Keltec Pr57 5 7X28Mm20 Rounds Tan
About this product
The KelTec PR57 is a compact pistol chambered in 5.7x28mm, the fast, flat-shooting round FN originally developed for its P90/Five-seveN platform and now built by several other manufacturers, including KelTec. It's finished in tan and built around KelTec's typically compact, polymer-heavy design philosophy — small, light guns chambered in cartridges that usually come in bigger packages. The 5.7x28mm round itself is known for very light recoil and higher magazine capacity relative to its size, which is the main reason shooters look at guns like this one.
What is 5.7x28mm good for?
Light recoil and fast, flat-shooting follow-up shots are the round's calling card, which makes it well suited to plinking, range training, and home defense with the right ammunition. It's not a hunting cartridge, and it's not meant to compete with 9mm or .45 ACP for raw stopping power per shot. Shooters pick it specifically for how easy it is to shoot quickly and accurately.
What magazine capacity actually ships to California?
10 rounds — California caps magazine capacity at 10 rounds statewide, so any factory 20-round magazine referenced for this pistol is not what leaves the counter on a California order. Orders shipping to CA get a compliant 10-round magazine instead. See California gun laws for the full rundown on capacity and transfer rules.
How does 5.7x28mm compare to 9mm?
It kicks noticeably less than 9mm and shoots flatter at typical handgun ranges, but the projectile is lighter and ammunition is less common and pricier per round. Terminal performance depends heavily on the specific load, and steel-core variants of the cartridge are restricted in some jurisdictions. It's a different tool than 9mm, not a straight upgrade or downgrade.
Who is this not for?
Anyone who wants a common, cheap-to-shoot caliber should stick with 9mm — 5.7x28mm ammo is harder to find and costs more per round. It's also not a hunting round, so buyers looking for a field gun for game should look elsewhere.
What color does it come in?
Tan, as listed. Check with the dealer if other finish options are available for this model.
Does it work in California?
Yes, through the standard process — licensed CA FFL, DROS background check, 10-day wait, and roster confirmation for the specific configuration — but only with the compliant 10-round magazine noted above, not the higher-capacity factory version.

Frequently asked questions
- Can I get the 20-round factory magazine in California?
- No — California caps magazine capacity at 10 rounds statewide, so CA orders ship with a compliant 10-round magazine instead of the higher-capacity version.
- Is 5.7x28mm hard to find ammo for?
- It's more specialized than 9mm — expect fewer brands on the shelf and a higher per-round cost, though availability has improved as more 5.7 pistols have hit the market.
- Does it kick a lot?
- No — 5.7x28mm is known for notably light, flat recoil compared to typical defensive pistol calibers, which is a big part of its appeal.
- What color does this come in?
- Tan, as listed — check with the dealer if other finishes are available.
- Is this good for home defense?
- With modern defensive-grade 5.7x28mm ammunition, yes; steer clear of FMJ-only loads for that role, the same rule that applies to any defensive pistol.
