SIGs are quality handguns. I have had a P226 since 1982 and have never had any issues. That said, I recently purchased a SP2022 and do not expect it to have any issues. It seems to be well built. The reviews I read during my research on this model never mentioned durability as an issue. One common theme was that this handgun was a great value.
Below is a link to a pretty thorough review:
