We offer 5.7x28mm ammunition compatible with several popular civilian firearms designed around this high-velocity cartridge. These platforms take full advantage of its low recoil, flat trajectory, and high magazine capacity.

• The FN Five-seveN pistol remains the original and most recognized platform, featuring a 20-round magazine and excellent ergonomics for self-defense or range use.
• The Ruger-57 pistol provides an affordable, reliable alternative with a similar 20-round capacity, polymer frame, and adjustable sights for precise shooting.
• The FN PS90 carbine (civilian-legal version) delivers significantly higher velocity from its 16-inch barrel, making it ideal for home defense or varmint control with a 30- or 50-round top-mounted magazine.
• The CMMG Banshee pistol or carbine in 5.7x28mm offers AR-style handling with compact configurations and compatibility with standard AR accessories.
• The PSA 5.7x28mm Rock pistol and other budget-friendly clones provide accessible entry points while maintaining reliable function with factory loads.
• Aftermarket conversions and dedicated firearms from smaller manufacturers increasingly support this caliber for versatile personal protection setups.

We consider 5.7x28mm an effective and practical choice for self-defense due to its unique ballistic performance and user-friendly handling characteristics.

• High muzzle velocity (often 1,800–2,200 fps from pistols) creates rapid energy transfer and excellent barrier penetration when needed.
• Low recoil allows faster, more accurate follow-up shots under stress compared to many traditional handgun calibers.
• Reduced overpenetration risk in many civilian loads helps minimize danger to bystanders or property behind the target.
• High magazine capacity (20+ rounds in most compatible pistols) provides ample rounds before reloading in defensive scenarios.
• Lightweight bullets and flat trajectory improve hit probability at typical self-defense distances (7–25 yards).
• Controlled expansion in JHP or polymer-tipped loads enhances terminal performance while limiting excessive penetration.

We find that 5.7x28mm delivers noticeably lower recoil than 9mm Luger, making it easier to shoot accurately and quickly for most users.

• The cartridge produces approximately 30% less felt recoil due to its much lighter bullet weights (27–40 grains vs. 115–147 grains in 9mm).
• Lower recoil impulse allows shooters to maintain better sight alignment and trigger control during rapid fire.
• Reduced muzzle flip helps keep the firearm on target, especially beneficial for smaller-statured or less experienced shooters.
• Faster recovery time between shots improves practical shooting speed in defensive or competitive situations.
• The straight-back recoil impulse feels smoother compared to the snappier push of 9mm in similar-sized pistols.
• Overall, the lower recoil contributes to higher round counts during training without fatigue.

We stock a variety of civilian-legal 5.7x28mm bullet types tailored to different shooting purposes, from range practice to defensive and varmint applications.

• Full Metal Jacket (FMJ) loads provide reliable feeding, consistent accuracy, and cost-effective performance for target shooting and plinking.
• V-MAX polymer-tipped bullets offer rapid expansion and high fragmentation, making them excellent for varmint control and precise target work.
• Jacketed Hollow Point (JHP) variants, such as SS195LF, deliver controlled expansion with lead-free construction suitable for self-defense or indoor ranges.
• Lead-free options using aluminum or copper cores meet range restrictions while maintaining ballistic performance close to standard loads.
• Sporting rounds with blue polymer tips (often marketed for training) combine affordability with reliable cycling in most firearms.
• Heavier 40-grain FMJ or tipped projectiles provide slightly better penetration and energy retention at longer distances.

We recommend 5.7x28mm as a capable and fun option for varmint hunting, particularly with the right loads and platforms.

• Polymer-tipped V-MAX or similar expanding bullets deliver rapid fragmentation and devastating terminal effect on small game like prairie dogs, ground squirrels, or coyotes at moderate ranges.
• High velocity (up to 2,800 fps from carbines) creates flat trajectories that simplify holdover and improve hit probability out to 150–200 yards.
• Low recoil and minimal muzzle blast allow quick follow-up shots when engaging multiple targets or moving varmints.
• The cartridge’s accuracy shines in longer-barreled rifles or carbines, making precise headshots easier on small targets.
• Reduced overpenetration compared to traditional rifle rounds helps limit damage to surrounding areas during field use.
• Lightweight ammunition allows carrying more rounds in the field without added weight burden.

We observe significant velocity gains with longer barrels in 5.7x28mm firearms, which directly improves downrange energy, trajectory flatness, and terminal effectiveness compared to shorter pistol barrels.

• Pistol barrels (typically 4–5 inches) produce muzzle velocities around 1,600–2,000 fps, delivering solid performance for self-defense and close-range target shooting.
• Carbine or PDW barrels (10–16 inches, such as the FN PS90) push velocities to 2,300–2,800 fps or higher, increasing energy transfer and extending effective range.
• Each additional inch of barrel length typically adds 30–50 fps or more, depending on the specific load and powder charge.
• Higher velocities from longer barrels flatten the trajectory, reducing holdover and making hits easier at 50–200 yards.
• Increased muzzle energy (often 350–450+ ft-lbs from carbines) enhances terminal ballistics on varmints or defensive targets.
• The cartridge’s design shines in longer barrels, where it achieves near-rifle-like performance while maintaining very low recoil.
• Suppressors pair especially well with longer barrels, as the added velocity helps maintain subsonic or near-subsonic loads for quieter operation.

