The G-men: G2, G3, and Millennium Pistols
I now have my PT24/7 Pro 45 to 10mm completed, and was looking at my PT145. It seems like something similar could take place here seeing as how they use the same mags, albeit 10 rounds vs 12. I found a complete PT140 Pro slide, barrel, and RSA for $95 shipped, so I figured I'd give it a go...
