See post 13. Some on that forum apply the 2000 round rule before deeming a gun worthy of staking one's life on and willing to carry it.Quick question.... which do you feel is more reliable..... a gun with 2,000 rounds through it with no failures? or one with 200? Finally, is an owner likely to be more proficient with a gun after 2,000 rounds? or after 200?
I don't know what the 2,000 rd rule really consists of but I'm sure they want to you shoot at least some of your chose carry ammo through it. Personally, I kind of torture test mine. I put all sorts of ammo including several types of SD ammo through it, just to see what it will do. YMMV.
I think that a few guns are somewhat GTG out of the box after a function check. G17 & G19, and M&Ps of most varieties. It you clean it, lube it, and it functions with cheap crap steel case ammo and some quality +P+ they are in all likelihood going to be good to go. Double check your carry load for function and accuracy and run with them. Other than those models I want some rounds through them like you and a box or two don't tell me much.
