I sent a S&W Model 686-1 and had the cylinder cut for moon clips. I then sent TK Custom the cylinder for my S&W Model 629-4 and also had it cut for moon clips and next week I will be sending the cylinder for my S&W Model 642-2 to get it cut for moon clips. TK Custom does great work and the turnaround is about two weeks.
Taurus supplied 5 "stellar" clips with my new 692 revolver. Upon loading them with cartridges, 4 of 5 broke tines! I ordered TK moon clips and have had no problems at all. TK makes them "the way they should be made." Tough and durable.
