The G22 is already being built in America, so that pistol would be a nice, quick fix. The recoil on the full-sized G22 is amazingly manageable.
AND for recoil sensitive weenies, the G22 can be quickly converted to 9mm with a barrel change, basically.
I would be very surprised if the Army went with any type of Glock.
For starters, the safety is a huge issue. Imagine a scene where there are hundreds of trainees at a pistol range...some on the firing line, some in bleachers, some doing tasks associated with the range like policing brass and loading magazines.
And you are the drill Sergeant.
There is a great deal of comfort in knowing you can physically see that everybody’s pistol is on safe. With the M9, its the absence of a big red dot, visible 10 feet away. All day, your head is on a swivel, looking for big red dots. That’s life on a firing range, in the Army, if you’re in charge....one improper discharge ends your career, and depending on the damage done, the career destruction could go up the chain of command all the way to Brigade Commander. Head on a swivel...all day...no big red dots.
That comfort level is not there with a Glock. It seems minor, but its a huge deal. Special Operations type units may use it, since they are highly trained....but when your cooks and clerks hit the range to qualify, the idea of a Glock scares the hell out of me. And trainees? I just couldn’t even imagine that.
Another issue is durability. I know there is a lot of back and forth over this...and I’m sure a Glock is fine for a cop or drug agent etc, driving around in a car all day. But when you ‘live’ with a pistol, it gets banged around a lot. Climbing in and out of hatches on vehicles, crawling in dirt/mud, sweating all over it, exposing it to chemicals (our insect repellant made the plastic canteens pliable, and us mechanized guys would have antifreeze, hydraulic fluids, etc on our hands), extreme cold, oh yeah...us mechanized guys sometimes destroyed our clothes with battery acid.....anyway, I hope you get the point. There’s a reason everything in the Army is bulkier and heavier than its civilian counterpart (tents for example). The Army expects stuff to last for decades, even when being treated roughly by people with no personal ownership stake in the equipment (you would be shocked at how roughly weapons are cleaned, for example...clean gets you released for the day, so no brush is too hard).
Anyway, I’m not trying to get into the great Glock debates...but I really don’t think a Glock is suited for the Army.
