Normally, I wouldnt reccomend anything from Rap4 to be honest, but their soft goods are actually well made. That said, you have to ask yourself one question;
Do you want to draw from the hip, or on a vest some where? You have to play pistol at least a few games before you can find out what's most comfortable.
From the hip, I suggest this
Other options, depending on your vest
Good luck. I would definitely play pure pistol before you invest in anything though.
