Characteristics and Ballistics

The 45ACP Canada cartridge, famed for its distinctive automatic colt pistol design, also known as the 45cal, is known for its robust design and large bullet diameter of .451 inches (11.45mm). Its weight typically ranges between 185 to 230 grains, with variations available for different purposes. The 45ACP Canada exhibits moderate recoil, making it manageable for most shooters and its muzzle energy provides excellent stopping power, derived from its pressurized cartridges, known to the gun 45.

Legalities and Restrictions

In Canada, firearm regulations are governed by the Firearms Act and its accompanying regulations. The 45ACP Canada, even in an fmj round, is classified as a restricted caliber, which means it is subject to stricter regulations compared to non-restricted firearms. Owners of firearms must hold a valid Possession and Acquisition License (PAL) with restricted privileges, adhere to safe storage requirements, and comply with transportation rules.

Popular Firearms Chambered in 45ACP

Despite the regulations, many Canadian gun enthusiasts favor firearms chambered in 45ACP including a variety of revolvers. The Glock 21, SIG Sauer P220, and 1911-style pistols from various manufacturers are among the popular choices. These firearms offer a combination of reliability, accuracy, and ergonomics, making them highly suitable for self-defense, competition shooting, even serving as a target for advanced shooting practice, and hunting.

Stopping Power

One of the primary advantages of the 45-ACP is its stopping power. The larger bullet diameter and slower velocity create a greater wound channel, increasing the likelihood of incapacitating an assailant quickly and effectively. This characteristic makes the 45-ACP, also referenced as the .45, a popular choice for personal defense and law enforcement applications.


For Canadian individuals seeking a reliable self-defense option, the 45-ACP provides peace of mind. Coupled with its full metal jacket (fmj) cartridges, its ability to neutralize threats efficiently, combined with proper training and shot placement, offers an added layer of protection for individuals concerned about personal safety.

Despite the 45ACP not typically being the first choice for hunting due to its limited range and bullet drop, it can still be suitable for certain scenarios. In Canada, where hunting regulations may vary by province and game species, the 45-ACP with its enforced case for improved pressure handling, can be used for hunting small to medium-sized game at closer distances. However, it’s crucial to check local hunting regulations and ensure that the 45-ACP meets the legal requirements for specific hunting activities.

Disadvantages of .45-ACP


One of the notable drawbacks of the 45-ACP is its recoil. Due to the larger bullet size and relatively lower muzzle velocity, shooters may experience more recoil compared to other calibers. This can affect accuracy, especially for inexperienced shooters or those with limited upper body strength. But despite these, the 45ACP, especially when it is in an fmj round, still holds a prominent place in the world of firearms, particularly in Canada. Proper grip and stance, as well as regular practice, can help mitigate the effects of recoil. This becomes particularly relevant when discussing the subtleties between 9mm vs 45, two popular handgun calibers.

Magazine Capacity

Another consideration with 45-ACP firearms, a version of guns that is often a hot topic among enthusiasts, is their magazine capacity. Due to the size of the cartridge, and its specific primer type, firearms chambered in .45 ACP often have lower magazine capacities compared to smaller calibers like 9mm and NATO cartridges. This “45 caliber vs 9mm” capacity battle, for example, is a frequent topic among firearm enthusiasts. The gap in capacities, in essence, means fewer rounds per magazine and potentially more frequent reloading. This difference in ammunition amount can be critical if you’re considering a 45th gun, which employs the .45 long colt caliber, named for its larger base diameter. While this may not be a significant concern for certain applications, such as home defense or police use, especially when wielding a 45 colt, it’s worth noting for those who prioritize higher ammunition capacity.


The cost of ammunition is an important factor to consider for any firearm enthusiast. Unfortunately, the 45-ACP tends to be more expensive compared to other popular calibers, notably the 9mm, with the “.45 versus 9mm” argument often swinging towards the latter in terms of cost-effectiveness. This higher cost can impact regular shooting practice and training sessions, especially for individuals on a budget or police departments managing public funds. The debate over “45 acp vs 9mm” gains additional traction when cost and penetration ability come into play. It’s essential to factor in the cost of ammunition when considering the long-term affordability of owning and shooting a 45-ACP firearm.

When embarking on the buying process for 45-ACP firearms, or even when trying to decide between “45 or 9mm”, several key factors should be deliberated:

Online forums and trusted firearm publications can provide valuable insights into the performance and reputation of specific firearms chambered in 45 ACP, or even when comparing “9mm vs .45 caliber”.

Fit and Comfort

Whether you’re an enthusiast, a security professional or a member of the police force, it’s crucial to find a firearm that fits comfortably in your hand. Visit a local gun store or shooting range to test various models and determine which ones provide the best ergonomics and grip for your personal preferences. Finding a comfortable and secure fit can enhance accuracy and shooting enjoyment, whether using a caliber 45 or a 9mm.

Reliability and Durability

Whether you’re picking up a gun for home defense, police work, or sport, look for firearms known for their reliability and durability. The ability to consistently feed, fire, and eject rounds without issues is vital for guns of any kind, especially for self-defense purposes. Research the reputation of different manufacturers and models to invest in a firearm that will serve reliably over time, regardless of your preference in the “9mm vs .45” debate.

Despite the legal restrictions and considerations associated with owning firearms chambered in 45-ACP, enthusiasts appreciate the exceptional stopping power, penetration capabilities, and hunting potential offered by this caliber. Understanding the advantages and disadvantages, whether it may be in the context of “45 acp vs 9mm” or within the .45 caliber itself, as well as conducting thorough research before purchasing a 45-ACP firearm, can help individuals make informed decisions based on their specific needs and preferences.
