They're similar, TAP and ZMax have a cannelure, while VMax does not, though I believe construction is similar. Don't forget to put a few solid copper ones at the bottom of the HD mags, just in case.
Already ahead of you. I got a 42 round promag I have 22 fmjs at the bottom and 20 TAPs at the top. Hopefully I will never need it but the way it is getting these days I even have my 1911 follow me around the house or within arms reach.
