One of the best clues in determine if a powder will be any good with a particular cartridge is to check published load data, esp from the powder manufacturer as they have the most vested interest in getting customers to use their product.

There is NO data showing a .44 spl load using AA#9 in the current accurate publications of load data for their powders.

Slow pistol powders are for high pressure large capacity magnum pistol cartridges and small case rifle cartridges. AA( is too slow to be useful in the low pressure .44 spl cartridge. The slowest burn rate powders you find are AA7, Blue Dot and similar. With exceptionally heavy bullets you find a couple loads using 2400. If you can find AA9 data for the .44 spl from a reliable source then go ahead and try it. Let us know how it works though it isn't the best powder for low pressure.

For the .44 spl use fast powder like AA2, Bullseye, Red Dot, W231/HP38 for target loads. For defensive and game loads use powders no slower than Blue Dot, AA7. Medium burn rate powders are better suited like Unique, AA5, Universal, etc.
