Oysterboy: said:Whew, what a beast. Gonna need that pinky extension to control it.
Congrats on your B-Day! That G-29 is a handful to shoot, but it's an awesome defensive caliber once you get it on target. Glocks are reliable as the day is long I can certainly vouch for my G-17 and G-21.
As far as 10mm ammo is concerned, I hope you reload, factory 10mm ammo is scarce and pricey, although PPU factory 10mm FMJ range ammo isn't outrageously expensive and I see it at Cabela's all the time. Hornady Custom 180 grain 10mm JHP defensive ammo is good stuff but you might have to search for it or order it online in 10mm.
