I have a 629 Mountain Gun I'm currently using for IDPA ESR. I had the original SS cylinder cut for moon clips; the TK Custom clips work great. I did have the cylinder stop peening problem that was mentioned above; I suspect that it was caused by exactly the situation described (lots of dry firing and slamming the cylinder shut on reload practice). I've since replaced the SS cylinder with the titanium 329PD cylinder. I'm currently using 240 gr FP copper plated bullets from Xtreme Bullets. On a moon clip I haven't had any problems with them hanging up on the reload. The copper jacketed bullets seem to slide into the cylinder better than the factory lead flat points that I had previously used. HKS does make a speedloader for the 629. With the titanium cylinder the 629 Mountain Gun I wonder if it might make it under the 42 oz. requirement. I'll have to weight it at the next match. SSP would be interesting; given the weight of the bullets (240 gr or 200 gr) I suspect recoil would be pretty tame.
