Chambered in \u003cstrong\u003e4.5mm \/ .177 calibre\u003c\/strong\u003e, the Panther 31 combines a rifled steel barrel, conventional spring-powered piston system, adjustable two-stage trigger and durable synthetic stock in a straightforward single-shot design. The Panther specification was developed as the synthetic-stock counterpart to Diana's traditional timber-stocked Model 31, retaining the same core mechanical architecture while providing a more weather-resistant sporting configuration.\u003c\/p\u003e\n\u003cp\u003eThe Panther 31 uses a self-contained spring-piston powerplant, meaning it requires no external air cylinder, CO₂ cartridge or charging equipment. Cocking the break-barrel action compresses the internal mainspring and simultaneously provides direct access to the breech for loading a single pellet. Once closed, the barrel locks back into alignment with the receiver ready for the next shot.\u003c\/p\u003e\n\u003ch2\u003eDiana Panther 31 .177 Key
