This KTS is a great way to personalize your KNEKT and instantly provides a wider contact point for your finger. Custom designed and made in the USA to perfectly fit the contours of our triggers. The KTS is CNC machined from marine grade aluminum and then anodized to enhance corrosion resistance. It is firmly held in place by 2 stainless steel hex screws and attaches in seconds using the supplied hex key. The KTS fits the New GP3 v2 as well as the GP3+, GPLT, GPDL and the GP4. It does not fit the original GP3.
