Can I Shoot 40 Cal In A 10mm?

No, you cannot shoot 40 cal in a 10mm handgun. Because the 10mm is a slightly larger caliber than the 40 cal and the two are not interchangeable. While the 10mm is a powerful cartridge, the 40 cal is even more powerful and would cause excessive wear and tear on the 10mm handgun.

For your better understanding, I am going to discuss over 40 cal and 10mm ammo design, quality, and specifications, the firearms where you can use these ammos, whether you can shoot 40 cal in a 10mm pistol, whether is it safe to shoot a 10 mm from a .40 S&W pistol, and so many relevant matters to this. Let’s start our voyage.

 

The Quality, and Specifications Of 40 Cal & 10mm Ammo

40 Cal Ammo:

The 40 Caliber or 40 S&W (Smith and Wesson) is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester.

  • It uses 0.40-inch (10.16mm) diameter bullets ranging from 135 to 200 grains.
  • The energy of the 40 Cal is between 350 and 500 ft/lbs depending on the load, bullet weight, and powder charge.
  • The muzzle velocity is usually between 950 and 1400 fps.
  • The 40 Cal is popular for self-defense and is widely used for law enforcement and military applications.

Things To Consider.

  1. The 40 Cal is a straight-walled cartridge with a case length of 0.850 inches and an overall length of 1.135 inches.
  2. It is significantly shorter than the 10mm and less powerful than the 45 ACP.
  3. The 40 S&W is commonly loaded with hollow-point, full metal jackets, and frangible bullets.

10mm Ammo:

The 10mm Auto is a rimless, straight-walled pistol cartridge developed by Jeff Cooper and introduced by firearms manufacturer FN Herstal in 1983.

  • It uses a 0.401-inch (10.2mm) diameter bullet ranging from 135 to 200 grains.
  • The energy of the 10mm is between 400 and 700 ft/lbs depending on the load, bullet weight, and powder charge.
  • The muzzle velocity is usually between 1200 and 1600 fps.
  • The 10mm is popular for self-defense. And it is also widely used for law enforcement and military applications.

Things To Consider.

  1. The 10mm is a straight-walled cartridge with a case length of 0.992 inches and an overall length of 1.280 inches.
  2. It is slightly longer than the 40 S&W and more powerful than the 45 ACP.
  3. The 10mm is commonly loaded with hollow-point, full metal jackets, and frangible bullets.

 

What Firearms Use 40 Cal And 10 mm Round?

The 40 S&W and 10mm Auto are both pistol cartridges commonly used for self-defense and law enforcement. Popular handguns chambered for these rounds include-

  • the Glock 22, 23, 27, and 35,
  • the Smith & Wesson M&P series,
  • the SIG Sauer P226 and P229,
  • the Beretta 92FS and 96A1,
  • and the 1911A1.

Digest

Rifles chambered for the 10mm Auto include the Kel-Tec Sub 2000 and the AR-15 (using a conversion kit).

The 40 S&W is less common in rifles, but there are some such as the Beretta CX4 Storm, the Ruger PC Carbine, and the Kel-Tec SUB-2000.

What Other Caliber Pistol Will The 10mm Round Work With?

The 10mm round will work with nearly any pistol chambered for .40 S&W and .357 SIG, as those calibers use the same diameter bullet.

While the 10mm round has a higher pressure, those calibers can typically handle it without issue. Some models of Glock pistols, such as the Glock 20, are available in a “10mm Auto” chambering, which is designed specifically to handle the 10mm round.

 

Well, Can I Shoot 40 Cal In A 10mm?

No, you cannot shoot 40 cal in a 10mm firearm.

As the two cartridges have different dimensions, the 40 cal round will not fit in the chamber of a 10mm firearm. Also, the 10mm is a semi-automatic round and the 40 cal is a revolver round.

Moreover, revolver rounds are not designed to be fired from semi-automatic firearms. Therefore, attempting to shoot 40 cal in a 10mm firearm could result in serious damage to the firearm and possible injury to the shooter.

Shooting 40 s&w In A 10mm Hi-Point Carbine

Shooting 40 S&W in a 10mm Hi-Point Carbine is not advised and should not be attempted.

The barrel and chamber are not designed for 40 S&W ammunition, and the carbine is not built to reliably cycle it. Also, the higher pressures of the 40 S&W could cause excessive wear and tear on the action. And it could also cause a dangerous situation if the ammunition is not loaded properly.

Also, Can I Shoot 40 Cal In A 10mm 1911?

No. A 10mm 1911 is designed to handle 10mm rounds, and a 40-caliber round is too large to fit in the chamber of the gun. Additionally, the 10mm round has a much higher pressure than the 40-caliber round, so shooting a 40-caliber round in a 10mm 1911 would likely cause damage to the gun, and could potentially be dangerous.

 

Is It Safe To Shoot A 10 mm From A .40 S&W Pistol?

No, it is not safe to shoot a 10mm from a .40 S&W pistol. The .40 S&W is designed to fire .40 S&W rounds, not 10mm rounds. The 10mm is a larger, more powerful round and can cause the gun to malfunction or even explode.

Additionally, the 10mm round is not designed to fit correctly in a .40 S&W pistol, so the round may be too large to chamber correctly. As a result, the bullet may become stuck in the barrel or cause a catastrophic failure of the pistol.

Does 10mm Have More Noticeable Recoil Than .40 S&W?

Yes, 10mm has more noticeable recoil than .40 S&W. This is due to the fact that the 10mm round generates more energy and has a higher muzzle velocity than the .40 S&W round.

  • The 10mm round has a muzzle energy of 540-750 ft-lbs, while the .40 S&W round has a muzzle energy of 400-550 ft-lbs.
  • The 10mm round also has a higher muzzle velocity, with a range of 1250-1450 fps, while the .40 S&W round has a muzzle velocity of 1000-1250 fps.

Therefore, when fired, the 10mm round produces more recoil due to its greater energy and velocity.

Can I Shoot 40 S&W In A 10mm Glock?

No, you cannot shoot .40 S&W in a 10mm Glock.

The chamber and barrel are of different dimensions, and the .40 S&W round will not fit properly into a 10mm Glock chamber.

Should I Shoot .40 S&W Ammunition With My Unmodified 10mm GLOCK 20 Pistol?

No, you should not shoot .40 S&W ammunition in an unmodified 10mm GLOCK 20 pistol.

Shooting the wrong ammunition can cause the gun to malfunction and even rupture, potentially causing serious injury. The 10mm GLOCK 20 is designed for 10mm ammunition only and must not be used with any other type of ammunition.

 

Before I Go

It is clear that you cannot shoot 40 cal in a 10mm as the two calibers are not interchangeable and using the wrong caliber could be dangerous. The 10mm is designed to handle the higher pressure and size of the 10mm rounds, while the 40 cal can’t handle the same pressure and size of 10mm rounds. Therefore, it is important to use the correct caliber for your firearm to ensure safety.
