DO NOT DO THIS!!!!!!!!!!!!!!!!!!!!
40
No
the 40 cal is a little bigger then the 357
Yes, a 45 caliber bullet is bigger than a 40 caliber bullet. A .45 is0.45 inches wide in diameter and a .40 is 0.4 inches in diameter.
A 40mm handgun would fire a bullet the size of a golf ball. No such critter. There IS a .40 caliber handgun (about 10mm). There are dozens of larger caliber handguns than .40 caliber. They include the .41, .44. .45, .455. .460, .475, .500- and several others.
Either platform can be larger than the other. The 45 has the larger projectile. Caliber is defined as the diameter in fractions of an inch, so .40 caliber is smaller in diameter than .45 caliber. Caliber can also be defined in the metric system, measured in milimeters. The .40 caliber cartridge is equivalent to 10mm in diameter. As noted, the size of a handgun can vary widely within one caliber, so it is perfectly reasonable to have a smaller handgun crafted in a larger caliber.
The .40 is larger in diameter and (normally) has a heavier bullet.
No. The length of the 10mm cartridge is necessary to achieve the proper headspace in a 10mm pistol. While a .40 cartridge would probably chamber, firing this round in a 10mm pistol is extremely dangerous, and can lead to damage to the weapon, as well as injury to the operator.
It's not safe to do. You won't get proper headspacing (the 10mm casing is significantly longer), and the end result could be disastrous.
A glock 45 is a .45 caliber pistol, which fires a 45 caliber round. The glock 10mm fires 10mm rounds, which are .3945 caliber. Which is slightly smaller than the .40 caliber. Both of the two calibers, .45 and 10mm, are the 2 mosst expensive caliber weapons of glock. A 10mm is used mainly for law enforcement. You can fire rapidly with a Glock 10mm and be more accurate than you would with a Glock .45 caliber simply because the glock 10mm will have less recoil than the Glock .45 will. The Glock .45 will most likely do more damage though. Please Correct Me If I Am Wrong. Thanks, Bronson.
45 has the larger projectile. Size of the handgun will vary.
