The Colt-45 or Colt M1911 respectively, is a single-action, semi-automatic handgun and usually the first weapon which Adam finds upon embarking on his journey through the Realms of the Haunting. However, if he doesn't pick up the Colt-45 which lies next to the Typewriter in the Mansion's Cabinet Room, he will find a second one (along with 2 Magazines) after entering the Mausoleum. Just when the hallway back to the Study becomes blocked, a little niche opens up with the gun inside. When returning to the typewriter room, the original Colt-45 will still be there. Nota bene that I became aware of this secret thanks to Disthron's playthrough of the game:
The Colt-45 was designed by John M. Browning, and was the standard-issue side arm for the United States armed forces from 1911 to 1985, and is still carried by some U.S. forces. It was widely used in World War I, World War II, the Korean War and the Vietnam War.

- Cartridge: .45 ACP;
- Barrel: 5 in (127 mm) Government, 4.25 in (108 mm) Commander, and the 3.5 in (89 mm) Officer's ACP. Some modern "carry" guns have significantly shorter barrels and frames, while others use standard frames and extended slides with 6 in (152 mm) barrels
- Rate of twist: 16 in (406 mm) per turn, or 1:35.5 calibers (.45 ACP)
- Operation: Recoil-operated, closed breech, single action, semi-automatic
- Weight (unloaded): 2 lb 7 oz (1.1 kg) (government model)
- Height: 5.25 in (133 mm)
- Length: 8.25 in (210 mm)
- Capacity: 7+1 rounds (7 in standard-capacity magazine +1 in firing chamber); 8+1 in aftermarket standard-size magazine; 9+ in extended and hi-cap magazines/frames guns chambered in .38 Super and 9mm have a 9+1 capacity. Some models using double-stacked magazines, such as those from Para Ordnance, Strayer Voigt Inc and STI International Inc have significantly larger capacities. Colt makes their own 8 round magazines which they include with their Series 80 XSE models.
- Safeties: A grip safety, sear disconnect, slide stop, a half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911A1s. Several companies have developed a firing pin block. Colt's 80 series uses a trigger operated one and several other manufacturers (such as Smith & Wesson) use one operated by the grip safety.
- Grip safety deactivation: A problem for some shooters is that they have trouble deactivating the grip safety when they hold the gun. This primarily affects shooters who have small hands. It can also occur when a shooter places his thumb on top of the thumb safety, which tends to reduce pressure on the grip safety. To rectify this problem, a number of grip safety manufacturers have designed safeties with extended ridges, so that when a shooter grips the gun, his hand will come into contact with the ridges and deactivate the safety (i.e., allowing the gun to fire). Some instructors find this "problem" to be a result of poor hand placement, since an 11 year-old was documented able to do so, or worn safety components, known to both military and civilian armorers and systematic checks are to be made to verify its functionality.
