OK, here's my take... I have a love-hate relationship with the things, more love than hate...
Pros - Too many to list without overrunning the character count, but I'll highlight a few.
-Best trigger. Customizable, doesn't suck, easiest to shoot... ever.
-Low, if not, the lowest, bore axis. Excellent recoil/flip control.
-Customizable in general- there are more aftermarket parts for these things than all other gun makes combined.
-Fits most people's hands very well. Most guns have crappy ergos compared to a 1911.
-Often is most natural point of aim of any handgun for lots of users.
-Can be made really, really, accurate.
-Optics and compensators are not exotic items for a 1911.
-Several guys locally can repair/mod without having to ship. Makes life easier.
Cons -
- F**king s**ty ass plunger tube design. (Some guns have it integrated, about time)
- F**king swinging link design. Hint: There's a reason the Browning Hi Power doesn't have it.... Browning or Dieudonné Saive decided the swinging link thing sucked ass and got rid of it. Thank god.
- F**king controlled feed design.... which creates reliability issues, and is part of the reason why there is no one gold
standard 1911 mag that reliably feeds all kinds of ammunition in all 1911s. Can be overcome, but it is annoying.
- Lame manufacturers that don't do it right and sell broken 1911s. (EG, garbage like the springfield micro and the Para Warthog.... come on people... cut me a break here. Those are not 1911s, they're crap. )
- Poorly done up double stack 1911s. Para being the worst offender, there are others. Most have to be "gunsmith specialed" to make them work right. Magazine tuning? Blech. What a friggan mess.
- Some 1911s have a low reliability overhead. If your gun is tight, you can forget pouring 500+ down the pipe without
at least some form of clean and lube job.
Before anyone flames the crap out of me... despite all the above... I own a couple of 1911s and want to buy more. The benefits still generally far outweigh the inherent flaws of the design. It's not flawless but no handgun is. Some well done
1911s are pretty close to that standard, though.
