Joe Toys does a comparison of two HK45 gas blowback pistols the compact HK45 CT  Umarex/VFC and full size HK45 from KWA... "I introduced the KWA HK45 a long time ago. This time I introduce the HK45 CT short version of the SEAL tactical pistol produced by UMAREX/VFC. The US military model MK24 Mod0 can directly accept a silencer. It is a small version of the HK45 with a smaller hand my friend believes in the size of the gas pistol, and it is very stylish."
