Okay... I was at the range today and I was outnumbered on this one. I love the Garand, but a group of fellow shooters were arguing vehemently that it is superior to the M14/M1A. I have to disagree on that one.
The M14 is lighter, has a box magazine, doesn't ping (for what that's worth), and with the Garand, you can't "top off" the clip while loaded (actually you can but that's a whole nother story).
Anyways... Which one do you pick?
Sir, if you're comparing the actual military rifles in like condition, the M14 has the edge because of its greater simplicity and capacity. (BTW, the M14 is only lighter than the M1 when both are empty. A fully loaded M14 actually weighs a bit more than a fully loaded M1. The M14 is also longer than the M1.)
If you're talking about what's readily available today, the M1 wins hands down. It's mainly a cost/quality issue.
Springfield Inc. M1As have almost no GI parts in them any more and are basically expensive "M14 look-alikes." The older used M1As have mostly GI parts, but command prices equal to or above what the new guns cost. You can have a boutique M14 type built with all GI parts on a commercial receiver, but then the cost really escalates--$2,000 is the low end today. Good USGI M14 parts are very expensive (when you can even find them), as are quality magazines.
M1s are cheaper, and good GI parts (including receivers) are still available at decent prices, though some particular bits are getting harder to find. True, many M1s on the market today are well-worn veterans, and some are really beat. However, you can still rebuild a clapped-out M1 for less than a new M1A costs. And that's not even considering the clips vs. magazines cost differential.
If you just want an M14 type, by all means, get one. But you'll be money ahead to get an M1.
Hope this helps, and Semper Fi.
