Right

Being issued and in service, does not mean it was successful nor does it mean it was ideal. Don't forget, big green rarely uses pistols so saying that 1911's hanging off the side of an officers belt or a machine gunners for decades is evidence of "solid performance" is a bit ignorant. Many here need to drop the "iron and wood" mentality and objectively compare a 100 year old design to modern designs. The comparison between old and new isn't even a contest. 1911's are beyond their time. Same goes for the desire for a full ambi pistol. Completely unnecessary if you apply a modern manual of arms. Ambi guns, interchangeable backstraps and the plethora of "custom" 1911 finishes/styles/colours/packages etc are nothing but marketing. Geared for the civilian plinker and poser extraordinaire. All useless gimmicks that serve no practical purpose. Most have no positive effect on performance or reliability while others give the illusion of improved performance. Then again, when the majority of users/owners have no defined purpose for the firearm, and thus fail to apply any sort of criteria behind their purchase. Selling such crap isn't much of a challenge. Add in the fact that approximately 1%(or less) of users/owners have any sort of formal training, and the challenge of selling such products gets easier and easier.
I have to question why someone would seek a full ambi gun? Any quality/reputable school is more than capable of teaching proper functioning of the gun with either hand without the advent of ambi controls, to both left and right handed shooters. Lefties have been coming up with effective methods of operating predominantly "right handed"( I say "right handed" as the standard setup is presumed to be ideal for righties. The reality is that some "right" guns are setup more for lefties such as SIG pistols and VZ/CZ 58/858 rifles) tools since the dawn of time. Furthermore, if you don't intend to compete, train, or use your pistol for personal defence, then why do you need an ambi gun? What's the rush to reload or unload? There's no time limit when a ceasefire is called on the line. Seeing as how most guns are not full ambi in their controls, wouldn't learning on one make it a specialized skill unique to that make and model?
Here's the breakdown of logic for wanting/needing an ambi gun
Want ambi but have no training= no idea what you want or need, victim of marketing hype
want ambi but have no desire to compete/train/PD= No practical need for such attributes
Want ambi and have training= Your training sucks or you've chosen to ignore practical knowledge
Want ambi and wish to compete/train/HD(or do)= Your training sucks or is abscent, and you'll see no appreciable gain in performance as in time and/or score. No idea what you need.
