Great topic and efforts by OP. The guide is good, though slightly biased. How many beginners care if Glock is plastic and Beretta is metal? In fact there is no single valid reason to put M9 above G17 in this game. The video looks somewhat unrealistic, maybe the server runs some ancient DayZ version? Just can't imagine on which universe the zombies drop from single 1911 round to torso. Yeah they should from a 12mm round, but on DayZ 1.7.6.1 they just don't. Focusing on weapon choice, one should not forget the destination of sidearm in DayZ. It is killing zombies with single head shot. Hence, relevant features are: - Accuracy (spread) - Sights (field of view, pointing accuracy) - Loudness - Magazine size - Ammo availability Irrelevant or less important features: - Damage per shot (any will kill with head shot) - Firing range (the sidearm should not be used at distances larger than 50-70m anyway) - Fire rate - Recoil My personal choice is G17 with M9SD mags. The SD mags effect is very valuable for zombie infested dense spaces like cities or barrack / tent areas. However, not recommended for beginners (scarce ammo) and roleplayers (non-suppressed weapon not heard by z's? WTF?) For beginners, G17 with original ammo must be fine, just shoot from some range. Use zoom (right button or "+") when timing allows. Why not M9SD? It is still heard by players. A bandit will be more cautious approaching a player with M9SD (as a player with such weapon is assumed to not be a beginner). But most importantly, it is a lot less accurate than regular M9, let alone the G17 which accuracy wise can be compared only to revolver.
