Is there a way to determine if a 1911 model is single or double action? I know that the true definition of a 1911 is a single stack single action pistol however, I also know that some manufacturers make a double action 1911. To that end, what signs/characteristics should I look for to differentiate between the two?

If the trigger can be pulled while the hammer is down, it's crap.

If it cannot, it is single action.

The smaller hammer that you can't cock back with your thumb and the aura of shame surrounding it.

IIRC, if it's double action then it's only styled as a 1911 - but has completely different internals.

You can tell if any pistol is double action simply by pulling the trigger while the hammer is uncocked. If pulling the trigger causes the hammer to lower then strike, it is double action. If it does nothing, then it is single action.

1911's are single actions. Para Ordnance makes a a double action only called LDA. You can tell by the trigger. SA triggers pull straight back while the DA trigger is on a hinge.

DA guns have a trigger that pivots on a pin, like a revolver.

SA 1911's have a trigger that pushes straight back...look at a picture.

This.

The original 1911 design is that of a single-action.
That's not to say that you have to manually cock it each time you fire it like you do with a SA revolver... that is taken care of for you by the slide.

The above statement is incorrect, there are SA only pistols that have triggers that are hinged at the top and pivot to the rear on its axis.
The only way to tell for certain is to manipulate the action.

If the trigger only drops the hammer then it is a single action.
Double action means the trigger controls 2 actions, it (1) cocks the hammer then (2) it drops the hammer.

That is what single action and double action mean. Most 1911's are single action.

Drop the hammer.

Pull the trigger.

If the hammer moves rearward and then drops, then it's shameful on a "1911" and double action.

If nothing happens, it's single action.
