Hey Keiller--i''ve got a Caspian Frame on my single stack racegun that i used for IPSC and now use for NRA Action pistol...Works for me--A few years back i sat down with a caspian catalog and a Denny's catalog and was going to get all the best goodies together and build me a limited 45...But after compiling all the parts prices and figuring i would have to pay a great Smithy probably 500 or so dollars to put it all together---i just bought a Les Baer and i swear i think i saved money. Regarding Kimbers--They are good guns and i think they are a lot of gun for the money--but they are not a custom gun--a buddy got one of the match versions the other day and i could take the barrel bushing out without a bushing wrench--maybe i'm wrong but that dissappointed me....Dick
