The 9mm represents the smallest cartridge suitable for a duty pistol - it is adequate. The bottom line? Shot placement trumps all - a 9mm bullet hitting center-mass is more effective than a. History teaches us that those people with the most lead/zinc/copper/tin tend to take all the gold and silver they desire. I consider lead, zinc, copper, and tin to historically be the most precious metals (the base metals needed to manufacture weapons ranging from bronze-age swords to modern firearms ammunition). The less metal you use to make a cartridge, the less it will cost. 9mm ammunition costs less, allowing us to shoot more. 40, I seriously doubt two additional rounds of 9mm will make much difference - reload!Ĥ. If you can’t solve a street shooting problem with 16 rounds of. You have 16 rounds with the model 22 (.40 S&W) in the same size package. The 9mm pistols have a higher capacity, so pack more rounds for the fight.Īgain, assuming you’re using Glock pistols, a fully loaded Model 17 (9mm) equals 18 rounds. 45 effectively, why not carry the most power available.ģ. Are you listening Glock? For those who can handle a. If we ever see a modern striker-fired pistol with a single-stack magazine, small officers will have the most tractable sidearm possible, allowing any caliber to fit their hand. 45 caliber single-stack pistol like a champ. I’ve seen some damn small shooters handle a. A smaller grip frame would help marginal performers more than lighter recoil. Would the lower recoil of a 9mm make the difference between passing and failing with some trainees? Maybe. Like other aspects of a program skewed in favor of big guys, she mentally decided to succeed - and did. She wasn’t top-gun in her class - and needed remedial training to pass - but pass she did. Her hand was almost completely around the right side of the pistol for her finger to reach the trigger. I recently saw a small-statured female go through basic police training with a Glock 22. Shooting - including the recoil factor - is primarily a mental exercise, not physical. Less recoil makes the 9mm easier to shoot, especially for “small statured” officers. When I need a small pistol for concealment, a 9mm with high-tech ammo will do.Ģ. 45 for social work or a full-power 10mm in the boondocks. I will always carry the largest drill I can, so my choice for open/duty carry is either a. Check out the chart below, and click on it if you would like to see a larger version. The volume of the permanent cavity calculated from expanded diameter and depth of penetration. Is the bigger hole worth the added recoil? I’ll use the velocity values from Black Hills Ammunition’s line of Barnes Tac-XP bullets in the chart because I have the correlating gelatin expansion/penetration data. Let’s compare the three most common police sidearm cartridges in the most common sidearm. Police bullets commonly need to defeat automobile glass and this is a simple matter of mass the bigger bullets will always do more damage to the target after being shredded by the glass. 45 design, but falls just as far behind when you compare apples to apples. 45 caliber TAC-XPs give proportionately better expansion/penetration than older designs in those calibers.Ī “new” 9mm design might equal the performance of an older. Indeed, modern 9mm projectiles - like bonded designs or the all-copper Barnes TAC-Xp hollow points - do deliver much more reliable expansion and penetration characteristics than older designs.īut. The “high-tech 9mm bullets” argument only holds water if you pretend the improved bullet technologies haven’t been applied to all other pistol calibers. Modern bullet technology has made the 9mm as effective as bigger calibers.
