The HK45C, or Heckler & Koch HK45 Compact, is a compact pistol designed by German firearms company Heckler & Koch in the early 2000s. It fires the large .45 ACP cartridge and can utilize 8 to 10 round magazines. It features an ergonomic design and has many more tactical options compared to earlier HK models. The Tactical variant includes a threaded barrel for use with barrel modifications like Suppressors, a picatinny rail, and customizable backstraps to better fit a shooter's hand.
Like the M1911, it has moderately high damage, taking 3-7 hits to kill. Compared to the M1911, it has the advantage of three more rounds in its magazine and a faster rate of fire by 10 rounds per minute, but the M1911 is much more accurate with slightly lower recoil.
Like the MP-443, M1911 and FN57, its recoil kicks straight up, and very little to either side. This makes the Compensator largely unneeded, while the Muzzle Brake could be useful for reducing vertical recoil.
Before the Fall patch, its low muzzle velocity of 250 m/s was worsened to 160 m/s with Suppressor, reducing its effectiveness at range.
After the Fall patch, its unsuppressed and suppressed muzzle velocities have been increased to 270 m/s and 230 m/s, respectively.
The 45T is a sidearm featured in Battlefield Hardline.
The 45T can first be found on an enemy during the building raid at the end of the third episode. Once it has been picked up, it can be selected for the player's loadout in any episode.
- During the game's June Beta, the 45T was originally named the HK45C, the weapon's name in real life. It was possibly renamed to avoid copyright issues with Heckler and Koch.
