No addiction here, but so far I've had 3 S&W revolvers and now 3 S&W semi-autos.
If I have an "addiction", it is conceptual. I have fallen for the 3rd generation Smith semi-autos, in a big way. But, so far, I've kept it under control (only 3 so far).
I like used guns better than new, anyway (so it all fits perfectly). I am staying out of the gun shops right now, lest I find any more overlooked polizei trade-ins or other neglected 3g's.....that need a good home.
