My condolences on the pistols Steelfan. I say go for the P210 ,it is a true classic and possibly the best auto pistol ever(yes including the 1911 ,sorry yanks). As far as issue pistols it could be worse the US has some nice Berretas with garbage mags that fail to feed even if you only have 10 rounds in them.
I think the US should go to .45 for morale and because they are not allowed to use anything but nonexpanding ammo. With good ammo a 9mm is just as good but if you are stuck with underpowered FMJ(US 9mm is weak)then at least get a big one.
Also I think it would make them happy and more confident just because Americans love the .45 so why not.

Canada's armed forces still use the smae old HP's some of which are very old but if you have small hands you can get a nice little Sig.

Heck I am not even a big fan of handguns. I much prefer a rifle and a good fighting knife. At the kind of ranges most civilian gun fights occur at a knife is as good or better. One place a handgun is ideal though is in a car.
