The M-1 is a neat gun, I have one that is an early Winchester model with the safety and mag release nearly next to each other. I hope you have better luck with the CETME than others I've heard about, there seems to be quite a discrepancy in their quality control. Of the two pistols there isn't much to be said, the Springfield is one of the better buys out there and the S&W is definitely big (though I hate those types of rubber grips and would replace them soonest). You got a real steal on them from your buddy and owe him one for the deal.
