The only one that I know of is between the Fair grounds and Blue Angel Pkwy ON Pine Forrest.
Never seen a 5 shot mag marked LE only. Sounds kinda Hmmmmmm(????) to me.
Talkin' mags.....I see that MagPul now has a mag blocker that will limit their 20rd mags to 5 shots. Had them a couple of days ago at Mike's. $20 for 4 IIRC. --- SAWMAN
