The KelTec PR-5.7 with RFX11 optic in black is a 5.7x28mm pistol built around KelTec’s rotary barrel and top-loading design (KelTec part no. PR57BLKOPTIC). Twenty rounds fit in the grip, and this version is listed with an RFX11 optic so the pistol is ready for a dot sight from the start. KelTec says the rotary barrel makes the PR-5.7 nearly 40 percent lighter than the next lightest 5.7mm pistol on the market. The slim, magazine-less frame suits concealed carry and range use with a small-bore, flat-shooting cartridge. It is a compact way to get into the 5.7x28mm platform.

Key Specifications

• The chambering is 5.7x28mm, a small, high-velocity cartridge known for flat trajectory and light recoil.
• Capacity is 20+1, with the rounds held in the grip rather than a removable magazine, which keeps the frame slim.
• Barrel length is 4.00 inches, a rotary barrel that keeps the pistol short and light for carry.
• Unloaded weight is 13.86 ounces, light enough to carry all day without noticing it.
• The pistol is listed with an RFX11 optic in the black version, so a sight is part of this SKU.
