I already had a TK Custom loading device for my S&W 686 chambered in 9mm. I just had my S&W 627 rechambered for 9mm. I did not have to buy another loading device, as suggested by TK, I only needed a different mandrel. I used it for the first time last night and it worked perfectly. It just needs an allen wrench to remove one mandrel and then attach the other. Very easy, took no time at all. I appreciate the suggestion from TK. It save me some money!
