I shoot (guess what) the 1911 more often than not.
If I remember correctly, the Stoeger Cougar is a traditional-double-action (TDA) pistol, which means that the user has to transition from a double-action (DA) first shot to single-action (SA) subsequent shots.
Shooting a pistol is difficult enough. In my mind, it makes no sense to complicate an already-difficult learning curve with such a confusing transition. I suggest that using a pistol with a single, consistent trigger action is a much better choice.
The 1911 is a single-action (SA) semi-auto, and every shot is fired in exactly the same manner. However, when using a SA semi-auto, strict attention must be paid to the gun's safety lever. This is particularly true since the SA pistol is carried loaded, cocked, and on safe.
Learning to use a SA semi-auto is the easiest of all of the options available to the pistol shooter, even including the safety lever and its manipulation.
There is one more option worth considering: The double-action-only (DAO) pistol. In this case, every shot is fired in the same way, but each trigger press is long and somewhat hard. This trigger action replaces the safety lever, giving the learner one fewer thing to think about.
Although it is not strictly a DAO pistol, a good example of this type is Glock's "safe action." In this type of gun, the trigger pull is neither particularly long, nor particularly hard. Other, true DAO pistols are somewhat more difficult to master.
You might add the Glock, the Springfield, and the S&W (as well as others) to your list of pistols to consider.
