Mossberg has been constantly improving the 500's design, and in 2005 they launched the Model 535. The ability of this shotgun's lengthened barrel to chamber 2 3/4", 3", and 3 1/2" shells was one of its most significant upgrades. The 535 can now be used in a variety of situations thanks to this fantastic addition. Although the 535's barrel isn't overbored, Mossberg gave users a variety of barrel choices, including smoothbore, rifled, vent fluted, and different lengths. The ergonomic and lightweight construction was maintained without sacrificing any of its capabilities. The 535 is equipped with twin action bars and an anti-jam elevator to ensure smooth operation. Their dual extractors are another fantastic addition. In addition to these top-quality extra features, Mossberg added sturdy parts and modern technology to guarantee that the 535 will continue to operate for many more years. Field stripping is remarkably simple, and it can withstand all types of challenging situations. Along with the innovative LPA Adjustable Trigger with a skeletonized blade, Mossberg also incorporated a visible and simple top-mounted safety.
