What's the big deal? I've shot a couple, and yeah they seem nice, but what makes it such a big deal? What makes a 1911 any different than any other semi auto pistol?
A perfect example of the "big deal" for me is my range session yesterday.
I practiced with an HK with LEM trigger, an FN FNX, and a Colt 1911 XSE stainless.
I am having issues with weak side performance. Namely, I've lately been pushing the muzzle to the right, throwing my shots to the right of my intended impact point.
I played around with grip, a lot of dry firing, etc. and figured out my problem was trigger control. I was not pressing my trigger aft, but I was slightly pushing the trigger to the right as I did my trigger press throwing the shots off to the right. (I'm right-handed, so this is left-handed shooting).
With several hundred rounds of .22, and two boxes of .40's I got my trigger control, er, under control. It took a lot of focus to make sure I was pressing the trigger back without any side pressure. This took about two hours and cost about $90 bucks.
Oh, the 1911? Weak side I shot exactly to point of aim in one ragged hole. No problems.
The difference, and the "big deal" is that the 1911 has the best trigger of any auto-pistol, period. The 1911 trigger presses straight to the rear, as your trigger finger should for accurate shot placement. With other designs, the triggers pivot at the top, and feel heavy and clunky compared to the 1911's trigger.
Also, the ergonomics of the 1911 make it extremely easy to shoot despite the "heavy" .45 auto caliber.
The 1911 is easy to carry as well, as it is very slim.
In a nutshell: Awesome trigger, easy to shoot.
edit:
M3Stuart brought up a good point. However there are plenty of manufacturers that make great shooting 1911's right out of the box. Thanks to increased competition in the industry, more CNC machines being available, and other market forces, this stereotype of 1911's being unreliable out of the box is fast becoming obsolete. There still are some 1911 makers who produce shoddy pistols! This is a high-demand item that attracts a lot of competition. But, an informed shooter should have no problem finding a reliable and fun 1911 at a good price.
