I prefer to take one or two with me.
If transiting or visiting states with magazine capacity restrictions, I can go with lower capacity autos, or revolvers.
I don't have any 10rd mags for hi-cap pistols, as I find the size of the hi-cap pistols unnecessary if I can't use hi-cap magazines.
The only full-size, low-cap auto I would take would be a 1911.
My other 10 or less capacity autos include P7 and PPS, so if I am limited to 10, I might as well go 8+1 and have something that is easy enough to shoot, and very easy to conceal.
