I did the same to minde, it cut it down in half from 10 to 5 and absolutely love it. The only thing is the trigger was and is still grainy a bit. That's the nature of the gun though, I'm spoiled with my compact Karh trigger though.
I think it boils down to what you are used to. I feel like the weight distribution on a revolver is more evenly distributed, lots of semis tend to be top heavy.
Sigs are very nice guns but you are paying a little extra for the same. I would go with a remington 1911 or even a springfield like someone else mentioned
No pink though, I think it looks maybe cheesy??? Just my opinion, if my wife is going to need it, the last thing I need the the attacker or whatever thinking that she might not be serious since it's "girly"
