Some issues some buds and I have experienced recently with new P320Cs so I thought to bring it up to everyone's attention to see if anyone else has had similar problems with their's. All of these occurred on new pistols that were purchased in the Feb to Mar 2017 timeframe.
All three pistols just happen to be P320C-RX purchased from our local gun shop.
I discovered that my front sight was loose. Seemed okay when I purchased it new at the LGS. Took it home and disassembled it to clean it. No problem. Went to the range to break it in, setup my Romeo 1, and shot 100 rounds though it. No problem. During my second range visit, again with 100 rounds, I noticed the front sight sitting left of center. Tried to move it back but could not (?????!). Took it home and fixed it with my sight alignment tool. Third range visit, it moved again under recoil. This time I was able to move the sight, with some difficulty, by hand. Contacted SIG and shipped the P320 to them for repair. Very quick turnaround. They got it repaired and back to me in a week. They tell me they fixed the front sight and put 20 rounds down the tube....no problem noted. Just got the pistol back yesterday so I have not run to the range yet.
My neighbor had the same issue with his P320C-RX. It is at SIG awaiting repair.
Another friend's P320C-RX had to go back to SIG for two issues:
1 - His Romeo 1 was defective. It would not turn off once the battery was inserted and the intensity feature did not work with the red dot stuck at the highest intensity level.
2 - The take down lever was so tight he had to use pliers to move it into the disassembly position.
His gun went back to the factory. SIG replaced the Romeo with a new one and replaced some components in his trigger group. Turned it around in a week's time and my bud is a happy camper now!
