I realize I may get some biased answers herebut I was wondering your opinions on trading a Springfield XD Sub .40S&W for a P99c .40S&W? Has anyone shot both that can comment? I am leaning towards the AS trigger so I can carry one in the chamber decocked, and leaning towards .40S&W as I already have an H&K USP Compact and about 1,000 rounds of .40S&W range ammo in my safe. Is there much difference in recoil between the 9mm and .40S&W on the P99c? Would it be worth it to add another caliber to my ammo stash by going with 9mm? If the recoil is about the same, it may not be worth it, but if there is a significant difference in a compact frame, then maybe I'll switch. Comments are welcome!
