You're obviously missing something. I believe this is what you need.

All...
4 hand guns.
4 shotguns
4 Machine Guns
3 Rifles
3 Magnums
2 Super Special Guns
1 Stun Rod
1 Grenade Launcher
1 Rocket Launcher
3 Types of Grenades. Hand/Incendiary/Flash

I had the same problem until I bought a Rocket Launcher.

"2 Super Special Guns" ?
What are these two mate?
Also i the guns i found in the game should i buy them and see if that helps?

Gatling Gun / Bow and Arrow

Edit-
Also, you NEED to have them ALL in your inventory. You can't simply find one, sell it and then try to get the achievement. You need every weapon in your inventory.

Ive checked and i have them all, i might just buy every available weapon on the list and see what happens, im sure i have them all :S

You need to have them all in your inventory; Also make sure you have a Proximity Bomb...that's what held me up..

[Chrome30]

easiest way to make sure you get this is to upgrade all the weapons, because upon upgrading some weapons you get access to other weapons to buy i.e the hydra shotgun and like everyone has said, have them in your inventory. Good luck.

[Marco8YNWA]

Well il try and upgrade them all, but i know i have all the weapons because i checked them all with the achievement guide, i upgraded the ones that unlock wepaons, but il try upgrade the rest thanks for your help guys!

Proximity bomb? Make a list of everything in your inventory.

[Craigimuss]

This is puzzling. Mine unlocked fine on the item screen. Try storing them all in the item storage so they are together. The large silver revolver upgrade was the last one I needed. Easy to forget because revolvers are like handguns.

I had the same problem and I had all weapons,I think the problem is more if you play with a friend as he picks the weapon up then you buy it or you pick the weapon up and he buys it then it is not registered.I unlocked it when I re played the level with the L Hawk as that is the last weapon try that,good luck.I have said all this as I am trusting you have unlocked or bought all weapons.?

I played in coop and me and my friend took every weapon one at a turn, so he took shotgun, I took MP5, he took the next one, etc etc.
And achievement unlocked fine.

By the way, if you look at his gamertag he got the achievement and said nothing to us. Maybe a tip on what he was missing would be fun to know :p

You have to have all the grenadetypes of the granadelauncher too in you Inventory.
There are 4 types of it I think and the last one I got in Chapter 6.2..

[oldhouse]

There are way more than 4 type of ammo (5 or 6), and since those are just ammo they don't count for the achievement.

[Marco8YNWA]

i just got it guys after i upgraded all the weapons both achievements unlocked!

[turboskerv]

This happened to me as well beacase I sold all my grenades~

[Classick]

Does anyone know where I can find an incendiary grenade? It's all I need.

[BI0RAPTOR]

Honest people you do not need nade ammo or any kind of ammo to unlock the stock pile achievement,trust me and many others who have already said.I would love to know who set this false rumor off.I can not figure out why so many believe it to be true,,,madness.
