It is likely that \"System Zero\" will be used in KSC's CO2 series from now on.\u003c\/p\u003e\n\n\u003cp\u003e The Mk23 is the largest handgun from KSC. It looks like it will be a powerful blowback model worthy of a non-standard military gun, and it's a model I'm really looking forward to.\u003c\/p\u003e\n\n\u003cp\u003e The power source is CO2 (liquefied carbon dioxide), which is tenacious even at low temperatures, and it uses the largest big-bore cylinder (inner diameter 15.5mm) of any KSC pistol.\u003c\/p\u003e\n\n\u003cp\u003e Another noteworthy feature is the mechanical feel of the short recoil of the heavy barrel unit.\u003c\/p\u003e\n\n\u003cp\u003e In addition, the adjustment functions of the front and rear sights are realistically reproduced, and the dummy movable firing pin extractor and other features enhance the realism when held in the hand.\u003c\/p\u003e\n\n \u003cp\u003eThe huge slide blows back with the overwhelming power of CO2, making this the definitive SOCOM pistol that can be enjoyed all year round, with little effect from the outside temperature.\u003c\/p\u003e\n\n\u003cp\u003e The real-size magazine holds 12g CO2 cartridges, just like a regular CO2 gas gun.\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e I was thinking that KSC hasn't released any crazy limited edition custom products for a while, but it turns out they were planning a product like this.\u003c\/p\u003e\n\n\u003cp\u003e This time, the material is ABS, but the Mk23 is extremely popular in its HW version, which allows you to feel its overwhelming weight. I am well aware that HW is a material that is weak against impacts, but as the world's first heavyweight CO2 blowback gun, I can't help but look forward to its future commercialization.\u003c\/p\u003e\n\n \u003cp\u003eEither way, I believe this is a highly sought-after item that toy gun enthusiasts should have in every household.\u003c\/p\u003e\n\n\u003cp\u003e I'm really looking forward to it too.\u003c\/p\u003e\n\n\u003cbr\u003e\u003cbr\u003e \u003cspan\u003eWeight: 950g\u003c\/span\u003e\u003cbr\u003e \u003cspan\u003eTotal length: 245mm\u003c\/span\u003e\u003cbr\u003e \u003cspan\u003eMagazine capacity: 27 rounds\u003c\/span\u003e\u003cbr\u003e \u003cspan\u003eFiring mode: semi-automatic\u003c\/span\u003e\u003cbr\u003e \u003cspan\u003e*A separate 12g CO2 cartridge is required (JASG genuine gas cylinders are recommended)\u003c\/span\u003e","brand":"KSC","offers":[{"title":"Default Title","offer_id":43784161820931,"sku":"F800","price":25520.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0405\/1684\/5735\/products\/F800.jpg?v=1677750563"},{"product_id":"ksc-mk23-socom-pistol-27rounds-co2-magazine","title":"[KSC] MK23 SOCOM Pistol 27-round CO2 Magazine","description":"\u003cp\u003e KSC MK23 System Zero Series 27-round CO2 Magazine\u003c\/p\u003e\n\n\u003cp\u003e Compatible with 12g CO2 gas cartridges (sold separately).\u003c\/p\u003e\n\n\u003cp\u003e *We recommend using genuine JASG gas cylinders.\u003c\/p\u003e","brand":"KSC","offers":[{"title":"Default Title","offer_id":43784240496899,"sku":"G800","price":5790.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0405\/1684\/5735\/products\/G800.png?v=1677751058"},{"product_id":"ksc-mk23-socom-pistol-muzzle-guard","title":"[KSC] MK23 SOCOM Pistol Muzzle Guard","description":"\u003cp\u003e Reproduces the parts used on a real gun to protect the muzzle screw.\u003c\/p\u003e\n\n\u003cp\u003e Can be used with all KSC MK23 models.\u003c\/p\u003e\n\n\u003cp\u003e The 16mm positive thread allows for free installation direction.\u003c\/p\u003e\n\n\u003cp\u003e * Also compatible with USP45 Tactical.\u003c\/p\u003e","brand":"KSC","offers":[{"title":"Default Title","offer_id":43784259371267,"sku":"N380","price":1490.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0405\/1684\/5735\/products\/N380.jpg?v=1677751582"},{"product_id":"ksc-mk23-socom-pistol-co2-abs-co2-gas-blowback-frame-cerakote-fde","title":"KSC MK23 SOCOM Pistol (CO2) with ABS CO2 Gas Blowback and Cerakote FDE Frame","description":"\u003cp\u003e This is an original custom H\u0026amp;K pistol FDE frame, which is also commonly seen in real guns, made with the same Cerakote finish as the real thing, based on the KSC Mk23 CO2 blowback.\u003c\/p\u003e\n\n\u003cp\u003e The combination of a black slide and Cerakote FDE frame creates a stylish two-tone color that will satisfy your desire to own it.\u003c\/p\u003e\n\n\u003cp\u003e This time, we created a Cerakote painted version to reduce the \"cheapness\" that is unavoidable with ABS material.\u003c\/p\u003e\n\n \u003cp\u003eInitially, I had planned to paint the slide, but I gave up on the idea because the original markings on the slide were too thin and would have been obscured by the paint, and the high temperature baking process would have caused some deformation of the slide.
