I’m relatively new to firearms. Bought a P322 as my first pistol last March and have shot about 2000 rounds at the range mostly CCI of various types. The slide consistently failed to lock back after mag emptied. Sent it back to Sig. It just came back. The gunsmith repair note states: “Replaced mainspring and hammer strut seat. Dressed and polished barrel chamber mouth. Adjusted slide catch lever.”
I’m guessing the hammer strut seat was the and the mainspring were the components which caused the failure of the slide to lock back. Why did the gunsmith “dress and polish the barrel chamber mouth”? Was he just doing a nice extra since the gun was at his bench, which is my uneducated guess, or did the barrel chamber mouth have anything to do with the slide failure to lock back?
I’m taking it to the range tomorrow night to see if the function has improved. All comments welcome.
My guess: The chamber mouth was a tad tight and may have restricted (or slowed down) the extraction of an expanded case enough to keep the slide from retracting enough to engage the slide lock. Possibly done in conjunction with the other fixes to fully address the problem. Wild ass guess...

This. If I were a busy gunsmith doing warranty work for a major company, I would address every possible cause (within reason) while the gun was on my bench, rather than going through the tedious process of fixing and testing and fixing again and testing again, etc.

Quite a few of these had light strike issues right out of the box necessitating a hammer spring shim, or swap. Most of the time the repair dude swaps out anything that may be related to the problem description. Sounds like they did what is typically done. Switch some stuff and send it back. Hopefully they test fired it. You are likely good to go.

The slide lock back was just the catch adjustment the rest was to cover other common issues so that you end up a happy customer and have a like new operating pistol.
