I usually stick with Wilson Combat or Chip McCormick.
Tripp Research Cobra Mags. Cost the same or less then a Wilson Combat 47D or 500ETM. These magazines are used by most USPSA shooters who shoot single stack division. I put rough 12,000 rounds through the 8 Tripp Research 45acp mags I use in USPSA competition and 3,000 rounds through the 8 Tripp Research 9mm mags I use for USPSA competition. Best place to buy them is online from Harrison Custom.

I think the flush fit are 7-rounders, mags with the bump are 8-rounders. Whatever you feel comfortable with.
So I'm not seeing "Powermag" anywhere in the description. Is it still any good? Does CMC make different quality level mags?I stand corrected
I personally would trust anything that chip McCormick puts out. YMMV
