I have lifetime warranties on Walther and Ruger weapons that I have had to access. Both were fast, easy, and no hassle. For the Ruger it was my fault for putting after market target grips on my MkII. They evaluated the weapon, wrote a detailed explanation, and even put new factory grips on the weapon free of charge. This was all before the internet and it was all handled via phone. S&W provided me with sized grip pieces for a police trade-in M&P for free without hesitation. My experiences with each of the three were all flawless and that is why I own more than one from each company.
