SR40 Jamming

[jlagesse]

Just bought my SR40 yesterday. When i got it home I broke it down and cleaned it. I put it together and broke it down once more and spent the evening familiarizing my self with all the bells and whistles and moving parts.

I went to the range today with 100 rounds of American Eagle .40 S&W rounds, 165 gr. Loaded the magazines with ten rounds each. in the first 40 rounds the pistol jammed 4 times. Looking for a little insight in to what might be going on. Brought the pistol home and throughly cleaned it.

I have owned revolvers but never a semi automatics but do have experience handling them and have taken the NRA Basic Pistol Course. Any advice on what may be going on and what I can do to not have this problem. I have read great things about the SR40 but was a little disappointed today with its performance.

Could be any number of things. Is it a feeding or ejecting issue? You'll have to be more specific for anyone to diagnose the problem without seeing it. On new pistols, the magazine is often the problem. Try loading them to max and letting them sit a few days. Please give a more detailed description and I'm sure someone can help you out.

Sounds like a tough problem to diagnose. Try another 100 rounds. Load the magazine fully and send us some pics. of your next attempt. If you can't get better results in the next 100 rounds, take the gun back to the dealer. Hard to believe 10% of your rounds are failing, and you don't talk about what kind of "jam" it is. I'd like to help you out, but this is one of those nebulous posts that has enough detail to sound plausible but not enough detail for anyone to do anything about, which to me means that as a first time post, it's a ringer.

Why would you load the magazines with ten rounds each? Try loading them to the full capacity with the loader and then go and shoot the gun.

You are the only person in the world, to my knowledge, who is reporting a 10% malfunction rate on a new SR40. If it persists into the next box of ammo., send it back, by all means. Something is definitely wrong with the gun if the "jams" persist.

It is a feeding issue. The ound is getting stuck on the upper left side of the ejection port.

With both magazines? If it is, then something is definitely wrong with the gun and you should bring it back immediately to whoever sold it to you or call Ruger and ship it back to them. Sounds like you've got a bad gun there. Easy to solve.

There should never be a 10% failure rate on any of these guns. If that's what you're experiencing, the gun is unsafe. Call Ruger customer service, pack it up and send it to them and come back with a report on what they replaced. They will send you a brand new UPS shipping label if your new gun is really malfunctioning that badly. They will also tell you exactly what is wrong with it, and they will repair it at no charge. Do not do anything else to the gun. Don't fire it any more. Send it back.

Try taking the gun back to whoever you bought it from and ask *them* to replace it with a brand new pistol. Who did you buy it from?

Yeah it happened with both.

I bought it from Gander Mountain.

I have cleaned it and oiled it and loaded each mag with ten rounds.

I am going out to the range again in a couple days.

If you're experiencing 10% FTF on a new gun there's something wrong with that particular pistol. It shouldn't ever happen. Since it's happening with both magazines, according to you, you can't isolate the problem better. Despite owning revolvers, or so you say. You could try switching ammunition but I doubt that would cause it. If both magazines are FTFing at that frequency then there is something wrong with the slide or the barrel and no amount of playing around will solve the problem.

In fact I wouldn't even call Gander Mountain. I would call Ruger directly and give them your serial number and tell them what the problems you're experiencing are. I have never heard of a 10% Failure to Feed on a new SR40 (or any other pistol, for that matter) and you might have gotten a used gun or something from Gander Mountain. My sincere advice is to put it back in the case, call Ruger customer support and send the gun back right away. Make sure you tell them who you bought it from and please do report back and tell us what happened.

In a Failure to Feed? That means the round is not just not going into the barrel, it's also being pre-ejected. If that's true, please do yourself a favor and don't attempt firing another round before you get some help. Did you run over the gun with your bulldozer?

 

[jlagesse]

No I bought it, cleaned it, loaded it, fired it.

Well, then you have a ringer. You've got a gun with a serious malfunction using both magazines and more probably deeper in the the slide and possibly barrel and you shouldn't fire another shot until you pack it up and send it back. I'm skeptical of your story but even if I wasn't I'd tell you that. I've never, ever heard of a 10% FTF on a gun like this with the ammo. you're talking about and if you're telling the truth the gun is flatly dangerous and you shouldn't fire anything else out of it. It's brand new: get Ruger to fix it, I'm sure they'd be happy to because this doesn't happen with the SR40s I've heard about. You either have bought a damaged gun or you have something that broke right away for some reason in the first couple of rounds (it's possible) and you shouldn't fire it any more until you get it fixed. A 10% FTF on this gun is not just excessive it's really unheard of.

Take the slide off and look at the lug that feeds the next round from the magazine. The only thing I can think of is that you have got a slide that is not pushing the next round into the barrel straightforwardly and that is a highly unsafe condition. It could also be that the slide itself is moving laterally. If you don't have deformed magazines and those things are not true then the barrel of your gun and its lockup with the slide are totally malformed. Please don't fire it. Send it back. Somebody sold you the worst Ruger SR40 in the world, after they ran over it with their bulldozer.

The most important thing is to be safe. I wouldn't fire more rounds out of that particular gun until you get it completely spec'd out and squared away. If it is really feeding that badly there is something seriously wrong and you should be able to see it on inspection.

Picked my sr40 up last week. Cleaned it, removed mag dc, oiled and assembled it then went on to fire 100 rounds with 0 (zero) issues. Sights seem a tad off but I could still group well enough at 20 yards...
