I purchased one of the early SIG 365's (April 2018) and the trigger bar spring fell off after only 65 rounds. (known early production issue, outsourced part) However, SIG went the extra mile, replaced the entire slide and striker assembly, and turned it around in just a couple weeks. Since getting it back I've shot almost 3,000 rounds of all types of ammo without a single failure of any kind. It's an amazing little pistol.
Have faith, SIG will make it right!
