I like some of my others just as well!
But for reasons of simplicity of carrying only one caliber of ammunition with me I would take my Glock 22 and my Glock Model 27 both in 40 cal. That way I could pack as many rounds as I could carry (40 Cal.) and they would work in both weapons. Including the 22 Mags would work in the 27 to increase capacity. They would have more capacity than my beloved 1911 45s. Other than that my choice would have been my 1911s.
