After 1200 rounds it has been sent to Sig for service.
I was having jamming problems from the start, many suggested limp wristing was the cause. I added Talon grips and spent time with trainer but still jamming. By jamming, I mean the spent casing was stuck in the barrel. Sometimes I needed something pry the casing out. Sig customer service said it's normal and a 1-2% failure is well within normal range. I find the % to be higher than I would expect. It was suggested to put more rounds (1000+) through it. I was also told that limp wristing was what causes the casing to be stuck in the barrel.
It's very frustrating shooting a gun that jams that often.
Meanwhile my LGS had a sale on M&P Shield, so I picked one up for $319. Having been in manufacturing for over 30 yrs it was clear the Sig is built much better than the Shield, the finish and quality of build between the 2 was clear. I was worried that if I am limp wristing with the P320c, then a smaller gun will be even worse. Nope, not a single jam in 350 rounds through the Shield.
I spent time shooting them side by side, if the Sig jammed, I ran the rest of that box of ammo through the Shield with no problem.
Finally the Sig trigger wouldn't reset. I had multiple RSO's look at it and they said it's broken. The LGS checked it out and said the same thing and shipped it to Sig. They said Sig will likely charge me for the repair and shipping. Great more $$.
Did the jamming cause the trigger problem?
Yes, I did clean and lube the gun prior to shooting the first time and after every time I shot it. I also was told that "Sig's like to run wet", so I brought lube to the range - the rails and outside of the barrel.
I shot multiple brands (Remington, Blazer Brass, etc...) and multiple grains (mostly 115, but some 124). All brass, no reloads.
Did I get a lemon?
When it's returned from Sig, I don't know if I trust it for home defense. I recall my CCW instructor saying a gun used for defense should be thought of like a parachute, you need to be able to trust it.
