Frequently Asked Questions

What is the purpose of the Kyro Defense thinner backstrap for the Glock 43X?

The Kyro Defense thinner backstrap is designed to provide a slimmer grip profile for the Glock 43X. This modification aims to improve ergonomics, allow shooters to get higher on the backstrap, and help prevent 'slide bite' by reducing hand interference with the slide's movement.

How do you install the Kyro Defense thinner backstrap on a Glock 43X?

Installation involves removing the original trigger housing pin using a punch, then fitting the new thinner backstrap. A slightly larger pin, provided with the kit, is then inserted and secured with a nylon-tipped hammer until flush with the frame.

What tools are needed to install the Kyro Defense thinner backstrap?

You will need a punch set to remove and install the pins, and a nylon-tipped hammer to gently tap the new, larger pin into place without damaging the firearm's components. The kit includes the necessary replacement pin.

What is 'slide bite' and how does the thinner backstrap help prevent it?

'Slide bite' occurs when the reciprocating slide of a pistol nicks the web of the shooter's hand. The Kyro Defense thinner backstrap allows for a higher grip on the firearm, creating more clearance between the hand and the slide's path, thus reducing the likelihood of this injury.
