STI Costa Carry Comp - Costa Ludus Collaboration - 9mm 2011, 4.15 in, Integral Comp, 17+1, Rail
This Costa Ludus collaboration model is a pre-Staccato, STI-built 2011 in 9mm with the integral Carry Comp island system. It pairs a carry-length 4.15 in barrel with an island comp that fixes the fiber-optic front sight to the block, plus a full-length dustcover with a multi-slot Picatinny/1913 rail. Marked with the Texas-outline STI logo and COSTA LUDUS wordmark, it offers 17+1 capacity and a configuration tailored for fast, controlled shooting.
The compensated, ported barrel/comp assembly measures approximately 5.10 in overall, with slide lightening and port cuts near the muzzle to reduce reciprocating mass. A Heinie rear notch teams with the island-mounted fiber-optic front sight for a crisp sight picture that tracks with the comp block.
The metal frame carries a full-length dustcover and rail, an extended/flared magazine well, and a tan polymer 2011 grip module with aggressive texture. Front and rear cocking serrations aid manipulation, and the octagonal, flat-faced muzzle block gives the Carry Comp its distinctive profile.
Controls include an ambidextrous thumb safety and a beavertail grip safety with a memory bump. A skeletonized, serrated-face trigger and a skeletonized commander-style spur hammer round out the performance-focused fire control setup. Built in the USA during the 2010s, this example reflects STI’s collaboration with Costa Ludus on the double-stack 2011 platform.

The Costa Carry Comp integrates a single top-port comp island with the front sight fixed to the block, keeping the sight picture stable relative to the compensator. Slide lightening and port cuts at the muzzle area complement the comp system for flatter tracking and quicker recovery. The rear sight is a Heinie notch, pairing cleanly with the fiber-optic front.
The frame features a full-length dustcover with a multi-slot Picatinny/1913 rail for mounting accessories, plus an extended and flared magazine well to streamline reloads. The tan polymer 2011 grip module has aggressive texture for a locked-in hold.
Safety and fire-control components are purpose-built: ambidextrous thumb safety, beavertail grip safety with memory bump, a skeletonized serrated-face trigger, and a skeletonized commander-style spur hammer. Front and rear cocking serrations support confident slide manipulation.
Branding details include the Texas-outline STI logo on the slide and the COSTA LUDUS wordmark. This pre-Staccato, USA-made 2010s example is chambered in 9mm with a 17+1 capacity on STI’s double-stack 2011 platform, combining collaboration-driven design with carry-length dimensions.
