It's my bane of playing a Guns-using character: the game simply gives you so many weapons, many of them useful, that I can never decide which to use. Right now I'm level 24 and stomping around the wastes with Lucky (I want a .45 Auto Pistol, but PSN store's still down, sigh...), but I play a soldier who carries a main weapon along with her sidearm. So far I've narrowed it down to:
The 9mm SMG w/ Light Bolt: While not the most powerful, it has a high rate of fire and, loaded with Overpressure rounds, is likely to tear a hole in anything it's pointed at.
The Assault Carbine: Since the patch reduced the spread and added an innate AP value to the 5mm HV rounds, I've been watching this gun more closely. While it has less general DPS value than the 9mm SMG, it is more versatile, and can take on any armoured enemy in short order.
The Hunting Shotgun w/ Choke and Long Tube: Slow but powerful, this gun also has a versatility to it that the auto weapons can't easily match, and with the perk Shotgun Surgeon (which I have), armour is of little concern. The only downside is the slow reload time if anything survives the initial fight.
What do you guys think?
PS: What's the point of 12 Gauge Coin Shot? Legion coins are semi-hard to come by unless you're regularly killing Legion troops, so it seems to me it has more value as a 'I'm killing Legion with their own money, tee-hee!' thing.
Keep Lucky over the .45 as long as your crit rate is decent. Lucky is just damn awesome and arguably the best side-arm in the game, despite having clearly inferior DPH to the Ranger Sequioa.
What I do is a gun/weapon for every situation:
I carry Pushy for close range encounters.
I carry the Gobi Sniper for sniping.
I carry an Assault Carbine for cazador swarms/other possible enemy swarms.
Then I carry Lucky and a Brush Gun because both of them are just incredibly versatile. Sometimes Lucky is superior to Pushy, for example, if it's close-range with multiple spread-out enemies. Lucky gets the job done quicker since I don't have to run to each individual target and can also have a superior DPS to the Assault Carbine if you just take the time to aim, since it's more powerful (with Cowboy and hand loaded ammo, 47 damage a hit with a 50% chance of 30 additional damage) but still fast firing shots instead of weak but constantly firing shots. Lucky also has the added benefit of costing practically nothing in exchange for being very deadly, whereas the Assault Carbine breaks down very quickly and requires a lot of ammo. Other times the Brush gun is superior to the Gobi Sniper, since a sneak attack crit from a Brush Gun hurts like hell.
Just try grabbing one for close range (fist, shotgun), one for long range (sniper, lever-action rifle), one for mid range (lever action rifle, service rifle variant), one for spray and praying (SMG, LMG, assault carbine or mini gun; your preference) and one that's versatile. (Lucky) If you can ask yourself "what can this gun do better than any of my other guns" and you can't think of anything, put it away.
