I am considering the Cimarron model P because you can get it in 44 specl. A choice is given for frame type.One is listed as Old Model Case Hardened and the other choice is Pre War Case Hardened.Can you discribe each for me?I emailed Cimarron but am not getting any reply back which, by the way,may chage my mind as to the company that I buy from.I will consider other 1873 Colt replicas under good advice as well. Thank you.
