well I have thought about it and only want one cal. I have tons of 9mm as well as most of my other guns are 9mm so... but I really miss my 1911 and thought I would get one in 9mm
Then yeah, the STI is prob gonna be the most reasonable priced and reliable. You could build one yourself, but heard the 9's are picky, so dont know how reliable it would be. A coustom shop would do it, but then you are going to be spending some $$$
