<span style="font-size: 11pt">I've had this 365 for a few months and recently noticed the 10 round mag was rusting. Called Sig Sauer customer service and they gladly replaced it. During disassembly I noticed rust around the mag release. This weapon is carried everyday mostly in an office environment and cleaned on a regular basis. I called Sig again and they are sending a replacement mag release. I've never had a modern weapon have this problem and I don't live near the beach or work around salt. Any suggestions on preventing it from happening again?</span>
