The P944 is the current model. Both it and the P94 say P94 on the side.
I looked at this gun and while it seems fine, Ruger only produces 10 round magazines for it and I could not find any larger aftermarket mags.
This is an awfully big gun to only carry 10 rounds with and even though you might be able to find bigger mags, they will likely be used and the supply will be unreliable.
The P-95 or SR9 might a be a better choice if you want a Ruger. They carry more bullets, weighs less and are cheaper. If you want a .40 caliber, there are several excellent choices other than the P944.
I am wanting something in .40 specifically, but it also depends on what catches my eye and fits my hand well at the 1500. Heck, I might even decide to go with a revolver instead. I've just heard good things about the Ruger.
