Watch plastic defense [0]. 3d printed guns have come a long way.
For international crowd, something like FGC-9 is closest to reliable printed firearm they can get. It is hybrid. The barrel is created by 3d-printing jigs for electro-chemical machining a standard high-pressure pipe, yielding glock-like accuracy and durability of barrel. Bolt requires some work by hand. Rest is unregulated components and 3d printed.
In the US, the receiver ['firearm'] is the only component that looks regulated to the consumer. The UBAR for instance is a printed AR receiver reinforced with off-the-shelf U-bar that is extremely durable, and unless you're mag dumping or leave it in a hot car in the south or something should last thousands of round. The non-receiver parts can be bought without regulation in US.
Also bear in mind here, in self defense less than 15 rounds are typically fired.
>feel like really cheap, soft plastic.
FDM materials like PLA+ can be resilient when kept out of heat. Nylon-X and carbon fiber reinforced materials, depending on application, can provide even more rigidity and strength. Most of the stuff you've seen printed has probably been with cheap PLA with low in-fill (faster print time, somewhat hollow inside the shape). 3d printed guns are printed with very high 99+% infill (mostly solid inside the shape) with at least PLA+ to provide much more strength.
