I talked to Rick at Ten Ring (they bought all the USFA spare parts) and they are out of grip frames. Standard Manufacturing acquired all the USFA blueprints and some machinery. I haven’t been able to ask them if their grip frames will fit, however, Rick, at Ten Ring, said the engraving could easily be removed. A local gun refinished told me the same thing a couple of months ago.
I took these type things into consideration when I priced the pistols. Oh, and those screws got messed up by my ex-gunsmith. It didn’t really bother me, therefore, I haven’t looked for replacements, but, I’m sure they are available from Colt or Uberti.
