I'm building a new G20SF into a .40cal USPSA Limited gun, and I'm using Arredondo +5 extensions. I haven't gotten to play with them very much yet, but I did have the follower hang up at the bottom of the mag once. I may have inadvertantly stuffed 21rds in it, so it may have been my fault. Most guys that use them for G22/35's have to either trim the followers to fit 20rds, or live with 19rd mags. Has anyone had any isues getting 20rds in a G20 mag? Can you reliably reload them (+one in the chamber) without extra force? Anyone trimmed followers to fit more than 20? I can live with 19rds, I just figured since its a game, why not get the most out of my mags. It would be nice to not have to reload during a 21/22rd hozer stage. (once I get it all set up, I'll post details, pics & give a report) . Wanna kill these ads? We can help!
