OK, this thread is starting to drift now from it's original theme. Further discussion of your PT24/7 Pro should probably go back to your original post on your Problems with it.
I still think you may be having a Magazine problem with your 24/7 Pro Pistol, but my experience with this particular Taurus Model is limited at this time. Taurus did have magazine problems (weak springs) with some of the early .45 PT24/7's. Yours could be one of them. If not a Magazine Problem, have a look at the extractor area. It may need to be cleaned.
Another thing you might do is seek the advice of a local gunsmith, familiar with the design. Don't know the shop you bought it from. The problem with some Gunshops is that all they want to do is $ell you yet another gun, rather than fix your problem.
My experience with other Double Stack .45 Magazined Pistols (Para Ordnance P14, EAA Witness) has shown me that they can be a bit tempermental at times and are very dependant on having good Magazine Springs in them. However, their problems are usually not insurmountable. The EAA .45 is still one of my all time Favorite .45's and I've trusted my life to one, on occasion. The 24/7 Pro .45 is still on my shopping list.
