So Ive had my 9ve for a cpl weeks now, but I finally got it out to the range for the first time today. It got jammed after every single shot. I cleaned it last night before I took it out today. My question is what might be causing this? Its like the bullets arent getting feed all the way into the gun or something. I dont think its the mag, because I tried both of them that came with it and its the same. Any help with this problem is greatly apreciated.

What type of ammo? maybe try something else until it gets worked in. There not reloads are they?

Is the any Burs on the feed ramp?

I ran into this problem a few weeks ago. You might be doing what they call Limp Wristing. I corrected the problem, and cleaned my mags just incase.

Limp wristing is a term used to describe a phenomenon commonly encountered by semiautomatic pistol shooters, where the shooter's grip is not firm enough to hold the frame of the pistol steady while the bolt or slide of the pistol cycles. This condition often results in a failure to complete the operating cycle, properly termed a malfunction, but commonly (and incorrectly) termed a jam. Rifles and shotguns, if fired without the stock in the shoulder, may also be prone to limp wristing. Of the important variables involved in this type of jam, bullet and gas momentum, slide and barrel mass, recoil spring pre load and spring rate, and shooting hand and arm mass are much more important than the compliance [limpness] of the wrist.

No there not reloads, its Federal ammo. Ill look into the limp wristing thing. Hopefully its something easy to fix as that.

Not sure how many rounds you have through your Sigma, but you might want to take down the Mags and clean them. Did you buy it new or used? I cleaned my mags to eliminate that was a problem.

I bought it new from Buds. After seeing this video the limp wristing is looking more like the possible problem.

When I first started shooting the Glock 21 (pd issued) I had the same problem. I had shot revolvers for so long it never occurred to me. Gave me some awful fits til I figured it out.

If it is that common it is more than likely limp wristing. The problem for new shooters is they have seen too many movies with actors using their arms to absorb recoil by bending their arms. Semi automatic handguns require a semi firm grip for the gun to cycle and reload properly.

If it isn't limp wristing, can't hurt to polish the feed ramp. Get a pack of assorted fine sand paper. Start with piece of 400 wrapped around a pencil eraser to polish up and down the feed ramp. Do the whole width of the feed ramp, not just the middle. I use WD40 for lube. After that, clean and move on to 1000. I stop there but hitting it with even finer paper will polish it out more. Some use a dremel, I prefer to do it manually.

His pistol is 2 weeks old. He shouldn't have to do any work on it. At most send it back to S&W.

I've tried to get every auto I've shot to limp wrist and never had. I must be made of stone.

I've seen plenty of pistols that had machining marks on the feed ramp. My P-3AT was particularly bad, wouldn't feed FMJs when hand cycling. I did the feed ramp before I even took it to the range. Not one fail to feed. If he wants to send it back to S&W that's up to him, but polishing the feed ramp is also an option for him to consider.

Im going to try and fix it myself anyway I can before sending it to S&W. On all the jams only 1 was a stove pipe, all the rest was failure to feed. Does that sound consistant with limp wristing?

From what I understand, yes it does.

I wouldn't recommend using WD40 for lube - even if just for polishing the feed ramp - on any gun. It does more harm then good.

You might try a different type of ammo just to be sure. I wouldn't go messing with it myself. LSG has a short turn around for delivery. Call them the number should be in your owners manual. It won't cost you a dime. I don't subscribe to the limp wrist theory and don't want to get into it. I don't have this problem and haven't been able to duplicate it with any of my handguns no matter how loosely I hold them.

My wife has the same issue with the SD9, it is a limp wristing issue. I can literally see it while she is shooting and can predict it to a t. I have never had an issue while shooting it. Go buy a cheap wrist splint from the pharmacy and you will see it disappear. or if you are a bowler you could try that. The only way to really improve it naturally is to practice. If it still continues try getting some one on one training.

It's also funny because shooting the .40 she had no issues, I think it's because the greater force allowing for more forward motion.

Really, how? I've used WD40 on all sorts of metals, even when machining sometimes on a mill or lathe. It's my favorite for polishing something on a lathe with ultrafine for a nice finish. Never once seen it cause damage to any metal, either low carbon steel, or tool steels.

