I have a very well made lined leather bandoleer holster made for long barreled Contender/Encore pistols. Have never tried a 16 1/4" in it, but 14" barrels work fine. With a 16" some of the barrel would be hanging out the bottom. Can't remember who made it, but its similar to the MR BFR rigs made for long barreled revolvers (minus the thumb break release). Will work with open sights or scope because the scope is not inside the holster. The scope does need to be mounted high enough for the leather to slip between its objective bell and the barrel though (3/16" minimum, 1/4" is better). You might watch the classifieds for both it and an unused UM camo bandoleer for 14"/15" TC's to be listed soon.
