jaep1911 Posted November 24, 2014 Share Posted November 24, 2014 (edited) It has been two weeks since I got the Elite Limited 40cal and I am loving it. I got my 650XL converted to 40cal and made several dummy rounds for dry fire. When I release the mag after racking the slide (a dummy loaded in the chamber), the mag gets stuck in the gun/ magwell. As I rack the slide to load, the top round seems to push the next round forward in the mag and it holds the mag in the gun. This happens no matter how many dummy rounds remain in the mag. I cannot find any relevant threads. What is the cause for this phenomenon? Any remedy? FYI- Set-up: U-die followed by Dillon factory dies. COL = 1.125 ~ 1.130 Thanks in advance!

pivoproseem Posted November 24, 2014 Share Posted November 24, 2014 Bevel the very front of the flat underside surface of the slide, at the right angle below where the firing pin protrudes through the slide. Link to comment Share on other sites More sharing options...
jaep1911 Posted November 24, 2014 Author Share Posted November 24, 2014 pivoproseem - thanks for the interesting idea. Can you explain how the bevel works to prevent this problem from happening? Cheers Link to comment Share on other sites More sharing options...
Nealio Posted November 24, 2014 Share Posted November 24, 2014 If the bottom of the slide has s sharp edge it will catch and drag the next round forward. Link to comment Share on other sites More sharing options...
waktasz Posted November 24, 2014 Share Posted November 24, 2014 My gun did this when it was new if I used 180 gr TC bullets. Switching to 165s seemed to fix it. I've since gone back to the 180s and I very rarely have the problem show up now. I will try the bevel trick too. Link to comment Share on other sites More sharing options...
jaep1911 Posted November 24, 2014 Author Share Posted November 24, 2014 Thanks guys. I will file the edge and see if that resolves the problem. How much bevel are you talking about? 0.5mm?? I do not want to go too far. waktasz - thanks for letting me hold your Tanfo at the ESPS match the other day Link to comment Share on other sites More sharing options...
jmbaccolyte Posted November 25, 2014 Share Posted November 25, 2014 I'd knock the sharp edge off and shoot a couple hundred rounds. Then round it a little more and shoot some more. Perhaps not the most efficient way, but it works and its cheaper than filling too much. Link to comment Share on other sites More sharing options...
Nealio Posted November 25, 2014 Share Posted November 25, 2014 You can take a medium stone at a 45 degree angle and give it 4-8 swipes. Then radius/polish the area. This should get rid of any burs. You don't need to do a lot to fix the sharp leading edge. You just want to take enough material off so that when the next round pops up there is nothing sharp or "grabby" to push the round in the magazine forward. I also stone and polish the full length of that rib on the bottom side of the slide. Some of the slides I have had some rough spots on that rib, and on some the rib was bulged a little (.010") near the breach face so I took it down flat. This also reduces drag and helps cycling. Also as you shoot it more that rib gets polished on its own. Link to comment Share on other sites More sharing options...
Steffes Posted November 25, 2014 Share Posted November 25, 2014 I beveled the leading edge and polished the bottom surface as general cleanup on the gun before ever shooting it. It improves this situation immensely and it was downright sharp from the factory. Link to comment Share on other sites More sharing options...
jaep1911 Posted November 25, 2014 Author Share Posted November 25, 2014 Thanks guys. I beveled (approx 0.3mm) and polished it last night but did not polishing the entire bottom surface. I still had the same problem. I can see where the bullets have been contacting inside the gun, from the trigger plunger all the way down to almost the bottom of the magwell. I will polish the bottom surface, shoot more patiently and see how it goes. Cheers Link to comment Share on other sites More sharing options...
waktasz Posted November 25, 2014 Share Posted November 25, 2014 What OAL are you using? Link to comment Share on other sites More sharing options...
Nealio Posted November 25, 2014 Share Posted November 25, 2014 What mag springs? Stock? Link to comment Share on other sites More sharing options...
jaep1911 Posted November 26, 2014 Author Share Posted November 26, 2014 Waktasz - it is approx 1.125 ~ 1.130. Light crimp. All went in the gage and actual barrel. Nealio - It is a stock spring. Might be weak? The feed lip opening is 0.385. Pretty parallel. I am using Reinier plated bullets. Link to comment Share on other sites More sharing options...
Nealio Posted November 26, 2014 Share Posted November 26, 2014 No stock spring is fine. Someone here mentioned getting extra power mag springs, I thought it might be you. Link to comment Share on other sites More sharing options...
jaep1911 Posted November 26, 2014 Author Share Posted November 26, 2014 (edited) Well, I polished the hell out of the bottom surface and the failure to drop rate has gone from 100% to 10% (3 out of 30 cycles). I now see the light at the end of the tunnel. You guys are PHENOMENAL!!!! Thanks a lot. You can see where the bullets have been contacting in the gun here. And here is my new toy.

jaep1911 Posted December 2, 2014 Author Share Posted December 2, 2014 After 300 rounds, no more problem:) Thanks a lot guys! BTW, I just received a TF mag base along with a grams spring for the factory K-40 mag. At first, the mag did not want to seat completely so I loosened the magwell while having the mag in the gun and tightened the mag well. The mag now seats completely and comes out freely. Right now I can have 20 rounds in it and it is reloadable. I will let it sit for a while and see how it changes. I have read Henning's article about tuning the grams spring and follower (bend the spring to the right) but the kit seems to work without any changes to it. Am I lucky or missing something?

pivoproseem Posted December 4, 2014 Share Posted December 4, 2014 Hennings tips were for STI springs and followers in a tanfo tube and Grams makes a Tanfo specific follower now, if I remember correctly. Link to comment Share on other sites More sharing options...
Glk21C Posted December 4, 2014 Share Posted December 4, 2014 Yes. Per Beven don't mess with his followers/springs that are designed for a specific product Link to comment Share on other sites More sharing options...
