What is the .45 ACP?

The .45 ACP is a pistol cartridge developed for handguns in the early 20th century.

The .45 ACP has long been lauded as a man-stopper in its classic 230 FMJ loading, which stays subsonic, making it compatible with suppressors.

The cartridge has seen official action across two World Wars and several other conflicts, incursions, and operations since its adoption by the 1911; this battle-hardened performance keeps many older shooters loyal while attracting new ones into the caliber.

The Glock 21 is an excellent choice due to its high ammo capacity, ultra-reliable performance, and reasonable price.

I first had experience with the Glock 21 as it was my first issued duty weapon while I was in law enforcement. While my issued Glock 21 was a Gen 4 (as seen below), I got to test out the Gen 5 firsthand in many other models.

While I always thought it was rather big in my hand, I still had to buy it back when the department went to the Glock 17 for nosologic reasons.

It also has a modular backstrap that allows new owners to set it up to fit their hands better.

Choosing a .45 ACP pistol

Here are some of the most important factors when selecting your next 45 pistol.


It is important to consider the capacity of the firearm.

Best .45 ACP Pistol Magazine Capacity

Most models can hold between 6 and 10 rounds, with aftermarket magazines extending this slightly.

Glock is one of the top names in reliability and capacity for .45 ACP handguns, with models such as the G21 offering a total capacity of 14 rounds.

For concealed carry purposes, carrying 17-round magazines of .45 ACP may draw attention since they are larger than most 9 mm pistols, which can accommodate standard magazines of 15 or larger.

Barrel length

The barrel length of a .45 ACP pistol is an important factor to consider when choosing one because longer barrels are usually better for accuracy.

Short-barreled ultra-compact pistols designed for concealed carry are typically less accurate.

One consideration to remember is that modern hollow points may choke up if manufacturers haven’t optimized their feed ramp profile, so it’s important to research which guns can be used with self-defense ammo before making your purchase decision.

Finally, recoil becomes more noticeable with shorter barrels, meaning training should be a priority before using one in everyday carry.

Overall weight

Overall, weight is an important factor to consider when choosing a .45 ACP pistol because it affects the recoil of the gun and your ability to control it.

The .45 ACP is considered a heavy pistol, with most models weighing over 30 oz. This added weight can make controlling the recoil different depending on the model and weight.

Additionally, heavier pistols are more difficult to maneuver in tight spaces or while carrying them around concealed.

Weight Distribution

Weight distribution refers to the distribution of weight between different parts of a weapon.

When choosing the best .45 ACP pistol, it is important to consider the weight distribution of the pistol as it can affect your ability to handle recoil effectively.

A pistol with a larger frame will generally have more weight distributed toward its frame compared to smaller pistols, which means it will be more comfortable to hold and fire.

A larger frame provides many benefits when choosing a .45 ACP pistol for home defense, including increased comfort and stability when holding and firing the gun.

Additionally, having more space for accessories such as sights or lights helps ensure that they aren’t obstructing your grip while shooting.

Having proper weight distribution is essential in ensuring that you have control over your weapon when firing so that you don’t injure yourself or others in an emergency situation.

Frame Size

When choosing a .45 ACP pistol based on frame size, it is important to consider the advantages of having a larger frame.

These include better grip and control due to its increased weight and solid feel in your hand, as well as more space for accessories such as sights and lasers.

However, it can also be difficult for those with smaller hands to safely handle and fire these larger pistols due to their increased weight.

Additionally, smaller frames may not provide enough room for all of the desired attachments without interfering with your grip.


When considering .45 ACP pistols you should look for models that offer Picatinny or Weaver-style rails.

These types of rails can accommodate pretty much any accessory you want to mount up front and underneath the barrel, including:

  • Threaded barrels
  • New slides
  • Trigger control groups
  • Lights and lasers

Trigger Action

When choosing a .45 ACP pistol, it is important to consider the trigger action.

Many pistols in this caliber, typically the ones with hammers, offer double-action/single-action (DA/SA) or double-action only (DAO) triggers.

This doesn’t apply to sticker fire pistols like the Glocks and other polymer framed pistols.

