If your HK45 takes .45ACP ammo, it's another 1911 copy. DUH
The HK45 is merely an upgrade to the USP45, per the HK website!! DUH
"The HK45 was developed as a product improvement of the highly regarded USP45, first released in the 1995. The Caliber .45 ACP HK45 includes several user-inspired enhancements including changeable grip panels (backstraps), a Picatinny MIL-STD-1913 accessory rail, better ergonomics, and more ambidextrous controls."
•HK45 grip-to-slide angle matches Model 1911’s profile
Right from the HK website!! LOL
People as dumb as yourself shouldn't be allowed to own a gun they know nothing about.
There is a lot more than a grip to slide angle that makes this weapon.
Trust me. It is NOT a 1911 even though it shares the grip to slide angle and uses the same ammo.
There are lots of weapons that use .45 caliber acp ammo. That does not make them a 1911.
You are full of shit.
