Mil Pros aren't single stack though. But you're right that they are great pistols. I have a PT140 as my CCW, and it's amazing.
And Joel, you're probably right. As time goes on, technology does get better and more reliable. People argue all the time about which firearm is "the best". But there really isn't one. You're correct to guess that most modern designed and built guns are extremely reliable. Some will say Glocks are th most most reliable. Others will say SIGs, and other Rugers. They're all right. Modern guns are designed on computer, and this allows the designers to "test" them a million different ways, before ever even making a prototype. Some old timers will say that computer designed guns are junk and there's nothing like building a prototype in a workshop and refining it by hand. Well, when they designed the F-22 Raptor, or a modern Aegis Cruiser, they did it by computer. And these systems work very well. Computer simulated testing works. Plain and simple. So a modern computer designed Glock, P99, or USP are all going to have about the same level of reliability. And that level is very high. Some will tell you gun design peaked in 1911. Let them believe what they want, it's their choice. But don't be swayed by them too much. Gun technology is advancing every day and every year, and you're pretty much right to think that the modern guns are going to have the edge. Of course every new design will have a few kinks. But after a year or two, they get worked out, and we're left with amazing guns. In this day and age, of computer testing and design, we will probably never have another crap design like the very first M-16 or the Shosho. Those designs are weeded by computer out before ever coming into reality.
