My first 44-40 cal. Its a 4-7/8" . Barrel is stamped Colt Frontier Sixshooter. I bought 3 boxs of ultramax cowboy loads to shoot and ordered dies. I am excited to head to range! I plan to use it for a self defence pistol in a tom threeperson belt holster. I called Colt today they said it was made in 1993 and no longer made. Was made for a few years only in the 3rd. Generation series other than the early prewar frontier sixshooters.
