PAPA PEG IS CORRECT, EVERY FIREARM HAS A MUZZLE VELOCITY BUT THIS VARIES DUE TO THE AMOUNT OF POWER (POWDER) USED IN THE SHELL AND OTHER VARIANTS, CALIBRE.TWIST IS RIFLING ETC. HAVING SAID THAT MOST MUZZLE VELOCITIES ARE IN THE 2000 PLUS FEET PER SECOND.

Different handguns have different muzzle speeds

A bullets shot out of a handgun has its greatest velocity just when leaving the muzzle. All slow down from there. Another consideration if you have 2 identical guns shooting the exact ammo but one has a six inch barrel and the other a 4 in. The longer the barrel will have the higher terminal velocity, all other things being equal. Velocity of any bullet is measured in fps, feet per second. It also depends on the size of the projectile of same caliber bullets and type of powder used. For our comparison we are compare Remington UMC_Pistol Ammo maintaining the same gun powder make-up. Keep in mind that larger caliber ammo has a larger casing were more powder can fit inside but has a heavier, measured in grains or gr for short, projections to propel.
We will use the 3 most popular large caliber ammo with various sized bullets made for each caliber.
9mm 115 grain (gr) bullet> 1145fps - 9mm 124gr bullet> 1100fps -9mm 147gr bullet> 990fps - 40s&w 165gr bullet> 1150fps - 40S&W 180gr bullet 1015fps - 45acp 185gr bullet>1015fps - 45acp 230gr bullet> 835fps. Most large size caliber pistols like were just compared have an average of just around 1050fps at muzzle velocity. How about a thumbs up for that accurate research!
