This gun perked my interest and I have thought about putting it on my list of guns to own. I have seen it online fairly cheap on multiple websites especially if it is used. My question is, why is this type of Sig pistol so cheap as compared to many of the others? Sig is a very good brand and the prices seem very good on the pro 2022 from what I've researched. Has anyone had experience with this gun before who can vouch for or against it?
