Based on my search results, the Glock 19 9MM 15RND Black Polymer airsoft gun seems like a great option for you at R579. This is the actual Glock 19 model you asked about, in black polymer with a 15-round magazine. It will give you an authentic experience replicating the real steel version. Another solid choice is the Umarex Glock 19 4.5MM CO2 BB Pistol for R3440. While a bit more expensive, the Umarex is gas-powered for realism and comes in the genuine Glock design. Both would be excellent choices to enjoy realistic airsoft simulations. Please let me know if you need any other details on these or have additional questions!
