FBI Special Agent Ray Cook told The Washington Post that "the lighter the bullet, the faster the gun can 'drive' the round into the target. For the FBI, that translates into 12 to 18 inches of penetration into the human body. "
Pistols chambered for the 9mm have less recoil and are generally easier to shoot, even smaller backup models like the Springfield Armory XD-S 9mm.
More 9mm pistols on the market means more options for officers. The Heckler & Koch P30 is just one that is designed to fit a wide variety of users.
There are too many 9mm loadings to count, but it doesn’t take much effort to find the right load for the job. Hornady’s Critical Duty loads are designed for optimum penetration through things like heavy clothing.
Typically, 9mm ammunition is cheaper than other offerings, so officers can get more training time in with less money.
9mms are known for being reliable, even in short-barreled platforms like Springfield Armory’s EMP 1911.
Many 9mm pistols, like the Glock 19 Gen4, are known for being extremely reliable and have long service lives.
Paul Buffoni (Affiliation: Bravo Company USA, Inc.; former USMC service; Position: Founder and CEO) 9mm or .45 ACP? 9mm. Reason: Additional capacity of 9mm pistols is a great benefit. Current 9mm ammunition ballistics will do the job, if I do mine.
John Chapman (Chappy) (Affiliation: LMS Defense / EAG Tactical;
Position: Weapons and Tactics Instructor) 9mm or .45 ACP? 9mm. Reason: I prefer the 9mm, because it is plentiful, cheaper to shoot, easier to make rapid follow-up shots with and is lethal enough when the shooter places the rounds in the proper place in the target. Having said that, the .45 ACP is a great round as well, and is slightly superior to the 9mm when engaging targets inside of vehicles. I use both calibers in my work and training pursuits, depending on the mission.
Chris Cheng (Affiliation: History Channel’s Top Shot Season 4 Champion; Bass Pro Shops and Leupold & Stevens Pro Staffer; Shoot to Win, Author;
Position: Top Shots winner; author) 9mm or .45 ACP? 9mm. Reason: 9mm: More affordable.
Chris Costa (Affiliation: Costa Ludus; Position: Founder) 9mm or .45 ACP? 9mm. Reason: Both the 9mm and .45 are great calibers for everyday carry, and both offer very good terminal ballistics for stopping power. When considering everyday carry, round count capacity is very important for several reasons: multiple threats, vehicle windshields and concentrated fire on vehicles or cover in order to achieve penetration of a specific location, and suppress to cover if it’s a viable tactic or option. While I own expensive .45s, 99 percent of the time my typical everyday carry is a Salient Glock in 9mm with a spare magazine. There are no magic bullets, so shot placement and accuracy under speed based on your sight package is paramount to your safety as well as the safety of others around you. Bring enough gun to the fight, but bring one you can handle.
Dave Emary (Affiliation: Hornady Manufacturing;
Position: Senior Scientist) 9mm or .45 ACP? 9mm. Reason: Current 9mm ammunition has more consistent and better barrier penetration than .45 ACP. The .45 ACP is probably a bit better in terms of a larger wound cavity if no barrier is involved. If a barrier is involved, a 9mm +P load is superior. You can carry a lot more 9mm rounds in the mag, and it is easier to shoot well.
Ken Hackathorn (Affiliation: Alias Training & Security Services; Position: Former U.S. Army Special Forces Small Arms Instructor; Gunsite Instructor (retired); NRA Police Firearms Instructor (ret.); FBI Certified Firearms Instructor (ret.); Certified Deputy Sheriff (ret.)) 9mm or .45? Both. Reason: Imagine you’re in a room with one door, five Jihadists armed with dull knives are going to come through the door one at a time every 60 seconds with the goal of cutting your head off. You have the choice of one of two identical handguns, one in 9x19mm and the other in
.45 ACP. Both have only five rounds of ball ammo. Which one would you pick? I carry a
.45 ACP daily, but practice and train with 9x19mm pistols.
