I'm wondering if anyone has any long term experience with the Magguts system specifically for the Ruger LCP. (The system that allows the standard length magazine to hold 7 rounds.) I've read a number of reviews that indicate it works reliably but haven't seen anything with reports of its durability in long term use (6 months +). Would this system be reliable enough to use for ccw? (particularly if you leave the mag fully loaded long term).
