Anyone know where that guy is located? Sounds like somewhere in Britain. I noticed he cut away a big chunk of the serial number when opening his loading port.
Given where that hammer strut failed, I suspect that there may be production variation in the bend that could be inspected and failure predicted to be more or less likely between several parts. Possibly some tuneup of the surface tooling marks to reduce the likelihood of failure, but the struts are cheap enough that part selection might be a worthwhile strategy.
I saw the mag tube wear issue discussed on the net years ago; it may have been that video. On my Gen 1 gun, the inside of the gas piston felt quite rough, and you'd expect it to wear the tube. I smoothed it until the edges no longer felt rough or sharp, hoping to reduce the wear. I can't say I've put enough rounds through it to judge whether it was successful, but I feel better having done it. Variation in machining on the ID of the piston as tools wear would be an expected reason for variation in the rate of mag tube wear between guns. One gun showing it in a few thousand rounds and another going past ten thousand without a problem doesn't mean one owner is doing something wrong or reporting fakenews. I speculate that management of mag tube wear may be a reason for the coating on the Gen 2 piston. Any Gen 1 piston should be able to be cleaned up to be as non-aggressive to the tube as another.
Midwest Gun Works has 1301 parts at reasonable prices. Hammer struts are cheap, mag tubes aren't bad. This is a new development in the past few years, which I suspect @e_stern may have had a role in.