Jordan Hunter (Affiliation: Formerly of Daniel Defense; retired USMC Infantry; Position: Formerly Director of Marketing/Communications, Daniel Defense)
9mm or .45 ACP? 9mm. Reason: In the context of concealed carry for personal protection, my priorities are speed and accuracy, lethality and magazine capacity, so I go with the 9mm without hesitancy. Speed and accuracy are both related to follow-up shots, which are generally more manageable in 9mm. Any question of the 9mm’s lethality, or stopping power, has been put to rest with the relatively recent technological advancements in self-defense 9mm ammo. Lastly, I can carry more rounds in a compact pistol’s magazine if it’s chambered in 9mm versus what a compact .45 allows.
Erik Lund (Affiliation: Lund Performance & Consulting; Instructor for Shooting-Performance.com;
FNH-USA Pro Shooting Team; Law Enforcement;
Position: Owner; Instructor; Professional Shooter) 9mm or .45 ACP? Both. Reason: More so than any other pistol caliber, the 9mm has been the largest benefactor of handgun bullet design and technology and is a proven performer in the real world. Although the recoil and performance of the .45 requires more skill and practice to effectively employ, it does make big bigger holes. And bigger holes bleed faster.
Frank Proctor (Affiliation: Way of the Gun Performance Shooting; Position: Owner & Instructor) 9mm or .45 ACP? 9mm. Reason: All of my pistols are 9mm. When I consider things like magazine capacity, recoil management, size of the gun, cost of training and the advancements in ammunition technology, it’s an easy choice. I carried a 9mm pistol in Afghanistan and Iraq because that’s what I was issued as a U.S. Army Special Forces Soldier. I carry one everyday now because it’s what I believe in for the reasons listed above. I carry Hornady 135 grain Critical Duty in mine and have seen it outperform .40 and .45 duty ammo in the FBI protocol.
JJ Racaza (Affiliation: Nevada Arms LLC;
Position: Co-Owner & Competition Shooter) 9mm or .45 ACP? 9mm.
Reason: 9mm wins my vote on this one. Simple fact that the technology around projectiles has made a smaller caliber even more effective in the real world: better recoil, better penetration and similar stopping power.
Nate Stokes (Affiliation: Unity Tactical Inc.;
Position: Co-Owner; Police Officer) 9mm or .45 ACP? 9mm. Reason: I shoot 9mm because cartridges in gun equal time in fight. High capacity helps me mitigate the in-fight mag change.
Rachel VandeVoort (Affiliation: Kimber Mfg., Inc.; Position: Marketing / Product Manager) 9mm or .45 ACP? 9mm. Reason: 9mm is a bit of a superhero in my book. Thanks largely to advancements in ammunition, it is a caliber that is the epitome of versatility by lending power and ease of handling to most any firearm; characteristics highly valued when bringing new gun owners into the mix or encouraging growth in smaller-caliber shooters. It can be the segue caliber that builds confidence to explore other/new firearm platforms or more powerful calibers not otherwise considered. In my mind those are super powers.
Larry Vickers (Affiliation: Firearms Industry consultant; Position: Shooting instructor & TV show host) 9mm or .45 ACP? 9mm (with an *). Reason: To me this is an easy choice. If you can carry one of the modern 9mm hollow points, then this caliber is the choice. Well-designed 9mm hollow point ammo has a very good track record in real-world shootings when you establish effective hits on target. If hollow points are not an option, then I would opt for .45 ACP—at that point poking a bigger hole in the bad guy is better than a smaller hole. Like I said, easy choice.
Bill Wilson (Affiliation: Wilson Combat; Position: Founder/President)
9mm or .45 ACP? 9mm. Reason: For most of my shooting career I’ve been a .45 guy, but have recently favored 9mm because of factors such as lower ammunition cost, less recoil, higher ammunition capacity and improved performance of 9mm ammunition due to advanced propellants and bullets.
9mm Wins: The Round Table Has Spoken! Are you surprised that it ended up being a landslide from those who decided in favor of 9mm? We certainly were. It looks like 9mm has really surpassed .45 ACP as the preferred round – well, at least with our Round Table panelists that is.

Ammo Change: FBI Switching Back To 9mm Rounds
More recently, the Federal Bureau of Investigation announced that it would be switching back to the 9mm round.
The FBI used the round until a 1980s shootout with a suspect that left two agents dead. The Bureau cited penetration as a major problem with the round, but current technology has the FBI thinking otherwise.
