i guess its all based on de personal habit.. i rarely have my
fingers on de trigger even when i converted from m16s1 to sar21
half yr ago and my index finger is shorter...
de trigger guard of de sar 21 is slanted diagonal for some reason i
guess~ my finger is always on de trigger guard but not horizontal
as for those who hv longer fingers.. instead my finger slants
downwards but i dun see how it will compromise reaction time when
disengaging de safety~
perhaps de diagonally placed trigger guard a solution for shorter
fingers when i had problems wif de m16 trigger guard last time?

from SingaporeTyrannosaur:
Haha, maybe like the SAF, it's just an empty mag and the loaded one
is in the SBO... in which case, they, like us unlucky guard duty
personnel, walk around with the weapon in semi all the
time...
