Peacetime military, (yes, there was a time), we had 1911A1s on the ship. The OTHER services had gone to the Beretta in the late 1980s, but the Navy was holding out. Heck, some of the antiques in my armory were marked Remington-Rand! They ALL rattled like castanets, but they all worked. Even the one an idiot dropped in 118 feet of salt water, complete with belt, holster, spare mags and pouch, that I got the fun of watching him clean after the EOD diver we had on board brought it back up.
To put things in perspective, my Dept switched to Glocks, (17s and 19s), about 14-15 years ago. We no longer train with the G-19s on the range because the G-19s we used for practice are far too worn out for anything but recycling. Now we are working on the G17s we use for other duties. The ship board 1911s had been there since the late 50s, from the records I remember seeing, with a few being replaced here and there, and shot every quarter. Oddly enough, we had 4 Ruger Service Six 38 revolvers, too. No ammo, no holsters, no speedloaders, nothing, but 4 wheelguns, never did get an answer from anyone on why.
Does that mean the 1911s were superior to the Glock because they lasted so much longer?Boy will THAT question open a can of worms...!!! No, it doesn't, because the range Glocks got a minimum of 300 rounds through them every week, and the 1911s got about 1000 rounds through them every 3 months or so. How do I know? I got to load the magazines...low man on the totem pole.
What should we go with? That is a question that is very easy to answer - whatever that will go bang when we want it to, won't go bang when we don't want it to, hits the intended target and lays a hurtin' on it. That;s simple - the REAL work is Congress - a system of appropriation and replacement that ensures pistols nearing a planned life span end should be rotated out of service and surplussed, to either friendly Third World powers or CDNN Investments, with new pistols of the same make/model brought in to replace them. I realize it ain't a perfect world, but in said perfect world armorers would be able to surplus pistols that nearing replacement and provide new ones, with the worn ones serving as third line or training equipment before being surplussed completely.
Then again, I'm just an old squid with one total day of combat in my whole wasted life, so my opinion is worth what you paid for it.
