Q.C. vs normal upkeep vs modding vs tuning to perfection

Recently there's been some discussion of maybe insufficient attention to QC on the part of manufacturers. With an occasional exception, I haven't needed any major work on my stable of babies. (The Aspen being a notable exception, and kudos to Pyramid Air for their fantastic customer service.) My LCS, Crown, P-Rod, HW44, HW75, 1701P, Leshiy2, PP750, 1322 and my Bulldog (and quite a stable of CO2 pistols) have each done precisely what I asked of them, every time. Which is to shoot when I ask them to and let me be accurate on paper, feral cans, and the rare obnoxious squirrel. Yes, some triggers are sweeter than others, but I am okay meeting my guns where they live as long as I can shoot accurately. Now, I haven't shot slugs (yet) and don't have springers (yet). My backyard range is 10m - 50y. At peak season, probably shoot 2 - 4 tins of pellets/week, rotating through my babies. Sure, I've done some optional mods on the Crosmans/Benjis, because they're fun & easy, but not because they weren't working. Am I missing something? Are my standards too low?
 
i'd say getting a gun that leaks or as in one recent case i got a gun with a smooth barrel that the factory 'missed' machining rifling into, is at the very least not as rare as it used to be ... the problem is the modern environment of entitlement , people have been conditioned into the marxist idea that they deserve everything easy and integrity productivity and quality take a back seat .. thats why socialism is so destructive to a society .. theres no drive to excel ...
