No experience with the "Pro" LC9-S but I own a regular lc9-s with the safety and mag disconnect. The safety and may disconnect is the reason I chose the lc9-s. I like those features in a gun. Also own an SR9 and that is my house gun.
I've owned so many guns I honestly have lost count. Several glocks, including the 26. Owned a Shield too. I know a few have complained about the lc9-s on here, but mine passes all tests required. Factory ammo, hollow point, reloads, ALL fire and eject fine.
As for the new Glock, the 42 had issues. I would wait to get the 43 until they are worked out. Cause one thing I know is Ruger will make ANY issues that MAY come up right. Glock doesn't have that rep. Call them with a problem and they blame the ammo, the shooter, the Earth's gravitational pull, global warming, or whatever else they can come up with. And they sure aren't going to let you exchange a gun at no cost to you.
