I just picked up a SIG P228, and a SIG P239 this week for concealed carry. Today I got a chance to take them both to the range for the first time, and I put about 175 rounds through each one of them.
I had some real problems at first with the 239 every round from the first magazine either had a stove piped ejected casing, jammed coming out of the magazine, the round ejected but the next round didn’t chamber, and after the last round the slide didn’t stay open but the chamber was empty. I switched to the other magazine, and a different kind of ammo and it continued but some rounds started cycling correctly. Eventually I only had a stove piped casing every third round, or so but the slide was still staying closed after the last round ejected. Finally after about a hundred rounds the gun started functioning properly.
I was thinking the recoil spring was the problem, but when I took apart my guns to clean them afterwards the finish on the 239 barrel was worn on top, bottom, and side.

I don’t believe this gun was thoroughly inspected at the factory, and it didn’t have any shell casings included like the 228 did. Hopefully it won’t act up like this again or I am going to have to send it back to SIG.
