Are semi-auto revolvers legal for DR?

Well, it looks little bit like cheating to me  No, I'm not planning to shoot Mateba or Webley Automatic any time soon, but just out of curiosity, are there any existing rules that explicitly ban semi-auto-revolvers for use in DR competition?

Not sure about Meteba, Webley might be eliminated owning to the size of the caliber.

There is a rule that says it must be SA and DA capable. Eliminating all SA only wheel guns. I'm thinking it eliminate any revolver that couldn't do both

Well, Mateba is SA/DA and it's chambered in 357 Magnum, so...

And just a spring swap for it to use 38 special ....
