Every single S&W cylinder release for K, L, and N-frame (and maybe others, those are just the ones where I know it for a fact) revolvers (both new and old style) will cut the top of my right thumb if I'm shooting cartridges with any recoil past about 38 target wadcutters. That's just because of where my grip interfaces with them. I must grind on them, or else they will cut me. (I always buy a replacement latch and grind it, so I can put the original back on in unaltered condition if I ever want to.) They're not defective... they just need that work.
A great many rear or front sights will cut you if you are racking the slide vigorously enough... such as clearing a malfunction on the clock in an action pistol game (or, presumably, during defensive use). I've seen that happen to many people, and I've had it happen to me. Again, it's not defective.
Many people will get cut by hammer-bite on various pistols, including non-beavertailed 1911's or Hi-Powers. They aren't defective.
A common gunsmithing service is "dehorning," precisely because knocking down all the sharp edges that might cut you if handled with sufficient force is somewhat labor intensive and not something done with a lot of guns that roll off production lines.
Saying that nothing on the gun, or nothing you expect to touch on the gun, should be able to cut you is... well, it may be a fine standard, but it's not reflective of the real world and what most/many manufacturers deliver.
