KT SP Plate Drop Leg

(The Original Modular Holster Adapter, KT 2015)

sample

Compatible holster models:

Low but high speed drop leg:

The KT SP Plate Drop Leg Bracket gives your holster a lower ride height. The lower ride height is enough to clear Jackets, LBE’s, or Armor Plate Carriers for an easier draw with minimal interference, while not too low to hinder your movement.

The KT SP Plate is available with a straight drop, or with an offset. The offset allows the use of level 2 retention holsters. You can also order the KT SP Plate with or without a thigh strap. The KT SP Plate is made of a semi-rigid thick thermoplastic that can be modified or drilled to allow for more attachment options. The KT SP Plate has thigh strap loops built in and comes pre-drilled with the KT Universal Bolt pattern.

The KT Universal Bolt Pattern will allow you to use Blackhawk, Blade-Tech, G-Code RTI 39, and Safariland belt attachments or holsters.

*NOTICE regarding the KT SP Plate Drop Leg vs the Modular Holster Adapter for comparison: The KT SP Plate Drop Leg is our original design from 2015 and there are similar, or what we believe to be a rip off of our designs, that are now being sold as Modular Holster Adapters. We did our due diligence and conducted extensive engineering safety studies in 2015 and we have found the most ideal material to be thick thermoplastic. This allows for some give and flex in case user take a fall. Modular Holster Adapters are commonly made of rigid aluminum which may cause injury to the user in case of a fall. KT SP Plate Drop Legs are made here in Idaho USA while most Modular Holster Adapters are made in China.

*Works with Tactical holsters with the KT Universal Bolt pattern.

*Does not work with Concealment or low profile holsters.

*Holster sold separately.

The Science:

Why is a high ride height faster?

kt drop leg high speed

Because keeping the drop leg (holster) higher decreases inertia (rotational inertia) which takes less effort to move your leg.

A holster being further away (lower) from a pivot (your hip joint) actually makes your leg swing slower.

This concept can be broken down into these two key points:

1. Mass Distribution: The moment of inertia is calculated by multiplying the mass of the leg by the square of the distance from the pivot point (I = mr²). Because the distance (r) is squared, shifting mass further away from your hip (the pivot) drastically increases the effort needed to swing it. A drop leg (holster) positioned lower on your leg will feel a lot heavier.

2. Conservation of Angular Momentum: To start moving the leg, your muscles must generate enough force to overcome this inertia. A higher moment of inertia means a slower acceleration for the same amount of muscular force. A drop leg (holster) positioned higher on your leg will feel a lot lighter, which allows faster acceleration of your leg.

How Leverage Works:

In physics, this rotational force is called torque.

For example, if you apply a 2lb force at different distances, the torque changes as follows:

- At 2 inches from your hip to your handgun: 2 lbs x 2 inches = 4 inch-pounds of rotational force.

- At 6 inches from your hip to your handguns: 2 lbs x 6 inches = 12 inch-pounds of rotational force.

What this Means for You:

- At 6 inches, a 2 lb weight will feel 3 times heavier and will be 3 times harder to lift, hold, or rotate compared to placing it at 2 inches.

- Keeping your holster and handgun higher will allow you to move faster because it takes less effort.
