Do you agree with the heavy and inaccurate part?
Another complaint was excessive recoil. The slide stop to the rear added to the recoil of firing a round, causing some to complain about excessive recoil.
1. Heavy: Yes, they are heavy, but compared to the Beretta, I don't think they are excessively so.
2. Inaccurate: Yes, often they were. Some were worn from years of use, others weren't particularly tight from the factory. My Dad's service pistol is an old one, very nicely made. However, as he was in a year before Pearl Harbor and shot on the regimental target team, he said they would go to the armorer and strip a bunch of 1911s, and put together a few that were tight by select fitting the parts. Squeezing the slide in a vise also was a technique used. Dad had no use for any other handgun than a 1911. So, part of this was true, depending on the individual specimen that one was issued or "procured." I think a larger part was due to 3, below:
3. Recoil: a lot of people did not care for the recoil of the 1911. Part of this was due to being drafted into the services and perhaps shooting a pistol for the first time. Part was due to the 1911 having a rather large grip, making control difficult for some folks with small hands -- which made the recoil worse. These personal issues were, I believe, a great part of the inaccuracy complaint, above.
Still, if a lot of people couldn't shoot them well, that would be part of the problem.
Frankly, given the impact of handguns on the battlefield, I don't think I would spend much money here. Special operations teams would be a different matter, but for standard troop use, I don't see issuing a big contract for handguns to be very cost effective. If the current inventory was old and worn, and something needed to be issued, a smaller, reliable 9mm with good magazine capacity would work for most. I would hate them, because my hands don't fit a lot of what is out there nowadays. But most people could probably do fairly well with one, compared to the larger Beretta in use here. I simply don't see these things as being a big deal. I'd be looking to pour money into modern combat e-systems, nite vision capabilities, and such.
