HoosierRoadie Posted January 4, 2020 Share Posted January 4, 2020 I have a 9mm Trojan I love, but I have a feeding problem when I insert a FULL 10 round mag during a reload from slide stop. The first bullet will frequently not feed when I hit the slide release. The round goes to the feed ramp and just stops. If I give it a bump, it feeds. If I rack the slide on a full mag, it feeds. I shoot IDPA and I really want to use the slide release. This happens with Wilson and Dawson mags, long factory loads, short factory loads and my reloads (147 Berrys, 3.0 gr Titegroup, 1.150 OAL) Any help would be greatly appreciated!

JMike Posted January 4, 2020 Share Posted January 4, 2020 Check your recoil spring and if necessary, possibly load them a bit longer would be my guess. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
HoosierRoadie Posted January 4, 2020 Author Share Posted January 4, 2020 I started with a 9lb spring and have worked up to a 12 thinking that 1st Round needed a little extra push, but I still have a the problem at seemingly random times Link to comment Share on other sites More sharing options...
223to45 Posted January 4, 2020 Share Posted January 4, 2020 I had a similar problem with my wife SA 1911.I polished the hell out the feed ramp, with a dremel and polishing compound. Seem to go away. Also polished the upper part of the chamber. You could probably do the same with 1000 or 1500 grit sandpaper.

jschweg Posted January 5, 2020 Share Posted January 5, 2020 I had the same problem with my Trojan/Tripp Mags whenever I loaded 10. 9 rounds would work flawlessly.With a full 10 in those magazines, the first one dips forward right into the feed ramp, especially when the mag springs are new.I was shooting flat point 147's at that time. I ended up switching to round noses and the problem completely disappeared. Sent from my SM-G960U using Tapatalk Link to comment Share on other sites More sharing options...
zzt Posted January 5, 2020 Share Posted January 5, 2020 I had to condition my mag springs by leaving them fully loaded for weeks before the first round nose dive disappeared. Loading shorter in the 1.145" to 1.150" range also helped. Link to comment Share on other sites More sharing options...
shred Posted January 5, 2020 Share Posted January 5, 2020 Lightly polish the top front corner of the magazine where the nose of the bullet would hit it on the way out. There's a little crimp there on the Dawson mags that acts as a tiny helper feed ramp. Make sure your bullets aren't contacting the inside of the slide stop when you hold it down, plus make sure it's not adding any drag to the slide when you hold it down to release. Stops on the ramp that can be bumped closed are often caused by a little drag somewhere in the cycle. Link to comment Share on other sites More sharing options...
rishii Posted January 5, 2020 Share Posted January 5, 2020 Shred nailed as usual also check your extractor tension and the breech face, too Much tension or a rough breech face may slow the round slipping under the extractor hook check if there is a slight radius on the bottom of the extractor hook, again the aid the round to slip under the hook Link to comment Share on other sites More sharing options...
cheers623 Posted January 5, 2020 Share Posted January 5, 2020 You might also look into getting a mag release with a higher shelf. Dawson used to make one, maybe still does. It positions the magazine slightly higher in the frame and allows the bullet to impact higher on the feed ramp. YMMV Link to comment Share on other sites More sharing options...
rishii Posted January 6, 2020 Share Posted January 6, 2020 One test to see where it’s hanging us is to remove the recoil spring and plug, reassemble, then load a mag with dummy rounds and hand cycle them through the gun, it will show you where e round is hanging up Link to comment Share on other sites More sharing options...
HoosierRoadie Posted January 6, 2020 Author Share Posted January 6, 2020 Thanks for the reply. First thing I did this morning. Short factory rounds dip down, hit the feed ramp and STOP. Long factory rounds (Geco 1.157 -1.160) ride on up the ramp with much less effort. I was trying heavier recoil springs, maybe I need longer reloads.

shred Posted January 6, 2020 Share Posted January 6, 2020 Feeding slowly by hand is going to show more problems than regular cycling. It's annoying as heck when trying to debug 9mm 1911s, but it also illustrates the main issue-- if there's any extra drag or anything slows down the slide, things don't work so well. Check your slide stop isn't adding drag anywhere when you hold it down as if on a reload because if that's how to make it malf, that's the first place to look. 1.125" is what I run my JHPs at and it works well.

Postal Bob Posted January 6, 2020 Share Posted January 6, 2020 My 9mm Trojan had a similar problem when I first got it. I sent the slide and barrel back to STI, and they recut and polished the feed ramp. ter that, no more problems. Some feed ramps on 9mm barrels are too steep for proper feeding, especially when a full 10 rd mag is inserted. The way the top round sits(stacking) in a ful(10) mag causes the problem.

N3WWN Posted January 6, 2020 Share Posted January 6, 2020 Are the rounds nose-diving or just hanging up on the ramp? Since it sounds like they're just hanging up on the ramp, check the feed lips. The front of the lips may be a little too narrow to allow the nose of the round to ride up the ramp without pushing down on the rest of the rounds in the magazine.

TimHawkins Posted January 7, 2020 Share Posted January 7, 2020 Hello, Local builder told me to load to 1.175 for STI and they worked great. Try a few dumbie rounds and hand cycle. Tim Link to comment Share on other sites More sharing options...

sauza45 Posted January 7, 2020 Share Posted January 7, 2020 Load up a mag and insert into the gun, press down on a hard service to seat the mag a little more and then rack the gun while still pressing down . If it loads then you should get the EGW mag release, it has a higher shelf. I had the same problem and the EGW solved it. Link to comment Share on other sites More sharing options...
TimHawkins Posted January 8, 2020 Share Posted January 8, 2020 (edited) Postal Bob, My mistake, it was for a 2011 and I wanted to us the same ammo in my 1911 and used 38 super mags [ no spacers] I have since starting loading to 1.155 and using Tripp mags in my 1911.
