Thanks, all.
According to a local there are three local groups that host WB and they all have open class where I might be able to use my XDS 45.
Meanwhile, my boyfriend seems to have his heart set on a Sig 1911 Match Elite in .40 cal, while 45 ACP is required for WB and a double stack 9mm is best for 3gun. I'm not sure where he would compete with what he wants to buy.
I don't really have a budget, per se. I'm a patent attorney so I have plenty of income at the moment. The message I seem to be getting is that I need 2 different 1911s for WB and 3gun, and plenty of time to figure it out. I held and sighted every brand of 1911 I could find at the gun show, and I liked the Ruger the best. So maybe I will eventually get one of those. I'm not sure about the double stack 9mm though. Who makes those besides Glock? I always feel like I'm holding a brick when I try one of those.
