"Match" is usually a weapon that is made to closer tolerances for improved accuracy/performance. The "muzzle extension" is actually a compensator or more commonly refered to as a "Comp", which vents the escaping gases from the barrel in a predetermined direction to assist the shooter by reducing recoil and/or muzzle flip. And not all "Match" grade weapons have a "Comp", actually most don't.I realize Match means it has that little extension piece on the end of it, but what is that actual accessory called and what is it used for? I was told its a muzzle extension, but I tried looking on google for "beretta muzzle exentsions" but I dont find anything.
This of course is the short version or explanation, but really all anyone needs to know unless they are building the weapons.
