I'm a contrarian to our beloved Canebrake.
If I have a weapon that's new and fresh from the manufacturer, I don't trust that the barrel, chamber and internals are free of sticky metal preservative, burrs and chunks of steel or aluminum left over from the manufacturing or packaging process.
More than once, I have found these conditions which would likely have led to malfunctions on the first range trip, despite the fact that the weapon was good to go otherwise.
Not only does a detail strip, clean and lube prevent possible malfunctions out of the box, it also familiarizes me with the detailed workings and function of the various parts. This knowledge can often be the key to quickly solving a stoppage in the field.
Once I'm sure everything is assembled properly...clean and lubed and looks copacetic...it's time for test firing and sighting in at the range.
If function is good for several hundreds of rounds, then it is time to clean again and very closely inspect for wear (if any is visible) on metal to metal contact areas to make sure everything is mating together smoothly.
If everything checks out...chances are it's gonna last 100 years with proper maintenance.
I have noticed the tendency to *send it back to the manufacturer* on the forums and I often think shooters make a snap judgement too quickly. A little finesse and research can often solve problems without involving the manufacturer. I like to solve problems on my own...that's how I learn my weapon.
