Hey yall. I have owned my factory certified pre-owned (red box) Sig P320 Carry model since fall of 2019. The pistol has a born on date of October 2018, based on the markings present on the grip module. It has all the factory upgrades from what I can tell.
When I purchased the handgun, it appeared as if it was unfired, with no wear present on the barrel or corresponding areas. I really enjoy this gun much more so than previous Glocks/M&Ps that I owned. My one concern is steel case ammo. I understand Sig does not recommend steel case, as do most manufacturers. I ran tons of the Tula and Wolf steel through my various Glock 19s and M&Ps over the years and malfunctions were almost non-existant, but would have from time to time.
Since purchasing my 320, I have put in the neighborhood of 4-600 rounds through the gun, with approximately 60-70% steel case and the rest brass. Every time I go to the range I notice a handful of malfunctions with steel case ammo, all of which of some form of failure to eject. Most often, the handgun will fire, and the slide will lock back with half of the spent case hanging out of the chamber. This is always easily remedied by removing the magazine, working the slide and returning the magazine to continue firing.
My 320 has never experienced a failure with brass case ammo of any type. I am just wondering is it the ammo, the gun, me, or a combination of all three. Any input would be greatly appreciated!
