I'm wondering if anyone can give some insight on what I think could be an issue with the magazines for my ECO 9mm. 

I'm having a heck of a time trying to drop the magazine if it still has cartridges in it.  I actually have to pry it out using the floor plate.  And, I have always had to slap in a loaded magazine pretty hard.  Upon closer inspection, I noticed the magazine lips bow out when it holds cartridges causing it to get caught up in the magazine well when I try to remove it. 

I can insert and remove an empty magazine without any problem. 

I have about 300 rounds through this gun so it's still in the break-in period.  I am still having failures to return to battery (common in the break-in period) but this has decreased in occurance from once every 10 rounds or so to about once every 25 rounds.

I have not had any failures to feed or failures to extract.

Has anyone experienced a problem like this?  I'm thinking the magazines may be faulty.

Thoughts anyone...

My ECO in .45 would not drop the magazine and it turned out to be a metal burr in the mag release button. My gunsmith polished the area and no problems to date .That happened about two years ago.

My titan 10mm was having issues with dropping a loaded mag, I too had to pry the mag out.  It is getting better, however it does feel as though there may be a burr on the mag release button, it has a bit of a "gritty" feel to it.  It is getting better (200 rounds)  I also experienced failure to go into battery, but it is much less often.

Have you tried a different brand magazine (just to isolate the problem)?

Ooops, I just realized that this is an ECO 9mm, so getting a different brand magazine may be a problemfrown

I would not overlook a problem with the magazine release, that might be your best first opportunity. Don't hesitate to touch base with DW in Norwich, I understand the need to break in the gun, but 1 in 25 at 300 rounds and not releasing a partially loaded magazine seems a little ???

I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

The only difference would be the spring is compressed in an anything but an empty magazine.  Take the top half off and try a loaded magazine in the mag well.  I'm curious to know where its binding up and it's easier for you to see what's going on with the top half off. You should be able to narrow it down between the feed lips being too wide or an issue with the button side of the magazine catch- it should be curved and smooth.  Are the magazines Checkmate or Metalform? 

I chewed on this some more....  the FtF rate is too high, particularly if you are following break in procedures.  Now I'm wondering if all your magazines are fully seating?  When you have a loaded mag and insert it; are you certain the magazine catch is fully engaged?  The release button should protrude the same distance, after inserting, on all magazines. Do it with the top half off again....  Safety first, particularly in the home.  Also a good idea if you have antique mirrors around.  Don't ask how I know... 

Technically, the glass is always full; half liquid, half air....

Good Morning All,

I would look at the mag release first, mine is working it's self out (I dry fire with a full mag of snap caps, rack, safety on, safety off, trigger pull, rack slide, safety on, eject mag, replace "spent" snap cap, replace magazine, repeat ad nauseam.)  And the magazine issue has stopped.  Regarding the failure to go into battery, I would take another look in a hundred rounds or so.  The fit on the slide of my Titan is so tight, you have to pull straight back to rack it, any non linear torque would cause it to bind; the first hundred rounds or so you could see the slide go into battery in slow motion after ejecting, it was kinda weird having it return to battery with a subdued click, almost like it was operated by hydraulics.  What type of lubricant are you using?  My friends with race guns recommend "Mobil One" synthetic for the slide and workings.  With all that being said, I suppose even Carol Shelby sent out one or two cars with a loose lug nut, if the problem is not resolved I would follow Steve CT's advice and contact DW.

Regards,

-d 

p.s. if anyone is following this thread I realize the original Cobras came with splined knock-off wheels, but the metaphor did not work well that way.

Upon further review last night, the function of my loaded magazines is getting better but releasing the mag has intermittent issues.  Sometimes I can depress the release button easily with the thumb of my shooting hand (maintaining a proper grip) other times it takes the force of both my thumbs.  I shall take a look at the release button and see if it needs to be stoned.  I do see some scratches on the magazine (on the left or release side) some of the scratches are smooth, linear, closely spaced and uniform, with a few rougher, non linear looking scratches that may indicate a burr or hang up.  I will post pictures and results if successful.  

Regards,

Remember that your magazines actually "catch" and "release" on the right side of the magazine, the tab that retains the magazine is on the right. I would check inside the magwell, grip screw bushings, and the "left"  side of the mag release
