I'm gonna start shooting single stack soon and need some advice. I will be using a range officer in 45 acp and have installed a Dawson .90 fofs, vz operator grips, Dawson gap mag well and grip tape to the front strap. What I need to know is what are the best mags and mag pouches. Also, do I need an ambi safety? I would think so when shooting weak hand only in matches, but hey I'm new to shooting competitions and what do I know? Thanks in advance for any info.
