How Spicy is the 5.7? GT Science By: Keith Finch

The 5.7x28mm has had a successful resurgence in popularity. New ammunition and available, new pistols, and new carbines have all combined to give the round that is essentially 5.56Lite a new lease on life.

But is it effective?

That seems to be the cyclical question, are the available ammunitions good as a sidearm round or PDW round. Does it do defensively what is required of a sidearm or PDW? Does it, at the least, compete favorably with .380 ACP, .38 SPL, or 9mm?

Mike and the Garand Thumb team are looking to put a little science behind the inquiries and generate data to form answers. I’ll say for certain that the Belgian armed forces use it as their sidearm, and they are not slouches in selection. But in contrast, I also know how military procurement and firearm selection can go and you sometimes just deal with what you have. M14, M17/M18, M9 with the bad mags, just because it is in use doesn’t assure its greatness.

Anywho, enjoy the vid!
