My collection right now (4 guns) and budget are such that guns I don't love but don't hate get traded out for guns that I love. The best example is the the M&P .40 I picked up new earlier this year, it was OK but after several range sessions the initial excitement faded down to neutral. I straight-traded that for a Beretta PX4 Storm SC, which was a great gun but pretty much duplicated the size and utility of another gun in my safe, the 6906, which I liked a lot better. I started hunting around for a trade on the PX4 and ended up trading into a Walther PPS .40 with night sights and 3 spare mags (I added some cash for that one) that I'm very happy with: I like the shooting characteristics, fits in a cargo pocket and can be packed anywhere (camping, day hiking) while being chambered for a round that will get the attention of anything I'm likely to encounter in my parts.
