for the .327 Federal Magnum, and were available in 2.2" or 4" stainless steel models. The Charter Arms web site as of August 2011 no longer lists this model under the products category. Also in 2008, Charter Arms announced a new revolver: the Charter Arms Rimless Revolver. The new revolver would be able to load and fire rimless cartridges such as the 9mm, .40 S&W, and .45 ACP without the need for moon clips. Initially, the revolver was to ship in early spring, however, reported problems with the patents delayed the introduction. Charter Arms set a release date of April 2009 for the CARR. However, Charter Arms missed this deadline, and company representatives have suggested the release date may not be until "late July" of 2009. The CARR which was subsequently called the Pitbull finally reached production in August 2011 and the first Pitbull models had a 2.3" barrel and were chambered for the .40 S&W cartridge as this is the most popular U.S. law enforcement round and would enable the Pitbull to be used as a back-up gun to the .40 service pistol.
