Not sure I understand your response.
Even if there were only one option for a pistol............it would still cost money.........so saying that the problem with a little variety, with having a caliber that some may deem unnecessary, is money.........confuses me.
The .45 GAP offered nothing but a smaller grip, which apparently many people don't consider reason enough to buy guns in that chambering. It offered no performance gains over the .45 Auto, unlike the .327 Magnum over previous .32 caliber cartridges.
If you don't like the new .327, that's your choice, but it doesn't mean I can't like it, or use and be perfectly happy with it..........even though I have a .357 revolver too.
