Ruger EC9s problem...Solved post 9

[5-Shot]

I was at my regular Thursday at Buds last week and, much to my surprise and delight, they had reasonably priced EC9s on the display wall. Obviously I bought one. Today was the first time I got it to the range. Much to my disappointment it locked open prematurely at least once on every magazine. I'm pretty sure my thumbs were well clear of the release. Any ideas or suggestions?

Other than that it was fine.

Based on my experience, my honest advice is to trade it for a G43 or Sig P365 or something similar.

Life’s just too short to have guns that don’t work properly every time.

Number of questions

Three questions spring to mind:

1) What ammo were you using?

2) Does it do the same when somebody else with different thumbs shoots it?

3) Did you try shooting thumbs down?

I have the LC9s which is essentially the same, and it has never locked open early on me or my wife.

Reloads with 115 grain Sierra, 5.0 grains Unique, LOA 1.070
and Remington 115 grain law enforcement/military training ammo.

No one else shot it and my thumbs were pretty much out of the way.

I just read elsewhere about fat nosed bullets catching the projection that lifts the slide stop. I'm going to check that.

90+% of these problems are ammo or Magazine related.

I've had my EC9s for over two years and have never had that problem. I shot it yesterday after pocket carrying it without firing it for about a year and it did just fine, pocket lint and all.

Problem solved...maybe. The little tab that lifts the slide stop was indeed rubbing on bullet noses. I ground a few thousandths off and went the back yard a brief test. It was the first time that pistol successfully made it to the end of a magazine. A full test will be conducted at the range next week.

Co-worker has an EC9s, well worn, and it never malfunctions. They are good SD carry pistols.

As was mentioned in one of the responses above some EC9s's have a tab on the slide stop that is too long. That tab is to catch on the magazine follower when the magazine is empty and push the slide stop up. Mine was just long enough to rub on the nose of loaded rounds as they rose up toward the chamber. Ever now and then one would rub hard enough to lock the slide back. A few passes with a Dremel did the job. I fired 5 different brands of ammo today at the range with zero problems.

Thanks.
