$350 is a great deal for a reliable striker fired pistol anytime (pre or post pandemic), but my hesitation with the APX would be in the availability of stuff ... extra mags, holsters, etc.
But if one can get the doodads that one needs for it, that's an awesome price.

Magazines are fairly easy to come by being that it's not a super popular pistol.
17 rounders are about $23 and 21 round mags are closer to $30. Similar to Glock prices.
