Picked up a 11/16 produced P320 SC a few weeks ago and thought I'd share a few things. It came with 2 twelve round USA made mags. Thursday I picked up a P250 SC mag from the local pawn shop for $20 that's Italian made.  The Italian made mag has a finish that is smoother and not as thick looking as the USA mag. The USA mag that I've been using the last couple weeks is already down to bare metal in several places. The USA mags do load easier for me which doesn't sound like the norm. The floor plate on Italian mag is molded a bit cleaner with the SIG marking more crisp.

Also just noticed that the holster that SIG includes must be old stock and is marked for the P250.

I don't expect trouble from any of them. I'm going to put more rounds through the Italian mag to see if it loosens up.

Polished one of my reluctant mags with car polish and a buffer.  Now it drops free with no problem.
