Hello, i have an extra cylinder for my 686p-6 and i want to get it cut for 9x23 primarily to have the versatility of shooting 9mm. Im looking for reviews on Pinnacle and TK Customs conversions and if one is better than the other or if they both do a fantastic machining job. Are the TK Custom moon clips a good option or are there better out there at a cheaper price? Is 9mm crimp jump existant on L frames or only an issue with alloy J frames? Also, how bad do 357 mag cases stick in the cylinder after the conversion? Nay sayers please hold back the "why not just shoot 38s", "you can upload/ download a 38/357 mag to match 9mm ballistics and recoil", " You wont be able to hit the broad side of a barn standing 2 feet away from it if you shoot a .355 diameter bullet out of a .357 diameter barrel". I want the versatility of 9mm and i have a spare 6 round cylinder (for those who dont know that you can make a 7 shot a 6 shot and vice versa) i have already fitted to my 686p that will be the test dog. Thanks in advanced for all the guidance and input.
