Well, its not a 10mm, but I finally had the chance to shoot my new G19 Gen 4 this morning, and I have to say that is one sweet gun! The most popular Glock out there, and I can see why. Not too big to CC, and not too small to have accuracy and it feels great in my hand. Ammo is a bit less expensive also. And anyone says a 9mm doesn't have knockdown power, is very wrong. I would recommend the G19 without hesitation. But thats just me.
