Very similar. The 40 is slightly larger and heavier, but compensates with more stopping power. I have found both equally accurate. Given a choice, I'd take the 40 cal for use in actual practice, but would use the 9mm for the range and target shooting.
It depends on what you want to compare. The pistols themselves may or may not be different, it just depends on which two specific brands/models you are comparing. If you are referring to the 10mm cartridge vs. the .40SW, the .40 is shorter and has much less muzzle velocity and energy than a 10mm. The piece of lead however, is the same, normally ranging from 135 grains to 180 grains, although some are 200 grains.
No, no, no. Do not attempt to do this.
9mm is cheeper cause it's a smaller round.
400 mm = 40 cm
Yes, 4000 mm is bigger than 40 cm. To compare the two measurements, you need to convert them to the same unit. Since 1 cm is equal to 10 mm, 40 cm is equal to 400 mm. Therefore, 4000 mm is greater than 400 mm, making 4000 mm bigger than 40 cm.
The last I heard, it was Glock pistols in 9 MM. I think it is a Glock 19.
the best brand of 9 mm that the police use is the glock
3/4 of an inch is 19 mm.
40 mm = 1.575 inches 40 mm = 4 cm
compare it with cm .....mm x 10 cm
40 millimeters = 1.57 inches.Direct Conversion Formula 40 mm*1 in25.4 mm=1.57480315 in
40 mm = 4 cm
