel for my p228 and it dosen't fit. It seems to have been mis-machined or mis-labeled. The barrel drops in so far that it hits the feed ramp on the extractor. The dimension that i'm interested in would be from the top of the chamber to the bottom of the feed ramp. my p228 is: .830 my p229 .40 is: .780 my p226 9mm is : .833 my new barrel is .782 The new barrel has the thin wall so I know that it's not a conversion barrel.
