Gunsmith then takes the gun away, but tells me to keep the magazines, which I did.

Sigh ...

The smith should have sent the magazines too. I would give Sig CS a call and let them know about the problem. Offer to send the mags in directly to them so they can test them.

Your first and last photo show the problem. The case rim is sitting on top of the extractor claw where the extractor claw should be over the rim. That pistol is really clean so the problem is not your cleaning skill.

Based on the pictures, my guess is pistol could be short stroking. That would be caused by not enough bang in the ammo or by too strong a return spring. Since the pistol's problem happens regardless of the ammo you used, the return spring would be the suspect if the problem is short stroking. However, the problem could also be the extractor tension or geometry. Either way, a call to Sig customer service is in order.

Youtube can be your friend. If I linked this one right it will start around 3:32 of the original video:

Ignore the polishing the feed ramp part at the beginning.

I'll give it (yet) another good clean and now a SUPER LUBE. I'll likely get a chance to shoot on Tuesday, and will report back if rounds 176-275 are better, worse or the same.

Wish me luck!

While you are cleaning ( or, were, as the case may be), remove the firing pin stop and pull out the extractor for inspection. Be certain to get rid of any carbon in the extractor claw. Make those rails extra greasy

My 238 has a flat spring and has never had any ejection problems. I use Super Lube and keep the rails on the greasy side:



OTOH, I have had other guns with ejection issues. Most of these issues were either related to the ammo I was using or the extractor.
