Effective Blunderbuss loadout for the support ?

[Restally]

If absolutely pointless for the demo in my case, I find the gun really fun to play for the support : the grenade launcher making it great to deal with large amounts of weak zeds (I'm looking at you, crawlers) and break through rioters helmets, and the secondary shotgun fure mode being quite powerful and quite good to deal with larger zeds sur as the fleshpound.

Now the real problem i have with it is : the gun as a incredibly small 3 shots magazine, which pushes me to lean more toward "High Capacity Magazine" instead of the usual "Tactical Reload", as having a 5 shot mag is definitely more comfortable and the bonus reload speed coming from the other skill is really hard to notice.

But having to run this skill pushes once again to run more with mag-fed shotguns, which make me feel trully more limited in my choice of an arsenal . . .
The medic shotty give me more jack of all trade options but isn't as effective as other shotguns, the AA12 benefit the most of the high mag skill but is incredibly heavy and expensive, and i don't see the point playing the HZ12 if the blunderbuss already take care of the weaker mobs . . .

So i wanted to get your advise on it, which 1st skill should i choose for it and what weapons should i bring with the Blunderbuss ?

I always prefered a higher magazine capa over a higher reloadspeed and this is working nice for me.
And yes, you're right 5 shots for the blunderbuss is great.

Support was one of the perks i played very infrequent, this has changed with the blunderbuss (and tbh with new neon skins^^)

My preferable loadout currently is:
doublebarrel (medium sized and sc), vlad (long distance and small zeds), blunderbass (mobs, qp, fp). Well suited for every situation and enough weight left to upgrade and buy 101.
Its a completely new loadout for me. But its very nice to play ;-)
