Rambo Posted December 14, 2011 Share Posted December 14, 2011 I'm looking for some advice I just upgraded factory STI 38 Super mags with Grams Spring/Follower kits and Dawson +1 basepads. Following the article by Bob on Brazos website "Slide Lock Back or Not?" I have aquired a modified slide stop and modified the ledge on the follower at a 45 degree angle (similar to the picture). (I modified one follower and didn't modify another...perhaps I didn't file it enough as I have seen inconclusive differences between the two) The mags seem to be functioning flawlessly (with and without filed follower) except when trying to drop an empty mag. Roughly 50% of the time the mag will have to be slightly tugged. Note: This has never happened with factory mags with factory guts. I believe the follower is catching on the slide stop... Is this normal? How far do you file down your followers to prevent this? Or is there a different solution? I suppose...technically speaking I'm probably already in trouble on a stage if I'm dropping an empty mag but it's still disconcerting to know it might not drop free. Thanks in advance!

Singlestack Posted December 14, 2011 Share Posted December 14, 2011 Take the slide off and have a look to see what is hanging. Quote Link to comment Share on other sites More sharing options...
diehli Posted December 15, 2011 Share Posted December 15, 2011 Also, learn to snap your wrist as that'll tend to get an uncooperative mag moving. Quote Link to comment Share on other sites More sharing options...
Ming the Merciless Posted December 15, 2011 Share Posted December 15, 2011 If you've modified the Slide Stop and removed the ledge from the Mag Follower there is no longer any spring pressure from the Mag Follower pushing up against the Slide Stop, so any friction at all will stop the magazine from falling out. With even a single round in the magazine the Mag Follower will be holding the round against the bottom of the slide under spring pressure. Also check if the botton side of the Mag Release is dragging against the magazine, ie. does the magazine drop free after pressing the Mag Release if you very slightly release pressure on the Mag Release.

Rambo Posted December 16, 2011 Author Share Posted December 16, 2011 Thanks for the replies! Ming when you say remove the ledge...do you mean remove more material then in the Brazos article (like instead of a 45 degree angle the entire thing)? Are there any drawbacks to removing to much?

A63111 Posted December 17, 2011 Share Posted December 17, 2011 Couple of things to check. Some mag releases will pin the mag on release. Check to make sure that this is not happening. Depress mag catch and move mag in and out by hand. Do you feel any drag? If so can you let up a little on the release and have it free up. Dawson and others make higher quality mag releases that should cure this problem or you can carefully file off the extra. Some mags have bulges and or are out of square. Does it happen with all of your mags or only some? If only some check front to back dimensions. I just fixed 1 of mine that had a bulge on the front. It was only about .015 but enough to make the mag hang. Quote Link to comment Share on other sites More sharing options...
Rambo Posted December 22, 2011 Author Share Posted December 22, 2011 Thanks for the replies everyone...It appears that I just wasn't aggressive enough filing down the follower. They pass 'cold' tests now and they passed a brief 'live' test today. Thanks again! Quote Link to comment Share on other sites More sharing options...
