Strike Industries SMC Charlie Top Rail Features The Strike Industries SMC Charlie Top Rail is machined from steel for durability under repeated mounting and dismounting of accessories then finished in black to match the look of a factory Sig Sauer P320 slide. Its design is built specifically around compatibility with an extended charging handle for P320 slides so shooters running that upgrade do not have to choose between a better charging handle and extra rail space. That attention to fitment means the two parts are meant to be run together rather than being a generic rail that happens to clear the handle. Because it is purpose built for the P320 platform installation is straightforward for owners already familiar with slide level accessories. Despite being built from steel the Top Rail weighs only 0.411 ounces a negligible addition that will not meaningfully affect the pistol s balance or cycling. That light weight matters for shooters who want added mounting capability without the muzzle heavy feel that bulkier steel parts can introduce. The rail s steel construction also means it will hold up to the repeated clamping and unclamping of optics lights or other accessories mounted along its length. For P320 owners looking to expand their slide s capability while keeping an extended charging handle in play the Strike Industries SMC Charlie Top Rail is a focused well matched upgrade.
