I've had a SigPro 2340 in .40 S&W for years, and I bought a 357SIG barrel for it early on. It's been a great shooter and I've never had ANY problems with it shooting either round. I don't think there's too many changes between the 2022 and the 2340, as they're both available in 9MM, .40 and 357SIG. The 2022 is simply the newer version that replaced the 2340. The thing shoots great, but it's somewhat large for any type of concealed carry use.
