One possibility is to buy one of the surplus Beretta 82's that are for sale on so many of the surplus websites right now. They are around $200 plus shipping and FFL charges. It is a 32acp pistol. IIRC, it holds 12 rounds. It would be very easy to use for a course, since it is an extremely well-made pistol with extremely low recoil.
If and when the OP felt comfortable with the Model 81, a Model 84 could be purchased. The Model 84 is not as inexpensive, but it is identical except that it is in 380acp caliber. I think mine cost somewhere in the mid $300's used, though it took some patient haunting of Gunbroker to find it for that price.
Also, the Models 81 and 84 feel and handle a lot like the Model 92, other than being smaller (maybe 2/3 or 3/4 sized). The OP could first become comfortable with the inexpensive Model 81. After that, if a Model 92 compact fit his hands well enough, it would be an extremely easy transition.
It's just a random thought I had. I have an 81, 82, 92, and 96. They are all very nice handguns.
I put aftermarket grips on my 81 and 84 to fit my XXL hands better. The 84 has a lot of finish wear. It was some kind of military surplus. The 81 is dirty in this picture, but it seemed to have barely been shot before I got it.
My Model 96 (40 caliber) was also military surplus. I got it for an outrageously low price due to it being a "Frankenstein gun" made of non-matching frame and slide. You can see the family resemblance to the two above.
