[Forte S+W]

Oh, good for them then, I thought they might have ceased production because I never see them anywhere these days. I remember that at one point they had convinced at least a few Police Departments who were already carry Glocks to adopt the .45 GAP by giving them some absurdly good deals, but as far as I know they've all since moved on.

It's honestly a shame that .45 GAP doesn't have a better niche, but then again, it was designed using an extremely common and often times success strategy of creating a new cartridge that's entire selling point is that it more or less replicates the performance of a larger cartridge. Unfortunately, by the time it had debuted, .40 S&W had already more or less dominated the Law Enforcement market, and thus a fair portion of the civilian market as well.
Nowadays 9mm Luger has become the dominant duty cartridge worldwide, and unless something happens that leads the Military/Law Enforcement to adopt another cartridge or somebody finally gets around to successfully producing an inexpensive handheld guided energy weapon, it's doubtful that will change.
