Stuff I've sold over the years...
M1 Garand (owed the IRS some dough that year)
Pedersoli 1874 Sharps replica (beautiful and fun, but too darn heavy to be practical)
6" S&W 686 (transitioned to bigger bore revolvers)
3" S&W 696 (just got too valuable on the market and couldn't resist the money they were bringing)
Customized Ruger MkII Govt. (replaced a 6" gun with a 4" gun that shoots equally well)
.44 mag Vaquero (fun, but I was starting to have too many .44s in the safe by then)
Winchester 88 in .243 (inheritance piece, but I'm a .30 cal. and up kinda guy)
Rem 700 in .222 (see above)
.45 Thompson replica (heavy as hell for what it did...if only it had been full auto I might have kept it)
Kimber Combat Carry (fell out of love with 1911s in general)
They were all fun and all, but I feel I have a more useful collection now overall.
The only one I really miss is the Garand, and even there....I never quite warmed up to the enbloc clips. Box mags make for a more practical gun.
