Probably not THAT often. This Blog has a strong and unnatural aversion to the Chinese made products. They go over the top. Maybe they have only shot the old ones, not the newer styles like the B26-28. Probably a good idea to do a tune+lok-tite on the screws just to make sure nothing comes loose before shooting.

This weakened the top of the piston to the point that after one of the cocking cycles, it auto-fired by blowing out the piston top. Now, IF that happened while I was still loading I would have lost the ends of at least 2 fingers, no amount of safely holding the cocking lever through the whole loading process would have prevented it.

Do I understand it right? You mean that holding the cocking lever would not have saved you fingers. Cocking shoe is connected to cylinder and cylinder pushes "all stuff" back. So, I think that holdin the cocking lever saves in pistonfailures too.

I ground down the top of the piston to the point where the top weld around the top of the piston was compromised. When cocked it  suddenly sheared off the top of the piston with the seal and shot forward while the rear part of the piston was still in the cocked position. So yes, fingers could be gone even if you were still holding the lever.  I got lucky. Instead it just fired the pellet without warning.

IF I were to do anything like this again, knowing how this piston was built I would have cut the the top of the piston off about 1 inch down  then removed the 1/2 inch of material that I had ground down to remove on the earlier attempt, than welded the two parts back together with my MIG. It sure looked like it was still together, but I had removed too much of the material from the factory weld the way I had initially  done this.

Just to let you know, I was able to get about 50 of so rounds off before it let loose, I was getting upper 700's (around 780-795) prior to failure.

Oh, and there are other ways this could still chop your fingers off while in a proper cocking hold. The sear could let loose, same thing would happen. Don't mess too much with that whole area on these cheap guns. Play with springs, seals, lubes and debur..
