I am kind of in that boat.
I have everything that I want. I have my carry 686 that I run IDPA with as well, I have a glock in 22lr for rimfire fun, and a model 36 that the gf enjoys.
I want to buy new guns, I really do. I even sold some stuff to free up the cash to buy a new one.
And then I realized that there is nothing that I want. or more pointedly, there is nothing I will USE. I think R8s are neat and I keep an eye out for one, but if it wont get carried, then it is just a pricey range toy, and playing with something other than my carry gun doesn't really appeal to me.
So I almost feel like I am twisting my arm to spend the cash I set aside for one. There is just nothing that wows me, and everything else is just way too high and getting higher by the month.
