The P226 was designed for entry into the XM9 Service Pistol Trials (Joint Service Small Arms Program), which were held by the US Army in 1984 on behalf of the US armed forces to find a replacement for the M1911A1. Only the Beretta 92F and the SIG P226 satisfactorily completed the trials. According to a GAO report, Beretta was awarded the M9 contract for the 92F due to better durability during endurance testing and a lower total package price. The P226 cost less per pistol than the 92F, but SIG's package price with magazines and spare parts was higher than Beretta's. The Navy SEALs, however, chose to adopt the P226 later.