My solution would be to have a different and experienced shooter fire it before doing anything. If that shooter has problems THEN start in on the solutions being offered including sending it to Smith. Just thinking out loud here...

I don’t use WD 40 for anything but general garage stuff with the exception of door hinges, but, I have a friend who uses it on everything. He even cleans the crud out of his brass tumbler with it. He shoots a few hundred rounds a month and uses it to clean his guns too. I think only the powder crud on the outside but I can’t imagine it could be doing any damage and him not know it. He is very particular with his guns.

I used to work in a machine shop and we used to spray it on the product right after cutting or grinding to stop rust. We used all kinds of steel, cold rolled, stainless, tool steel whatever. D2 was the worst for cutting, harder than @%&* even before it got heat treated.

To the OP, try shooting with a firmer hold or have someone else shoot it to make sure it isn't 'limp wristing'. I have a Sigma, my wife, both daughters and my son have shot it, no problems, if that doesn't clear it up, I would send it right to S&W, it IS a brand new piece, don't screw with it.
As far as not using WD40, puuuulleaze, I've been using the stuff on a wide variety of things for near 40 years, cars, boats, motorcycles, electrical, and yes guns, it's a great way to polish, keeps the paper/stone from loading up.

The only possible way that WD40 could contribute to any sort of damage would be that it would tend to attract grit and gunpowder residue. If you let that build up to the point where it is causing problems then you aren't maintaining your firearms properly.

Before you call S&W, suggest you let a couple other shooters try your gun with your cartridges. Federal ammo is good quality stuff, so that should not be a problem. If it is a limp-wristing problem, letting other experienced shooters see what they can do with your gun and ammo should tell you quite a lot.

Do not monkey with the gun. If it is a new gun and needs any sort of repair, S&W should be the ones that do that. Make sure it is cleaned and correctly assembled, and that is all. Leave the rest to the experts - the guys who made your gun.

WD40 will harm finishes and is a penetration oil, not a lubricant.

C' mon, we're only talking about using WD-40 as a lubricant for polishing the feed ramp, not sousing the whole gun indefinitely.

WD-40 is basically a solvent/vehicle like kerosene, witha bit of parafine added to form a protective coating when the kerosene evaporates.

But if you are polishing the feed ramp, use a longitudinal stroke (in the same direction the cartridge is moving when chambering), and when you have achieved a good polish and have removed the rotary tool-marks, quit - and then wash all the swarf out with solvent like Hoppes. No way will it attract crud, then.

Then, if it fails to function properly - THEN look into limp-wristing.

I assume you lubed after you cleaned it. Just a thought: Sigmas run best when nearly dry. Clean it thoroughly; Lube it sparingly just as the manual states; it is very easy to over lube the Sigma-- and some do not run well. Seriously, some Sigmas just will not run well if lubed like other semi autos.

My Sigma wasn't ejecting properly every 10 rounds or so. I tried different ammo; I tried holding the thing as rigidly as possible. Finally I called S&W and sent it to them. They fixed it and I haven't had a single failure-to-eject since. Give them a call.

Only problem I have with WD-40 is it kills primers quickly. Keep it away from ammo.

Ejecting the used brass isnt the problem. Its feeding the next round in thats the problem.

I had that problem with a brand new MP 40 back when they first came out. I sent it back! It came back to me in five days, with a nice shiny feed ramp, never happed again. That said I would also let someone else give it shot. I frequent a busy range, and see many people who use the cup and saucer style grip, I will assume you are not one of those folks

I recently bought my second Sigma 9 m/m and the first box of ammo jammed almost every round, I was using Remington SP and was told it works in some guns and others not. Went over to Walmart bought 100 rounds of Winchester white box and fired the whole box without a problem.

Then tried some Remington SP again and it worked fine. I believe the recoil spring is stiff and just needs to be used. I would get a box of +P ammo and run it through the pistol before I would send it back to S&W, see if that works first.

Regards

I've used the Remington 9mm 115 Gr Mega pack, and Federal 9mm as well. Both bought at Walmart. No problems.
