That's why I used the word perceived. I don't think they need a ramped barrel unless you want to go well above book max, and the current delta comes with Novaks, a beavertail, extended thumb safety, dual recoil spring setup, and even comes in a rail version if that tickles your fancy. They look pretty good to me.
There's no denying that a stock Delta simply will not handle hot loads as well as other better set up 10mm, whether 1911, Glock, or Witness. It's more than just "perceived", if you've shot many full power 10mm loads through them.
