Smith & Wesson M&P 5.7 - Tempo Barrel System

It’s basically a gas piston system. With the barrel acting as the piston, and the bolt. Very clever.

It’s still on the fence with this cartridge. That’ll likely change when I get a chance to fire one. I try to stick with cartridges that I can reload, and as of now, I’m not set up to load the 5.7 x 28. Nonetheless, I am loving the innovative solution by Smith & Wesson in their pistol. Very interesting design.

I agree. 5.7 isn’t in my list of calibers I reload or buy in bulk. And it doesn’t fill any need of mine so it likely won’t be in the future either. But the pistol is still really cool regardless.
