The 357sig has been available for quite a while now but still this cartridge is not available locally, that's for me though since i haven't seen any. I think the 45GAP will have a better chance of getting here once it picks up in the States. You already know the filipino romance with the 45.
One of my fellow gunclub member shoots a Glock31 (.357sig), former revolver shooter eh kaya bilib sa .357 caliber ;f ;f ;f
Medyo hirap nga daw kumuha ng shells for his reloads. His reloader necks down a .40S&W shell for him. The barrel of his G31 and my G22 are interchangeable, and so are our magazines. ;f
