If you're willing to take the risk, go for it. Some would have you believe it's a small risk, but they aren't the ones spending your hard earned $500, are they? For those with problematic pistols, I have yet to hear of Glock actually replacing them. If you can't get it to work with updated mags and followers, I'm not sure what they'll do about it.
One solution would be to get a Gen 4, or put an aftermarket, heavier captured recoil spring into the Gen 3.
