the only ammo i've heard of teh KelTec being sensivie to is 147 gr. stuff. Some of it is a bit longer than 115/124 gr rounds. Any quality factory JHP whoud serve you well, including the Triton, but be sure to test fire a sufficient quantity to satisfy yourself that the gun is reliable with whatever you chose (which could be an expensive proposition with the Q/S). Maybe you should consider breaking 'er in with a variety of quality factory stuff, then move on to Q/S, or put the Q/s as the first one in the tube and back it up with some good JHP's like HydraShok or Gold Dots. Good luck with your new 'baby'.
