I find it helpful in removing the firing pin channel liner to put a few drops of gun oil down the channel and let it sit a few minutes. Then take a fresh and plump (not a skimpy off brand) Q-tip and douse it in gun cleaner, carefully jam it down the firing pin channel (it should be a tight fit), let sit for a few minutes and slowly remove it. Twist slightly as you pull it out. 9 out of 10 times it will bring the liner out unscathed for me. Good luck. I would also not bake the sights.
