My dad had 5 guns go down in a week LOL.
Kart slide lost extractor, Goldcup sheared front sight, Python cylinder had issue, Contender had spring break...........think the other a HS with custom bbl for IHMSA.
Shoot a lot, components wear/break.
He fixed 'em all and kept on blasting.
They all had a ton of shooting through them before the problems popped up.
Quickly fixed, back in action..............the only one to repeat a problem was the GC, which did not have a dovetailed front sight.
Most times a gun has a "problem" it's not the gun. Crap ammo, wrong ammo, neglect, abuse, misassembly, changed components.
Debugging why something doesn't work..........seen too many think they know the problem and want to break out the files/Dremel. Even supposedly professional folks who should know WTH is going on, can bring you something with a problem, give detailed info..........and be totally wrong.
So you smile, listen, and give them a time to call back. Then with them gone you start at ground zero and do the debug.
Have seen some horrible engineers and tool and die masters who were clueless as to what the problem was. Too often folks want to just grind and go.
Scary.
No doubt they post their findings on the web and smear a company that may not be of fault, or if there is a problem, misrepresent/misinform.
My findings on Taurus are first hand, across a decent time span, of some detail.
So bad, for so long..........now I won't touch any of their products, even if wearing nitrile gloves
