Most firearms are relatively simple compared to other devices we use every day. Identify the issue and either fix it or have it fixed. Test to your satisfaction and enjoy it. Exception would be an obvious design flaw most of which will not stay on the market long term. The other issue I see is lack of operator knowledge which is them considered a design flaw I.E. lack of a disconnector on Win 12, 97 and Ithaca 37 shotguns. In pre internet days many WWI and WWII vets considered that as a feature rather than a flaw.
