Both of my trigger groups have "dings" alone the housing spline. What causes this?

A lot of them have it, including mine and bad andy's, mine is TRW and I believe his was HR. I think it is from armorers peening them to get a tighter fit, long ago. If you look closely at mine and andy's, you can see each individual punch mark, to spread them out. Again, I am not certain, but it is the only thing that makes any sense in this mind of mine.

some splines look as if someone or something got angry not just mere pinging or what have you.

My guess is 18 year olds trying to jam them into place. If you don't align it right and try to force it in, I think you can mess up the spline.

Its not the jamming the T/G into the stock/receiver its the ripping on the T/G to remove it from the rifle that chews up the spline, sometimes getting the T/G too unlatch feels like mission imposible on its own.

What I don't understand is how the majority of M1 Garand trigger housings I have seen have nowhere near the wear I see on M14 trigger housings. They are practically identical.

Example:

The only reason I can think of is the M1 has a long floor plate this keeps the T/G from fliping out and winging the spine, the M1a/M14 has two small feet.

Phil is exactly right on his answers to both questions. You just can't move the trigger housing as much on a Garand because of that longer bedding surface when you take the trigger mech out.

One thing as well, the slots on some commercial semi auto M14 receivers are so tight some folks wind up beating the trigger mechs in with a mallet. When that happens, it is just best to file the key a bit thinner so it goes in correctly.
