I'm hoping to attend a few shooting matches in 2020, and I'm thinking a 10-rd mag will be fairly important. As such, I've been looking over the options for new bottom metal and was hoping to get a few opinions. I've looked at Accurate-Mag, CDI and PTG.....bascially those items dominate my internet searches......any other options I should consider? It seems the main difference in the options I've listed are 1-piece vs. 2-piece design.....any advantage to leaning one way or the other?

Thanks!
