Exploring Popular Pistol Caliber Carbine (PCC) Calibers: Muzzle Velocities, Energy on Impact, and Use Cases

If you’re a PCC fan or thinking about diving into the world of pistol-caliber carbines, you already know there’s something special about them. They’re nimble, versatile, and let you punch paper, ping steel, or even defend your home with ease and style. But with so many calibers out there, how do you pick the perfect one? Let’s turn up the fun and take a look at some of the most popular PCC calibers, ranked by velocity, power, and purpose!

1. 9mm Luger: The "Everyday Hero"

• Muzzle Velocity: 1,200 - 1,600 fps (pretty zippy!)
• Energy on Impact: 350 - 600 ft-lbs (not bad for the lightweight champ)

The 9mm is the go-to, all-around favorite for PCCs. Why? Because it’s a little like your favorite hoodie – reliable, comfortable, and fits just about any occasion. Low recoil? Check. Affordable? Check. Powerful enough for self-defense but light enough for competition? Double-check. PCC barrels make the 9mm faster and pack a bit more punch than a handgun – a winning combo for any range day!

Perfect For: First-timers, range rats, and anyone who loves ringing steel all day.

2. .45 ACP: The "Slow & Steady Slugger"

• Muzzle Velocity: 850 - 1,100 fps (low and slow)
• Energy on Impact: 400 - 500 ft-lbs (packs a wallop up close)

The .45 ACP brings big energy, like the friendly giant of the PCC calibers. It's all about delivering impact at a leisurely pace, making it ideal if you want some serious stopping power without the super speed. Perfect for when you want your hits to feel extra heavy but still easy to control.

Perfect For: Big-bore lovers, classic cartridge fans, and close-range powerhouse seekers.

3. .40 S&W: The "Middleweight Contender"

• Muzzle Velocity: 1,200 - 1,500 fps (a nice sweet spot)
• Energy on Impact: 450 - 650 ft-lbs (packs a punch)

The .40 S&W is like the 9mm’s big sibling who’s always pushing a little harder. Known as the “tweener” caliber, it offers more oomph than the 9mm but without the heft of the .45. In a PCC, the .40 gets a boost in speed, making it a powerful choice for shooters looking for a little extra something in their PCC performance.

Perfect For: Those looking for a well-rounded power boost in their PCC without going full beast mode.

4. 10mm Auto: The "Bigfoot Buster"

• Muzzle Velocity: 1,400 - 1,700 fps (fast and ferocious)
• Energy on Impact: 600 - 800 ft-lbs (hits like a truck)

The 10mm Auto is the PCC’s answer to “Why not?” This caliber can take on medium game and hit steel hard, all while looking impressive in your ammo box. Recoil is a bit more noticeable, but if you’re up for a bit of a ride, the 10mm will deliver in spades.

Perfect For: Adventurers, hunters, and anyone who wants to feel a little extra awesome with every shot.

5. .357 SIG: The "Speed Demon"

• Muzzle Velocity: 1,300 - 1,700 fps (zoom zoom)
• Energy on Impact: 500 - 700 ft-lbs (impact city)

The .357 SIG has a need for speed! It’s designed to mimic the high-velocity punch of a .357 Magnum in a semi-auto format. With flat shooting characteristics and higher-than-average energy, this caliber zips through the air, providing a great balance of speed and power in PCC platforms.

Perfect For: Fast-action lovers, those looking for flat trajectories, and folks who like their PCC with a bit of a kick.

6. .357 Magnum: The "Range Cowboy"

• Muzzle Velocity: 1,400 - 1,800 fps (yee-haw speed)
• Energy on Impact: 600 - 800 ft-lbs (wild west power)

Though usually found in lever-action carbines, the .357 Magnum is a classic performer in PCCs, delivering that sweet revolver nostalgia with every pull. In a longer barrel, this powerhouse caliber gains extra speed and energy, making it a great choice for both target shooting and small game hunting.

Perfect For: Those who want a hint of the Old West, hunters, and folks with a soft spot for a legendary caliber.

7. 5.7x28mm: The "Sci-Fi Shooter"

• Muzzle Velocity: 1,700 - 2,100 fps (faster than fast!)
• Energy on Impact: 300 - 400 ft-lbs (light but lightning quick)

The 5.7x28mm is the new kid on the block and might just be the most futuristic-looking round on this list. Originally designed for the FN P90, it’s light, fast, and low-recoil, so you can squeeze off shots without feeling the usual jolt. While its impact energy is on the lower side, the flat trajectory makes it a ton of fun in a PCC.

Perfect For: Competition shooters, sci-fi fans, and anyone who wants to feel like they’re in the future.
