Durable G&G Polymer Slide: The STP 45's slide is constructed using G&G's signature polymer, ensuring high durability for heavy use and abuse.

Patented PAI Hop-Up System: PAI is G&G's latest standard when it comes to pistol manufacturing to guarantee a high quality product when focusing on Precision, Accuracy, and Innovation.

The Precision aspect of this refers to the strict manufacturing process that ensures that each STP 45's hop-up utilizes a strict 0.019 millimeter dial adjustment, giving you the ultimate tuning capability.

The Accuracy aspect refers to the 39 dial adjustments that can be performed on this pistol, granting immense control over your BB's maneuverability capabilities.

Lastly, the Innovation aspect represents the entire system and design of the STP 45 as a whole. With these fine-tunable adjustment capabilities, the Hop-Up system is able to be adjusted a total travel distance of 0.74 millimeters, customizing your experience as required when using different weight BBs.

Aftermarket Part Compatibility: Developed with the TM Spec in mind, the STP 45 has high compatibility with many aftermarket parts.

One Tool To Rule Them All: Every STP 45 includes a single tool that allows you to adjust many aspects of the pistol.
