We have a small group around here and we have been getting together lately for a little competative shooting...later we plan on trying an IDPA match or two...I have always shot either a 40SW or .357sig....I currently shoot and carry a Walther P99 in 40SW but have been think of getting another one in 9mm for practice and competition...mainly because the ammo is cheaper and the recoil is slightly less allowing quicker follow up shots in competition....do you guys think this is a good idea? or would I be better off just staying with the 40SW... Can you buy light loads in 40SW this might help with follow up shot in comp...I already realize that I can buy a lot of ammo with what I would pay another P99...Thanks
