I have maybe 10 recent vintage revolvers, (after the lock era) mostly they are alloy frame models. Not a single real problem with any. But, from some of the problems g=seen on the forum, I wish they would step up their QC dept. A 5 minute inspection of every gun by a $35 an hour guy would cost about a $5 copy. 12 revolvers per hour +$60 to cover wages and bennies. The cost per gun of those rejected upon receipt by gun store or buyer has to be way over that. Return and reship cost of just 1 gun would cover at least 10 guns. I did not factor repair cost as with good QC dept that would happen before original distribution. Then there is the all important value of product reputation.
Actually wouldn't take 5 minutes.
Look the gun over, dry fire it on all chambers while aiming at a dot on wall to check appearance of sights, swing out cylinder, look down barrel with light in frame, then look in each chamber. Look at forcing cone. Close up, try a .003 feeler gauge for a GO and a .009 for a NO GO. If rejected attach a tag with check mark in the failed spot and sent to rework.
Guns like the ops with cosmetic fails could be either sold at a discount with or repaired. If sold at a discount, a mark could be placed on them to designate that. But, the factory could change out that barrel pretty fast.
