It looks like I will be going back, and I wish to Zeus I could just take my Kimber and not have anyone look twice, but I know this isn't realistic.
As an armorer in Germany, we switched out our 1911s for Berettas in 1992, and I had ALL kinds of problems with them. Soldiers taking off the handgrips and messing with the slide bars and springs, lousy mags, failure to fires, etc. I remembered thinking at the time, "No way in hell these things are going to last as long as the 1911s did."
The BEST is probably the H&K .45. BUT, the vast majority of the soldiers carrying this pistol will never use it. I think you will continue to see elite forces get small contracts for H&Ks, and high-end 1911s, but not for the general contract. They won't pick a SA auto for the general contract, because let's face it, the AVERAGE soldier needs the least complicated weapon thay can get. Having a pistol with a hammer AND a safety is going to mess too many E-3s up.
As long as we are with NATO and pretending to follow the Hague Accords, we will be using 115 gr, 9mm, FMJ. Which means we should issue the BEST 9mm, that is the least complicated, most reliable, and universally accepted. The G-17. (I voted for the G-22 because the 17 wasn't listed.) The XD may well be as good of a choice, but I would like more time to see it.
