By all means fix it. Brownells sells a great product called "Hot Stuff" that is great for getting into those cracks. I'd also check that the back edge of the lock plates aren't a bit too tight on their inlet. Thus when the gun recoils it might be putting uneven pressure into the area where the cracks have formed. Of course it could be drying as well.
