regrets? back in 91, i sold an original colt 1911 (1917 prod date + full history of it from issue date) for $250. bought it a few yrs earlier for $200, so did make a profit.
before the clinton ban, was at a gun show & bought 2 russian sks's & a swedish m-96 mauser (all in mint condition) for $89 each. i should have bought more... still have the mauser & the better of the two sks's. sold the other to fund my ar-15 a few yrs ago. sold it for 5 times what i paid, so yeah, should have bought many more at the time.
