The Army screws things up on a daily basis. Choosing this pistol, was one of those screw ups.
Continuing to test and screw up their "enhanced performance magazine" for the M4 rifle, is one of those screw ups. (the Marines, the British army, and others, have already figured out that the Magpul mag is the most reliable. Not the Army knuckleheads who continue to waste money on their terrible EPM magazine)
From what I understand, they even cancelled the extended testing, durability testing portion of the pistol test, after Sig's ridiculous offer of over $100 million dollars cheaper than Glock.
These sealed bid processes are dumb, dumb, dumb. Whats wrong with going to Glock and saying, "Sig bid $500 million on the contract. You bid $600 million. If you can bid less than Sig, we will consider your offer. Then back and forth, back and forth, until the best price is negotiated. This of course, AFTER the guns are thoroughly tested and approved for purchase. Like back in the 80's when the Sig P226 and Beretta 92 both passed with flying colors, and Beretta won on price.
