The new P322 was completely designed and built by SIG SAUER in New Hampshire and is loaded with premium features, including an optic-ready removable rear sight plate so you can easily add a ROMEOZero red dot optic without the use of adapter plates. The P322 also comes with a threaded barrel adapter making it suppressor ready right out of the box, and with its ambidextrous controls, interchangeable flat and curved triggers, and fiber optic front and rear sights the new P322 is the highest capacity, most advanced 22 pistol in its class.
I have nearly 1K rounds, and I can say I have not had any issues. I am thinking this might be hit or miss, as I have heard of others having leading issues. I have not seen any leading issues or any issues with the magazines. The magazines do require you to take your time to load them, but it's nothing special. I have been primarily using Fed Auto-Match and found that it runs well. I might have had 10 rounds out of 350 that had issues, and most of the issues I found were related to how I loaded the magazines. Sig did alright by me.
