I just got the wife a 365 Fuse to replace and absolute POS Glock 48 that after +-300rounds would finally, sometimes, get through more than 1 mag without a failure to function using various type of ammo. She is very happy with the upgrade....and the 365 platform is an upgrade in every sense of the similarly sized Glocks. Great features, high capacity, good trigger, direct mount optics, modularity.
A couple of things to take into consideration about the Sig 320 "issue". First, the reported issues have only been with the specific 320 9/40 platform...NOT the 320 X Ten or 365s which are completely different platforms. Second, take everything you "see" with a grain of salt.....and I use that last word intentionally. There are a LOT of folks with very specific motivation to try and find anything possible to attack Sig because of the last cycle of military contracts. Salty would be an understatement when describing that subset, especially the Glock fan boys. Any piece of machinery or media can be manipulated in order to "show" what one might want. I have been selling guns for 5 years now, our shop has sold THOUSANDS of 320 variants and has not had a SINGLE complaint for anything relating to this issue, stores across the world continue to sell them (and I assure you that insurance companies are VERY apt to cut us off from products they see liability in and could not care less about military procurement), and military and police continue to use the platform. Personally, between my 320 AXG and the various 320 variants I have shot in training I probably have 5-7000 rounds through them with ZERO issues.
All that being said, food for thought, if you have to pick a single semi-auto pistol for absolute dependability I would say you have two choices and they are a "U pick'em" situation.....HK USP or Sig 226.
