Tank you for your responses, i was away for a while from my pistols, shooting rifles so this events escaped my attention. To be honest, I am surprised with this events, I have few STI pistols, shot the more than any other brand ( about 5000 rounds/year), I have had only few problems with them. Never had to sent the gun in for major warranty claim but know people who cracked their slides and STI always stood by their products.
