What is the most reliable out of the box 9mm carbine / SBR / Braced pistol?

[Ron3]

For under $1000 not including optic.

How about an imaginative scenario?

-Like a video game, you start with your choice of 9mm pistol.

-You only have 124 gr 9mm JHP ammo and 10 top quality mags for the weapon.

-You are to pick one of the offered 9mm carbines / SBR's and mount your choice of optic on it.

-You are given 2 hours and 250 rds to practice and zero on a 50 yd range.

-Then you'll be "bugging out" out of the city (which is in chaos...or something) by car, with "others" to a small town the next day. (No time to order parts)

-If the roads are blocked or your vehicle disabled you'll have to hike the rest of the way with your "group". You may have to hold up somewhere and repel bad guys or whatever.

-The journey is 10 miles. It's hot.

What 9mm carbine / SBR do you choose?

I'd want the most reliable one. I'm not exactly sure which one that would be.

Of these, I've had the Cx4. It was perfectly reliable. I've fired the Sub2000 and didn't have problems. But plenty of others have. The Ar9's I've fired didn't run perfectly, and many varieties of them aren't 100% reliable. I'd like a 9mm carbine but not sure which to get so I'm getting input.
