Forum:Weapon slots going away?

HI Folks... I started the game (Borderlands) with quite a few weapon inventory slots. As the game progressed, I'd substitute higher-powered weapons for the lower-powered ones I had near the beginning of the game. After awhile, most of my weapons were in excess of 200 damage. What's happened is that sometimes when I drop one weapon so I can pick up a 'bigger' one, Borderlands will tell me that my inventory is full. Generally I'll just drop another lower-powered one so I can pick up the 'bigger' one... drop two lower ones, get one much bigger one; not a bad deal.

Problem is, this practice appears to permanently reduce the number of storage slots. Just now, I went to pick up a higher-powered shotgun; I first dropped the one I had, then went to pick up the bigger one. Can't; inventory is full. Dropped another weapon, and *still* couldn't pick up the bigger shotgun. Gave up, and went to retrieve the two that I just dropped... and it STILL says my inventory is full, so now I can't even retrieve the ones I had just a minute ago and dropped to get the bigger gun. Lose Lose Lose! What's up with that? I'm gradually being reduced to just a few high-powered weapons instead of the low, medium, and high assortment I had built up over time.

So what am I missing here? Obviously there's something in the game mechanics that I'm not picking up on. Can anyone shed any light on what's going on here?

Thanks!!
