I do think there is a bit of an issue if a gun looks too toy-like....maybe a bit more likely to have to pull the trigger, as it may not be as 'scary' to the bad guy visually. Worse still - it could be found by a non-gun-trained kid, and they would be more likely to assume it wasn't a real gun (and that is perhaps more likely to happen with a firearm a belonging to a woman, to the extent they are probably the kid caretaker more often, and also to the extent many women carry firearms not in a holster, but in their purse instead...).
I'm NOT a fan of purse-carry.
Nor a fan of moms who let their kids dig around in Mom's purse (....usually grabbing the cell-phone to play with....

). If any of our kids had ever just started digging around in my wife's purse, the next time they would have (literally) encountered a mouse-trap. Off Limits.
However - I really DO like the ergonomics (at least visually).....Glocks are not just too-square on the slide, but the GRIPS are also very uncomfortable to my hands; I never liked 1911 grips, until I got my 'double-wide' P-14, which has only 3/16" more girth, but the smooth rounded profile is awesome.
