Viridian's INSTANT-ON technology activates the laser automatically when drawing from compatible holsters, providing immediate target acquisition without fumbling for buttons. Green laser visibility outperforms red in most lighting conditions, making this an excellent choice for home defense and range training.\u003c\/p\u003e\u003cp\u003eThis model mounts directly to the Ruger-57's accessory rail without tools, featuring a low-profile design that maintains the pistol's handling characteristics. Powered by a single 1\/3N lithium battery, the unit provides up to 1 hour of constant-on runtime. The ambidextrous activation switch allows manual control when not using INSTANT-ON capable holsters. Constructed from reinforced polymer with a tactical finish.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Visible Green Laser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWavelength:\u003c\/strong\u003e 532nm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation:\u003c\/strong\u003e INSTANT-ON (holster-activated) or Ambidextrous Manual Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Type:\u003c\/strong\u003e 1\/3N Lithium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRuntime:\u003c\/strong\u003e Up to 1 hour constant-on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type:\u003c\/strong\u003e Direct Rail Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearm:\u003c\/strong\u003e Ruger-57\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDot Size:\u003c\/strong\u003e 0.5\" at 50 feet (typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 0.8 oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Viridian Weapon Technologies","offers":[{"title":"Default Title","offer_id":47943845380351,"sku":"LAS912-0025","price":122.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2867500.jpg?v=1766603482","url":"https:\/\/doublestackstore.com\/products\/viridian-e-series-grn-laser-ruger-57","provider":"Double Stack Store","version":"1.0","type":"link"}