With DA/SA triggers, your first pull of the pistol is a heavier, longer double-action pull that cocks and releases the hammer; every follow-up shot will be a light single-action pull that is crisp. With DAO triggers there is no need to manually cock the hammer before each shot.

However, some .45 ACP pistols have traditional single action (SA) triggers which require manual cocking before each shot; while this offers quick follow-up shots with minimal effort it also increases the potential for misfires if not done correctly since there is no safety mechanism in place to prevent accidental discharges if you don’t manually cock it first before pulling the trigger again.

The trigger weight is the amount of force required to fire the weapon. It is measured in pounds (lbs).


It is important to consider the sight configuration when choosing your pistol.

Most manufacturers are putting out quality pistols with rock-solid sights, and upgrades are relatively inexpensive if you don’t like the ones that came with your pistol.

45 acp sights

Suppressor height sights are perfect for those who have a threaded barrel, while standard height sights can be used with or without a suppressor or red dot sight.

On the other hand, Glock’s polymer and plastic irons are not as durable or reliable as metal sights and may not hold zero over time.

It is up to each individual shooter whether they prefer suppressor height or standard height sights depending on their preference and what they intend to use them for (such as co-witnessing with a red dot sight).

When choosing a .45 ACP pistol for home defense, there are several sights to consider:

  • Iron sights – Most manufacturers include iron sights but aftermarket sights are available
  • Suppressor height sights – Perfect for those with threaded barrels, these night sights provide a clear sight picture in all lighting conditions.
  • Backup irons – Some people prefer to have backup irons co-witnessed with their red dot or reflex sight in case the optic fails.


What is a .45 ACP pistol?

A .45 ACP pistol is a type of semi-automatic handgun that fires the .45 ACP round.

The .45 ACP round stands for Automatic Colt Pistol after the Army’s M1892 revolver which fired the .38 Long Colt Cartridge was found to be too light to stop charging Moro tribesman in the Philippines.
It quickly became beloved by both the U.S military and law enforcement professionals due to its power, as it is more powerful than 9mm rounds.

The M1911A1 pistol designed by John Moses Browning was one of the first pistols to use this new caliber round in 1921 and remains popular among shooters today due to its reliability and accuracy in various conditions.

What features should I look for in a .45 ACP pistol for home defense?

When looking for a .45 ACP pistol for home defense, there are a few key features to keep in mind:

Low recoil: The less recoil your gun has, the easier it will be to control during firing and at close range.

High magazine capacity: Ensure your chosen pistol has enough rounds to get you through any potential situation.

Reliability: Make sure your .45 ACP pistol is built with quality materials that will last years of use.

Easy handling: You want a gun that’s easy to hold and use without sacrificing accuracy or performance.

What is the difference between a .45 ACP pistol and other handguns?

Typically, the round is the only difference between .45 ACP pistols and their other caliber counterparts.

What is the magazine capacity of a .45 ACP pistol?

The magazine capacity of a .45 ACP pistol depends on the model. Most .45 ACP pistols can only accommodate standard magazines with between 6 and 10 rounds.

Aftermarket magazines may extend capacity slightly, but they add extra weight and cost. Glock is one of the top names in reliability and capacity when it comes to .45 ACP handguns, with its 21 model offering a total capacity of 14 shots.

How does the recoil of a .45 ACP pistol compare to other handguns?

The recoil of a .45 ACP pistol is often considered to be more intense than other handgun rounds, such as .40 S&W.

Many shooters find the recoil of the .45 ACP to be less pleasant than smaller rounds like the 9mm.

However, this does not mean that the recoil impulse from a .45 ACP pistol is not manageable. Many .45 ACP pistols are large and steel framed which helps absorb some of the energy from firing the gun.

What is the best holster for a .45 ACP pistol?

The best holster for a .45 ACP pistol is designed to fit your particular model.

It should be made of durable materials, such as kydex, and it should have an adjustable retention system to ensure that it stays securely in place while still being easy to draw from.

Additionally, it should have plenty of space for extra magazines or other accessories if needed.

When evaluating holsters, consider factors such as material type and construction quality; adjustability; compatibility with your specific model handgun; available space for extra mags/accessories; customer reviews/ratings; cost-effectiveness; and any special features that may be beneficial.
