Comments: This Swiss Arms pistol features a full metal construction for impressive durability and realism. There's a fully functional safety above the trigger guard to prevent unintentional discharge and besides safety, the pistol can be also fired in semi-auto mode.  The best thing about this gun might be the non-blowback operation. It makes the weapon highly convenient because there are fewer working parts. As a result, you get more reliability and a lower likelihood of malfunction.  On top of that, it makes the pistol highly accurate as well as there's no recoil associated as with blowback weapons, allowing you to easily home in on your targets.
