The video opens with joking references to .45 ACP as “God’s caliber,” then quickly sets the stage for a serious comparison of common self-defense calibers in the United States. The hosts explain that the goal is to help viewers decide what they should realistically carry, not to fuel caliber wars. They begin with .22 LR, noting its clear advantages: extremely low recoil, low cost, and ease of shooting. These traits make .22 ideal for brand-new shooters, especially many female clients who may be intimidated by larger calibers. However, they strongly caution against relying on .22 LR for self-defense because it rarely causes immediate incapacitation. A real robbery incident is described where a victim was shot multiple times with .22, including a hit to the middle finger that did not even break bone and a heart shot that led to a slow, agonizing death. This story underscores that while .22 can be lethal, its stopping power is limited and unreliable for quickly stopping a violent threat.
Continuing the rimfire discussion, the hosts briefly highlight .22 Magnum pistols such as the KelTec PMR30 and Taurus TX. These handguns are praised as fun, low-recoil options that are excellent for new shooters to build confidence and refine fundamentals. The PMR30, in particular, is mentioned as a favorite due to its high capacity and very light recoil. From there, the conversation transitions to centerfire defensive calibers, starting with .380 ACP. The presenters describe .380 as a common first concealed carry choice for clients who find 9mm intimidating. They reference popular .380 models like SIG pistols, the Smith & Wesson Bodyguard, Glock 42, and the Smith & Wesson EZ Slide in .380, noting that these guns are compact, easy to rack, and generally user-friendly. This chapter sets up .380 ACP as a bridge between ultra-soft rimfire training guns and more capable defensive calibers, especially for recoil-sensitive or smaller-handed shooters.
The discussion of .380 ACP focuses on how surprisingly shootable many of the very small pistols are. The hosts point out that micro .380s often have better ergonomics than expected, but shooters must be careful not to grip too high and impede the slide, which can cause malfunctions. Ballistically, .380 is described as essentially a shorter, lighter 9mm, typically running around 900–1000 feet per second. While it does not match 9mm performance, it offers decent terminal effect with modern defensive loads. The presenters emphasize that .380’s softer recoil makes it a strong option for new shooters, many women, older individuals, or anyone with hand or strength limitations. It is also recommended for minimal-clothing environments like the gym or beach, where very small guns are easier to conceal. One host notes a personal preference to standardize on 9mm for ammunition consistency, but still acknowledges .380 as a valid, effective choice when recoil or concealment constraints demand it.
Attention then shifts to 9mm, starting with its origins in 1901 with Georg Luger. Over the decades, 9mm evolved into the dominant handgun caliber worldwide, adopted by NATO, the FBI, most U.S. law enforcement agencies, and the U.S. military. The hosts explain that this widespread adoption is driven by 9mm’s balance of terminal performance, capacity, recoil, and weight. Compared to larger calibers, 9mm allows higher-capacity magazines and lighter carry loads, while still delivering strong defensive effectiveness with modern hollow points. Recoil is manageable for most shooters, enabling faster follow-up shots and better shot placement under stress. The Daniel Defense H9 is used as an example of a well-balanced, all-metal 9mm pistol that tracks smoothly and allows quick, accurate strings of fire. The presenters frame 9mm as the current “sweet spot” for everyday carry, combining shootability, availability, and proven real-world results in law enforcement and defensive use.
After establishing 9mm as the preferred caliber, the hosts stress that ammunition choice is just as important as caliber. They recommend using inexpensive ball ammo for practice but insist that defensive carry ammo should come from reputable manufacturers with proven performance. Viewers are encouraged to mirror law enforcement choices, such as FBI-approved loads like Hornady Critical Duty and Critical Defense, or similar offerings like G2. The Walther PDPF is highlighted as a 9mm pistol designed to be more accessible to new and smaller-handed shooters, featuring reduced slide force, a lighter trigger, and a smaller grip circumference. This design helps more people manage 9mm effectively. The presenters warn against flashy, gimmicky ammunition marketed with colored tips or names like “zombie killer,” explaining that such products often lack serious testing. They urge shooters to research ballistic performance and penetration standards rather than buying based on marketing claims or appearance alone.
The conversation moves to .40 S&W, which the hosts describe as essentially a “10mm short,” similar to how .380 is a “9mm short.” They explain that .40 was developed in response to an FBI request in the 1980s for a reduced-recoil alternative to full-power 10mm, which many agents struggled to qualify with. For years, .40 became a dominant law enforcement caliber, with agencies issuing pistols like the Smith & Wesson M&P 40 and Glock 22. However, the hosts note that .40’s noticeably snappier recoil, lower capacity, and higher cost compared to modern 9mm have led to a broad shift back to 9mm starting around 2011–2013. They characterize .40 as increasingly obsolete for most shooters, despite its solid terminal effect. The discussion then turns to .45 ACP, praised for its historical significance and strong terminal performance but criticized for higher recoil, heavier guns, lower capacity, and slower, inherently subsonic bullets that can be less effective through barriers than 9mm.
Expanding on .45 ACP, the hosts compare modern double-stack and classic single-stack platforms. The FNX-45 is described as a well-made, high-capacity .45 that is fun to shoot but very thick and challenging to conceal, especially with tighter clothing. One host notes that it took several shots to get comfortable with the recoil, reinforcing that .45 requires more effort to manage than 9mm for many shooters. In contrast, traditional 1911-style pistols, such as the Century Arms Centurion 2, typically offer only 7–8 rounds in a single-stack magazine. While these guns have a storied history in law enforcement and SWAT use and are beloved by enthusiasts, they are heavy, relatively low in capacity, and bulky for concealed carry. The presenters acknowledge .45’s strong fan base and “two world wars” reputation but conclude that its weight, recoil, and capacity tradeoffs make it a less practical everyday carry choice for most modern users compared to 9mm.
The topic shifts to 10mm after a viewer-style question about choosing between 9mm and 10mm for hiking in bear country. The hosts recommend 10mm for this role due to its significantly greater power and penetration. They describe 10mm as a hotter, taller version of .40 caliber, capable of driving heavy bullets at high velocities suitable for defense against bears, mountain lions, and other large animals. Historically, the FBI adopted 10mm in the 1980s but later abandoned it because many agents struggled with the heavy recoil and had difficulty qualifying, which led to the development of .40 S&W. Despite that, the hosts emphasize that 10mm remains an excellent choice as a hunting or hiking sidearm. They mention personal use of a Springfield XDM Elite 10mm and reference other 10mm pistols like the Glock 40, noting that while recoil is stout, it is manageable in full-size platforms and offers a substantial performance margin over 9mm in wilderness scenarios.
In the final chapter, the hosts focus on the FN 510, describing it as the softest-recoiling 10mm handgun they have used. They characterize its recoil as feeling somewhere between 9mm and .40, and noticeably more controllable than the Springfield XDM Elite and SIG XTen in 10mm. The FN 510 is recommended as a strong option for hiking, camping, and home-defense or nightstand use, where its size, weight, and capacity are advantages rather than drawbacks. However, they caution that its chunky grip and overall bulk make it less ideal for concealed everyday carry compared to a compact 9mm. The presenters conclude that for roughly 90 percent of people, a 9mm handgun loaded with reputable defensive ammunition is the best all-around choice. They stress that any reliable gun and caliber a person already owns and can handle is better than being unarmed, and they emphasize that consistent training and practice with one’s chosen firearm matter more than chasing the “perfect” caliber.
