Here is information on the FBI 1076 that the pistols'fans may find interesting.
• the FBI 1076 was reportedly based on the Model 4506 but all three contract test pistols submitted to the FBI in 1989 were clearly marked/stamped 1006s and were modified to contract specifications
• one of the test pistols had a 3 ½ barrel
• the FBI took delivery of only approximately 3,500 1076s; approximately 1,000 were returned to S&W under warranty. These 1,000 pistols were later shipped out by S&W as used guns to distributers and are the ones on the market today
• the FBI, and other law enforcement agencies, contracted for 1076s with no magazine disconnect safety
• FBI 1076s may have grooves or checkering on the fore-grip
• FBI 1076s may have no caution statement or the law enforcement caution statement. There is no documented FBI 1076 with the civilian caution statement
• the FBI 1076 test pistols did not all have serial numbers beginning with "TEU." It does not stand for "Test Evaluation Unit"
• the FBI 1076 serial number prefixes include TEU, TEV,TFE, TFF, TFH, TFK, TFL, TFN, TFP, TFX, THB, and THC
• the FBI 1076 never requested a "special trigger group." It is not in the contract. It is a myth that the FB1076 has a special trigger. The confusion may be a result of engineering changes required to install the de-cocker
• the FBI did request that the contract pistol be equipped with a SigSauer type frame mounted de-cocker
• the FBI 1076 was included in the 10/91 frame-mounted de-cocking lever recall
• the 2,500 1076s ultimately accepted by the FBI were hand assembled in the Performance Center using only the best parts available
• the belief that these Performance Center pistols had $2,500 - $4,500 worth of gunsmithing done is a myth
• it is believed that nearly all of the 2,500 pistols were destroyed by the FBI. The remaining FBI 1076s in the possession of the FBI are essentially demonstration pistols only
• A few very senior Special Agents that are on the job are still carrying their 1076s. When they retire their pistols will be destroyed as surplus property
