I can only speak to what I have experience with. I have the Ruger P89 and the Taurus PT111 mil pro. Both of these weapons have never, I repeat, NEVER, malfunctioned with over 1000 rounds thru each. The Ruger is a great house/range gun but not for CCW IMO. The Taurus is a great firearm though some would find that hard to believe
The trigger is light, the slide racks very easily, and it has a double captive recoil spring that makes for a very light recoil. It also has an advantage that many other pistols in it's class don't: A manual safety. You might want to look at the Taurus Millenium or 24/7 compact. They are good
inexpensive guns.
Now, that's what I know about. If I had do-over, I would look real hard at that S&W M&P 9mm compact. I haven't shot one, but I have handled one and I liked the feel and trigger a lot. I like a manual safety, but it's not as important to me now as a feature as it once was. The S&W warranty and customer service also strongly influences me.
