Gear Review: Speed Ledge
The key to running a handgun in shooting competitions is the ability to quickly get back on target after making your shot. Hitting the first target is easy, but it’s all about how quickly you can take down the next ones. The ability to make quick follow-up shots comes only after hundreds of hours of practice on the range, or thanks to winning the genetic lottery like a Lena Miculek. A few companies have been developing some products to try and make it easier to control the recoil of a firearm and get it back on target quicker, and one of those companies has come out with a device known as the Speed Ledge.
The idea is simple. The device attaches to the front of the gun, and has a small serrated pedal you use to rest your support thumb. It gives you the ability to exercise more control over the muzzle by applying force directly to that part of the gun. The concept has been tried many times before, and is a staple in the “race gun” sections of handgun shooting (known as a “gas pedal” or “go pedal”), but those devices have always been attached to the back of the firearm and typically are dependent on using the grip panels to hold it in place. The Speed Ledge bypasses that whole headache by clamping directly onto the forward Picatinny rail.
