With any garbage ammo you fine lying around in weeds to feed through it. The darn gun is essentially fool proof … which is why police forces love them (Glocks, not specifically the 26.)
That said, I do question the Army’s wisdom to replace all the M9A1 Berettas (which are fine as basic side arms) with a whole bunch of Sigs. The sig is the better pistol but they spent a stupid amount of money on something an infantryman doesn’t use all that much. The Beretta was fine for its job, a last ditch way to defend yourself.
Then again Big Army isn’t all that smart anyway since they are adopting the 6.8mm to combat Chinese and Russian body armor. Which as has been shown in the media isn’t really an issue because the Chinese don’t issue body armor outside of their Marines and Russian body armor might as well be Vietnam era flak vests.
And frankly that’s what the new M7 should have been chambered in. .308 with a tungsten core will punch straight through even level 4 plates without too much trouble.
But as per the contract the round could not use tungsten. So Sig built this really crazy 6.8mm round with a bi metal case and the pressure out of an 11 inch barrel is 90,000 PSI. That thing is going to be a barrel muncher.
But then again who the ■■■■ is running level 4 plates as standard issue anyway?
