As you all know i had the trade bug and finally scratched the itch. I traded my G19 for a G23. I like the same size but in a little bigger caliber. It is from what i can gather made in 1998. It was a safe queen and still has the gold lube in it. the barrel has no wear marks from shooting.
Ran about 60 rounds through it today. No hiccups at all. even tried some of the rounds i have mentioned in the ammo section. everything fed great. I am very pleased with this gun.
I dont see where the caliber change is necessarily an upgrade. With modern ammunition, a 9mm is good for HD, duty or whatever. I carry one at work, and its a great, rack grade sidearm, but I can feel a hair more "snap" in the recoil w/ this weapon. Personally, I find the G19 to be ideal, and very controlable. I plan on goin to a G19 as soon as I can. The ability to carry more ammo is never a bad thing, and I would rather hit w/ a 9mm, than miss w/ a .40. Good luck with your piece, and shoot the crap ot of it.
