First Impressions of Calculated Kinetics Glock 43x / 48 MOS Adapter Plate
The Calculated Kinetics Glock 43x / 48 MOS Adapter Plate is designed to bridge the gap between the Glock 43x/48 MOS platform and the popular Holosun K-series optics. This adapter plate allows users to mount the Holosun 407K, 507K, and EPS Carry, all of which utilize a modified RMSc footprint, onto their slimline Glocks without sacrificing the ability to co-witness with factory sights. The promise of a seamless optic mounting solution for these already excellent concealed carry pistols immediately piqued my interest.
My journey toward this adapter plate began when I decided to modernize my Glock 43x MOS. I’d been running the factory sights for quite some time, but felt like I was missing out on the advantages of a red dot optic. The direct mounting options were limited, and I was hesitant to send my slide out for milling.
Upon unboxing the Calculated Kinetics adapter plate, I was immediately struck by its solid construction. The black hard anodized finish looked durable and matched the factory finish of my Glock perfectly. The weight felt negligible, which is crucial for a concealed carry setup.
Several other adapter plates are available on the market, but I chose the Calculated Kinetics Glock 43x / 48 MOS Adapter Plate for a few key reasons. I’d heard positive reviews regarding its secure fit and ability to maintain a true co-witness with OEM sights. Others seemed flimsy or required aftermarket sights to achieve the desired co-witness.
My first impression was definitely positive. I was excited to get this plate installed and finally experience the benefits of a red dot on my Glock 43x MOS.
