The P238 is built on an anodized alloy beavertail style frame with checkered G-10 grips for comfort and a secure hold during rapid-fire usage. The stainless steel slide features the popular SIG SAUER slide serrations and improves overall performance and accuracy. Additionally, the contrast sights or SIGLITE Night Sights are removable and adjustable for windage. The sear and trigger return spring are redesigned to prevent spring over-ride of the ejector during assembly. The Nightmare model also features an all black frame and slide with natural stainless controls.
