I'm checking to see if anybody else has had the thumb safety break. Part of my familiarization process is to practice my draw and presentation. A lot. Lol. Anyhow, the safety is pretty tight when new. It started loosening up nicely. A couple of days ago, I lost all spring tension in the safety. Now the safety won't stay engaged. I sent an email to Smith yesterday. We'll see how long it takes them to respond after the holiday.
