Seen a lot of people recommending the Talon grips, but the pics are usually of squeaky clean looking grips that obviously haven't seen much use yet. Anyone have more trigger time with Talon grips installed? Or at least had them installed for a longer period of time? I'm just wondering how well they hold up over time. I know it's only a $10 investment, but I don't want to waste my time/money on them if they start slipping around the grip after a short period of time.
