I feel your pain. I have talked about this a lot, if you do a search I'm sure you will find it.
Right now is tough because everyone is buying mags. What I did is buy 2 12 round mags for the 24/7 Pro .45 which fit fine in the compact (just a gap because your missing the sleeve). The other thing I did and also someone else has tried was I bought the 10round compact mags for the PT145. It has worked perfect in my gun so far and fits just as flush as the 24/7 compact mag.
It does suck that Taurus lags so much on their customer service but they sure do make excellent weapons. Congrats on your purchase hoped that helped a little.
