Hey there! After reviewing the search results, it looks like the Super Force Airsoft Gun Colt 1911 With Silencer for R199 would be a great option if you're looking to add a silencer. This pistol already comes with a silencer pre-attached, so it will have a stealthier sound right out of the box. The price is also very affordable if you're on a budget. Let me know if you have any other questions!
