If you like the P7 and shoot well with it, the disapproval of your partner is a poor reason to change. Sounds like your partner is stuck in the mindset that thinks .45 is a death ray and the 9mm is good for nothing but plinking. Stoke that P7 with Winchester 127-grain +P+ or a 124-grain +P Gold Dot, and it will equal or outperform just about any .45 load out of the 245's short barrel, with less recoil and probably more accuracy. I've tried just about everything out there for off-duty carry, and what I found works best for me is a Sig P228 with Winchester 127-grain Ranger T ammo. It's accurate, totally reliable, and very easy to shoot one-handed (think about potential off-duty scenarios, like having to pick up one of your kids while engaging a threat). Personally I love the P7, and would probably buy one if the manual of arms wasn't so different from everything else I use. Nice and flat, reliable and accurate as heck. I'd stick with it.
