The Glock 21 does fire the .45 ACP, as does the Glock 30. You're probably thinking of the Glock 37, 38, and 39, which fire the .45 GAP cartridge - those cannot fire a .45 ACP.
Nothing, because it doesn't exist. The Glock 30 is chambered for 45 ACP. Values range from 100-600 USD
Both. .45 Auto and .45 ACP are the same round.
.45 ACP
If you mean the Glock 36, it's 45 ACP.
IF truly NIB, 550 USD
Aside from the uncommon .45 GAP chambered Glocks, yes. Check the marking on your barrel for the .45 ACP marking.
ACP means Automatic Colt Pistol. .45 ACP and .45 Auto are the same cartridge. .45 Colt and .45 Auto Rim are a revolver cartridge. .45 GAP (Glock Auto Pistol) is a shorter round than the ACP, and does not interchange with it.
Glock pistols are made in a variety of calibers. Currently available in .380 ACP, 9mm Luger, .357 Sig, .40 S&W, 10mm Auto, .45 ACP and .45 GAP.
When comparing the power of a .357 Glock and a .45 ACP Glock, it's important to consider several factors, including muzzle energy, bullet weight, and ballistic performance. Generally, the .357 Magnum cartridge is known for its higher muzzle energy compared to the .45 ACP cartridge. Here's a brief overview: **.357 Glock:** The .357 Magnum cartridge is a powerful and high-velocity round. It typically offers higher muzzle energy compared to the .45 ACP. The .357 Glock, often chambered in the Glock 31 or Glock 32, is known for its effective stopping power and flatter trajectory. **.45 ACP Glock:** The .45 ACP cartridge is known for its larger bullet diameter and heavier bullets. It has a reputation for delivering substantial stopping power. The .45 ACP Glock, like the Glock 21 or Glock 30, is appreciated for its recoil management and the classic "big bore" punch. In terms of sheer power and velocity, the .357 Glock may have the edge. However, factors such as recoil, capacity, and personal preference also play a significant role in choosing a handgun. Some shooters prefer the heavier, slower recoil of the .45 ACP for its controllability, while others prefer the flatter trajectory and higher velocity of the .357 Magnum. Ultimately, the "power" of a handgun is a subjective consideration that depends on the specific needs and preferences of the shooter. It's recommended to try out different calibers and models to determine what works best for you in terms of accuracy, recoil control, and overall shooting experience.
Nope. Matter of fact, you can't even load it. The .45 Automatic Colt Pistol (ACP) cartridge is longer than the .45 Glock Automatic Pistol cartridge (GAP). And the model 37 IS in .45 GAP. Both rounds headspace off the case MOUTH- the .45 ACP is too long for the slide to go into battery (close the action). And, with the exception of some revolvers, you cannot shoot .45 GAP in an .45 ACP firearm.
The .45 GAP is a shorter cartridge than the .45 ACP. Developed for the Glock Automatic Pistol (that's the GAP) it does not interchange with the .45 Colt Automatic Pistol (ACP). Made for a smaller firearm, shorter action, etc.
