I just purchased a Mossberg 500 (Talo Edition #52134) and I want to secure it. I already have a gun safe and just ordered GunVault's BreachVault. However, I want a trigger lock as well. Does anyone have any recommendations on a good trigger lock that will properly fit the Mossberg 500? I know trigger locks aren't the most secure, but there are so many options out there, it's hard to find one that fits a Mossberg 500 without any excessive movement that may move the trigger. I found the Child Guard CS-100, which is adjustable, so I'll get a secure fit. However, it's plastic, so I was hoping to find something better. Any suggestions are welcome. Thanks!
