Ragunya does a comparison and compatibility test between the newly released Tokyo Marui P320 Full Size airsoft pistol and the existing LayLax (SIG AIR) M17 model. It starts with an unboxing of the Marui P320 and an initial physical inspection, noting slight differences in characteristics such as grip thickness and the design of the under-barrel rail.

A detailed component-by-component breakdown follows, where the weight and structure of major parts are compared. The Marui's Fire Control Unit (FCU) is found to be significantly heavier and structurally unique, featuring different safety mechanisms and an externally adjustable hop-up system that sets it apart from the LayLax version.

The main conclusion is that none of the major components—including the slide, barrel, FCU, or magazines (gas and CO2)—are cross-compatible due to variations in dimensions and mechanisms. He advises users to treat the two pistols as entirely separate systems, though a bonus test confirms that both models successfully fit a real-steel Safariland 6379 RDS holster.
