The Rainbow Titanium finish defines this P238, pairing a stainless-steel slide with a multi-hued treatment on the slide and small controls, plus matching grip screws. The contrasting matte black anodized aluminum-alloy frame adds durability and a clean visual profile.
Built as a micro .380 ACP, it uses a single-action, locked-breech system with an exposed spur hammer and a manual thumb safety. Practical features include rear slide cocking serrations and an external extractor for reliable cycling.
Sighting is straightforward with dovetailed front and rear sights. The 2.7-inch barrel and 6+1 capacity keep the platform compact without sacrificing shootability.
Frame ergonomics include a beavertail profile with vertical backstrap serrations and black two-panel grips with longitudinal grooves. Factory markings include "SIG SAUER P238" on the left slide, "SIG SAUER INC., NEWINGTON–NH–USA" on the right slide, and ".380 AUTO" on the barrel hood.
The factory case label shows the model code 238-380-RBT2, matching the Rainbow Titanium series configuration. This example was made in the USA and includes one OEM flush-fit magazine.
