    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)

    I've used them for a couple years now with no problems. I couldn't tell you how many rounds through them as I don't count, but upwards of 2000 ea. As with all new mags they were a little tight in the beginning but they'll loosen up with use.

    It's not getting 20rds into the mag that's the problem. The problem is reliably/consistently getting 20rds to feed from the mag without the follower hanging up inside the tube.
  4. Oh. I use them in my G20SF no issues. The Kriss 30 round mags have never fed correctly in my G30 however.

    No, in fact I only put 19 so it is easier to reload.

    I only load 19rds into the mags on my belt. I'll run a full 20rd mag +1, in the gun.

    Try some slide forward reloads w/a full 20rd mag...that's why.:supergrin:

    Good shooting

    I figured 20 reloadable was probably a no go, but I don't think I'll be at a disadvantage with 19rd reloads.

    I went for a quick indoor range trip last night to shoot my newest G20SF w/KKM 10-40 barrel. I had some 180gr Bear Creek TC's & 180gr Zero JHP's loaded to 1.20" OAL, so I loaded up all my Arredondo'd mags with 20rds each. I had to seat them with the slide open, but they all functioned fine (only tried it once each though). I may have to do some sanding on the inside edge of the bottom of the mag bodies if I start having issues.
