45 Gap Glock - 45 ACP (aka 45 Auto) is here to stay. As the standard ammunition for the M1911 pistol, which has been used in the US Armed Forces for more than 110 years, the 45 ACP is part of America's .45 caliber pistol cartridge.

It only follows that the ACP 45 must have a large devoted following. And no. As a commenter on the M1911 forum once said, "We're called boomers because our guns boom." 45 ACP fans will go to the next round quickly from asking for spaghetti for Thanksgiving dinner.

45 Auto is a slightly larger cartridge, but both calibers perform equally well in most pistols. 45 GAP is harder to find when it comes to ammo and generally more expensive to shoot. Due to the difference in ammo size, these two calibers are not interchangeable in pistols.

All this means that Glock in 2003 introduced the 45 GAP. Inspired by the success of shortening (and shortening) the previous 10mm into the 40 S&W, Glock decided they could emulate it by introducing a shortened version of the 45 ACP.

The 45 GAP actually hits the mark with a barrel that is .143 inches shorter than the 45 ACP. 45 GAP can do this without sacrificing performance because it is designed for today's powder. Modern powder is smaller than Browning's powder at the turn of the century. Glock also reinforced the case to reduce the chance of the neck exploding. They didn't try to make the 45 GAP pistol more powerful than its predecessor.

This is where Glock went wrong. 40 S&W became popular due to its comparable performance to the light 10mm loads of smaller pistols. However, the G37 pistol chambered in 45 GAP is only half an ounce lighter than the 45 ACP G21!

Compared to the Glock 40 S&W pistol, which is 7 ounces lighter than the 10mm model, you can better tell how the Glock releases the ball. They shrunk the cartridge but didn't shrunk the firearm to suit their purpose.

45 GAP failed. If there are still law enforcement agencies still using it, it won't be used for long. Many private citizens use it. If you are thinking of buying a 45 GAP handgun, go to know that finding the ammunition you want can be frustrating.

Besides all that, we have to ask: Does the 45 GAP do the same thing as the 45 ACP, just in a smaller package? Let's compare ballistics, stopping power, and recoil to see how the Glock stacks up against the 45 ACP.

Outwardly, the 45 GAP is essentially a shorter version of the 45 ACP ammunition: the same bullet pressure and chamber, and both contain less copper. The shorter case of the 45 GAP is no different from modern powder. So, on paper, there's no reason why we should expect these two rounds to perform any differently. But how is it in practice?

We tried to choose the most apples-to-apples rounds to compare head-to-head, one for each 45 GAP and 45 ACP common bullet weight: 185, 200 and 230 grains. As our ballistic data shows, both rounds actually deliver the same ballistic results. The muzzle velocity of the No. 45 GAP round is significantly different from the equivalent weight of the 45 ACP. Bullets may roll faster in one round or another just depending on the weight of the bullet.

This is a great place where the 45 ACP offers an advantage that the 45 GAP does not: overpressure ammunition. The 45 ACP + P cartridge may pack more punch, but it will also provide a flatter trajectory that will gain more kinetic energy. In theory you can open 45 GAP + P. To our knowledge, it has never been produced commercially.

Several factors determine how effectively a cartridge can neutralize a threat. Because 45 ACP and 45 GAP fire essentially identical bullets, they have the same initial winding channel diameter and sectional density (which represents the bullet's penetration potential). But the amount of energy a bullet can transfer to a target on impact is probably the most important factor in stopping power.

45 GAP is superior to its predecessor in terms of energy impact. Depending on the company that makes the ammo, you may find that the 45 GAP or 45 ACP will have a harder time hitting the target.

It should be noted that the 45 GAP, despite Glock's intentions, is often seen as a slightly weaker version of the 45 ACP. We do not notice, although there is no need to argue with those who have.

None of these calibers are considered favorites for long range use. We include this table more out of morbid curiosity than any real practical use cases. You can see that the 45 ACP and 45 GAP are pretty similar when it comes to bullet drop from 100 meters.

For self-defense, it is better to use a pistol with a lighter recoil. They make a relatively low flip, which in turn facilitates quick and accurate fire. In other words, when the threat increases and you miss the first shot, you want to spend as little time as possible on the second shot. If they weren't sure before, the first shot at the threat proves that it's either them or you.

Comparing the recoil energy of the six rounds mentioned above is easy. We already have bullet weight and muzzle velocity; now all we need is the missile and the weight of the firearm. For comparison, say the 45 ACP round has six grains of powder and the 45 GAP has five. Also, 45 ACP rounds fired from the 29.28 oz G21 gun; 45 GAP ammo, 28.75 oz G37 gun.

Quote: These two cartridges produce nearly identical recoil energy. You may notice a slight difference between the two. Of course, a heavier handgun will always reduce felt recoil, but you won't benefit from a significant reduction in recoil by choosing one cartridge over another.

After the 9mm, the 45 ACP is the second most popular centerfire pistol cartridge in America. So, as far as pistols go, the 1911 makes finding 45 ACP ammo as easy as going online or to a sporting goods store. Also, 45 ACP firearms are not more expensive than the market will allow.

45 GAP is another story. You can easily buy a G37 because Glock still makes them. But finding 45 GAP ammo—let alone a lot of 45 GAP rounds—can be a pain. The demand for 45 GAP simply isn't high enough for ammunition manufacturers to continue to provide raw materials for production. So even in the best of times, the pickings can be slim.

In general, the 45 GAP performs the same as the 45 ACP. It can be as accurate, powerful and easy to control as its predecessor. However, the 45 GAP is simply not enough for shooters to transition from well-established and popular rounds.

45 GAP will be around for a while, but hopefully it will be out of production. Years from now, it will live on as nothing more than a curiosity among handloaders who like to build cartridges to exact specifications.

We don't think we can say it any clearer: don't buy a 45 GAP gun. The 45 ACP does all the new cartridges, just a thousand times and never loses. The Glock 39 is a small gun that fires big bullets that may not be well-known, but emergencies can save you: At the beginning of the 21st century, an industrial collaboration between CCI/Speer Ammunition Company and Glock led to the development of a new caliber, the .45 GAP. GAP stands for Glock Automatic Pistol and is intended as an alternative to the nearly century-old .45 ACP. Despite its problems, the .45 GAP is still an ideal cartridge for shooters who want power with recoil.

.45 rounds of GAP in 2002. published by CCI / Speer in November. This round was developed by Ernest Dunham in response to a request from Glock to make a round that would have the same overall length as the 9mm Luger with the raw power of .45 ACP. 9mm Luger, also known as 9 × 19, has an overall length of 29 millimeters, while the .45 ACP is 32 millimeters.

While Glock has developed new calibers, including the .40 Smith & Wesson, the new rounds will allow compact and non-compact pistols to carry high firepower while maintaining overall length, especially grip length. Grip comfort is key when choosing a firearm, and a grip that's too wide can hurt you
