Put it in a vise and crank 'er down, substitute your hammer for the gun (be sure its unloaded of course) Joking aside
I Clean off all the factory lube, and lube the gun with CLP a nice fine smooth coat don't overdo it (metal touching metal=lube) with a few exceptions, clean out the striker channel and leave it dry or dab oil on a rag and put wipe it on the spring, fire about 200 rds through it, buy more ammo and repeat...(If that doesn't work im sure a pair of JAWS will work well) to break your gun...
EDIT: Don't put your Springfield in a vise unless you want to buy a new vise
