Hi wmg1299,The XDS Mod.2 in .45 is small and thin enough to be concealable, but just big enough to provide adequate control. I'd recommend checking it out to see if it meets your standards.
If it's a .45 ACP, it exceeds my standards.
I'll cop to never firing a striker-fired .45 ACP. However, light target loads are a blast to shoot out of a 1911-A1. I have no clue whether ammo manufacturers still market light .45 ACP target loads of 185 grains.
While nothing has diverted me from my belief that the .357 Mag is our most versatile cartridge, likewise I continue to believe that the .45 ACP is our best cartridge. It is inherently accurate. At one time, it was the handgun competitors' handgun. With light loads, its weight causes recoil to become a nonissue, which is an important issue for kids. The more kids enjoy shooting sports, the more likely our sport and hobby will grow.
Light target loads = less stress on handguns, not that stress is an issue with Springfield Armory's forged steel 1911-A1s.
In all honesty, I haven't seen .45 ACP target loads in a long time. Are they still marketed?
I have no clue why shooters buy cases of +P self-defense ammo. A box of fifty will last generations. 99.9% of shooters who stockpile +P (excluding law enforcement) wind up shooting them at targets.
I will agree that every so often it is a good idea to put a box of self-defense ammo through a self-defense handgun. It's better to ID a possible problem long before confronted with a potential tragedy.
