The Beretta became the M9. The Sig P226 tied with Berreta and while the per unit cost was lower than the M9 Sig could not match or beat the overall deal for spare parts, maintenance, etc. However the P226 was too good to be let go so it was soon after also adopted for use by the U.S. military and designated the M11. Initially is was used by the Navy, particularly the SEALS. But became dispersed through the Coast Guard, Air Force and in a number of special forces groups.
The Sig P228 is also in use by the SEALS.