We confirm that 5.7x28mm has official NATO standardization, which supports its growing adoption for military, law enforcement, and civilian applications worldwide.

• In 2021, NATO formally adopted the 5.7x28mm as STANAG 4509 for use in personal defense weapons and submachine guns.
• The standardization covers both the original SS190 penetrator round and compatible civilian/sporting variants.
• This NATO recognition ensures consistent specifications for case dimensions, primer type, and pressure limits across manufacturers.
• It promotes interoperability among allied forces using platforms like the FN P90 and Five-seveN derivatives.
• Civilian ammunition adheres to the same basic cartridge geometry, allowing reliable function in standardized firearms.
• The STANAG designation has increased availability and trust in the cartridge for non-restricted use.
• Standardization helps maintain quality control and ballistic consistency for all approved loads.

We attribute the exceptionally flat trajectory of 5.7x28mm to its combination of high muzzle velocity and lightweight bullets, which minimizes bullet drop over distance.

• Muzzle velocities often exceed 2,000 fps from pistols and reach 2,500–2,800 fps from carbines, keeping the bullet supersonic much farther than most handgun rounds.
• Lightweight projectiles (27–40 grains) experience less gravitational drop compared to heavier bullets in traditional calibers like 9mm or .45 ACP.
• High ballistic coefficients in many loads (especially polymer-tipped V-MAX) help retain velocity and resist wind drift.
• The flat-shooting nature reduces the need for significant holdover at practical ranges of 25–150 yards.
• Compared to 9mm (which drops noticeably beyond 50 yards), 5.7x28mm maintains point-of-aim/point-of-impact alignment farther out.
• This trajectory advantage makes the cartridge easier to use for precise shots in defensive, varmint, or competitive scenarios.
• The combination delivers rifle-like flatness from compact platforms without the added recoil or weight.

We provide several lead-free 5.7x28mm options that meet environmental and range regulations while delivering performance comparable to standard loads.

• SS195LF uses a lead-free aluminum-core bullet with a blue polymer tip, offering excellent expansion and reduced barrel fouling.
• These loads feature lead-free primers to eliminate heavy metals entirely, making them ideal for indoor shooting ranges with strict rules.
• Ballistic performance remains close to conventional rounds, with muzzle velocities around 1,800–2,100 fps from pistols.
• Lead-free variants maintain reliable feeding and extraction in FN Five-seveN, Ruger-57, and PS90 platforms.
• They provide effective terminal ballistics for self-defense or varmint use without environmental concerns.
• Many ranges that restrict lead-core ammunition specifically allow or prefer these cleaner-burning alternatives.
• Availability of lead-free 5.7x28mm supports continued civilian use in restricted facilities and eco-conscious shooting.

We position 5.7x28mm as one of the leading PDW cartridges due to its balance of velocity, capacity, recoil, and versatility compared to alternatives like 4.6x30mm or 9mm.

• It achieves higher muzzle velocity (2,000+ fps from pistols) than 4.6x30mm, resulting in better energy delivery and flatter trajectory.
• Magazine capacities remain high (20–50 rounds) due to the slim, bottlenecked case design, similar to or exceeding competitors.
• Recoil stays extremely low, allowing faster and more controllable follow-up shots than most centerfire handgun rounds.
• Civilian availability far exceeds restricted military-only options like 4.6x30mm, making 5.7x28mm more accessible for range and defense use.
• It offers better barrier penetration in certain loads while maintaining lower overpenetration risk than traditional rifle rounds.
• Compatibility with both pistols and carbines provides greater platform flexibility than some dedicated PDW calibers.
• Overall ballistic efficiency and growing aftermarket support make 5.7x28mm a practical, high-performance choice in its class.

We find 5.7x28mm to be an outstanding cartridge for target shooting thanks to its low recoil, high accuracy potential, and economical high-volume practice capability.

• Flat trajectory and high muzzle velocity reduce the need for holdover adjustments, making it easier to hit targets consistently at 25–100 yards.
• Lightweight bullets and minimal muzzle rise enable faster follow-up shots and tighter groups during rapid-fire drills.
• High magazine capacity (20+ rounds in pistols, 30–50 in carbines) supports extended range sessions with fewer reloads.
• Excellent inherent accuracy from most factory loads delivers sub-MOA potential in carbines and consistent performance in pistols.
• Affordable civilian FMJ and training loads make high-volume practice cost-effective compared to many centerfire rifle cartridges.
• The cartridge’s smooth shooting characteristics build confidence and improve overall marksmanship skills over time.

We note that 5.7x28mm provides controlled and consistent penetration in soft tissue, typically in the FBI-recommended 12–18 inch range for defensive loads while minimizing excessive overpenetration.

• Most civilian JHP and polymer-tipped loads achieve 11–13.5 inches of penetration in ballistic gelatin tests.
• Lighter, faster bullets (27–40 grains) tend to yaw or fragment after impact, helping limit penetration depth compared to non-expanding rounds.
• Reduced overpenetration risk makes it suitable for home defense scenarios where bystanders or walls are behind the target.
• Heavier 40-grain FMJ loads can reach 14–16 inches, offering reliable penetration through clothing or light barriers when needed.
• Expansion in defensive variants (such as SS195LF) increases wound channel size while still staying within safe penetration limits.
• Ballistic performance remains consistent across common barrel lengths, providing predictable results for self-defense planning.
• The cartridge’s design balances penetration and energy transfer effectively for real-world defensive use.
