One of my kids bought me 2 8 round ProMag 1911 magazines for my PT-1911. They have run flawless now for 6 years. I use them more than I do my factory mags. That said, I won't spend my money on ProMags but I guess there are some good ones out there.I'll never buy anything with Promag on it again. They make the worst junk ever. My simple 10 found procrap 1911 mag split the feed lips on the first loaded magazine.
Promag uses terribly cheap metal.
