Gmod Addons To Defend My Shop!

I own a game store in DunCity, and I'm gonna need some defense! I sell old school games ranging from S.T.A.L.K.E.R and Resistance. I also sell PCs! No Macs.

YOU SEE THIS? THIS. IS. MY. BOOMSTICK!

That's my Boomstick. Think this is good defense? Well, I'd question that, there may be better weapons.

And when everything goes wrong, I kill myself!
   
If it's all the same to you.

Or should I get an SMG? More compact, and more damaging at the same time!
Damn, not many Sweps that I want. Should I find more defense, or do I have everything I need with the Kermite's shotgun pack?

I'll keep searching. And I found a new map where I can move to when this old map gets, well, old.

So goodbye!
