If it were me I would keep it and add another. I have a Pro Hunter now and if I found a second Encore that was affordable, especially a .45 (I really want a .45) I would get it.
I have two older (not G2) Contender frames and a few barrels. I used to have 3 but I traded the third off for something else. I still wish I had the third one back. Unless you don't like the Encore system it seems like they're handy to have a couple of around.
