My new .45 ACP P320C suddenly stopped going into battery. I suspected my reloads were at fault but even the Sig Elite V-Crown rounds are holding the slide open. I've shot 20 rounds of the Sig ammo and 60 rounds of 200 grain Berryman FTP and 4.6 grains of WW231 before this occurred. I dived onto the web and this is a common problem with the gun. While researching remedies to the situation, I learned my gun was not eligible for the Sig upgrade for the trigger and disconnect replacement and modification offered a couple of years ago. Looks like it was a late production gun that had the mods applied before shipment even though the trigger is the wide version. I think I'll call Sig to see what they think.
