What are the key features of this used Remington R51?
This Remington R51 9mm 7-round used trade-in pistol brings a few points of interest to the table, especially for those who appreciate a different approach to pistol design. First off, the Pedersen-style delayed blowback action is not something you see every day. It’s designed to reduce felt recoil, making it a potentially softer shooter than some other compact 9mms on the market. From handling a few of these, you can tell Remington was aiming for a comfortable shooting experience.
The grip angle is another notable feature. It’s designed to point naturally, which can help with quick target acquisition. It feels good in the hand, especially for a compact. The slim profile is also a plus for concealed carry, something many folks in Kansas look for. It’s a single-stack design, which contributes to that narrow frame, even if it means a lower capacity compared to some double-stack options.
Being a used trade-in, this particular R51 has seen some use, but it’s been inspected to ensure it’s in good working order. Expect some cosmetic wear, but mechanically, it’s solid. It comes with one 7-round magazine, which is standard for this model. For someone looking for a compact 9mm with a unique operating system and a comfortable grip, this R51 offers a distinct option.
Who is the Remington R51 9mm for?
Buy it if:
- ✅ You’re looking for a compact 9mm pistol for concealed carry with a slim profile.
