Just joined the forum and have been reading for the last hour. Great group here! I purchased and SD9VE a little over a week ago. Cleaned and lubricated it and headed to the range. First magazine was flawless. The next 4 mags I went through the slide failed to lock back after the last round. This is with Monarch 115 gr ammo. Came home and cleaned and oiled again. Went to the ranch yesterday and put about 50 rounds through it. Had 3 rounds that failed to eject and the slide failed to lock back all 3 times. Thoughts? I'd really like to avoid sending it back to S&W but will if y'all think it's a manufacturing issue. The Monarch ammo is cheap, but I don't feel that I should be having this many issues. Thanks for the help guys.

Or it could be another SD9VE has a problem. I would definitely try another ammo. Monarch is about as bad as it gets.
 
Welcome to the forum!

I'd suggest these things:

1) Clean (but don't lube) your magazines, load them to capacity, and let them sit for about a week.

2) Lock your slide open, chamber empty, and let it sit for about a week, while the mags are sitting.

3) Buy some better ammo, and several different brands. (May be tough to do these days, but try what you can find...and use FMJ rounds at first, before your defensive rounds.)

4) If you know an experienced shooter, ask them to shoot your gun as well.

You don't say if this is your first gun, or what your shooting experience is. You may be limp-wristing it...you may have a gun that is ammo-sensitive...and/or it may just need a break-in period (locking the pistol open and loading the mags helps) although that's not usually the case in these guns. The steps listed above introduces several variables at once, which usually isn't what you want to do when trouble-shooting, but I think you will find that your problem is either limp-wristing or ammo-related, so steps 1 & 2 probably won't help or hurt in your case...but they are what I do with every new gun I buy.
 
I'm a fairly experienced shooter and limp wristing isn't the issue. I figured it might be the ammo but unfortunately that's all they had at the store. I've put thousands of rounds of Monarch through my Glock and never had a problem. I'll try some different ammo when I can get ahold of some. Thanks for the suggestions.
 
I put about 500rds of monarch through my sd9ve without an issue. In fact, no issue with any ammo as of yet. I just thought I would contribute that.
 
Something I read, but can't find right now...load your mags with three rounds, and see if the slide locks open. Then 4, and then 5, and so on...to see if there is a point where the problems begin with a certain number of rounds in the magazines. Also, note if this occurs with ALL magazines, or only one of them.

Also, I assume you bought the gun new? If not, do you know the round count? Seems unlikely, but maybe the recoil spring is the culprit.
 
I find the Slide lock lever rides right next to my thumb and if i do not make a conscious effort to keep my thumb away it causes issues with the function of that lever. Either locking the slide open when ammo is still in the mag or not locking open on the last round.

Is it possible you are riding the lever and not allowing it to move up?
 
EBK, I saw that you posted that somewhere else on the forum. At least I think it was you. I checked my grip before I posted thinking this was a possibility. Unfortunately that wasn't it. Hopefully I can find some decent ammo soon and see if I can figure out what's happening. Thanks again for all of the suggestions.
 
It sounds like you have about 100 rounds through the pistol? I have to admit my SD9VE has NEVER bobbled with any ammo HOWEVER there are more than a few manufacturers of pistols that cost WAAAAY more than your SD9 that recommend running alot more rounds than that through them before its "broken in".

In fact some manufacturers wouldn't accept a pistol for return until alot more ammo than that has been run through them. They'd say keep shooting it some more and THEN we'll talk about it!

I've fired a fair amount of Monarch through mine without a hitch but I have to admit I do some "cleanup" on all of my pistols before I fire them, even for the first time.

I'm guessing you have a nice, tight SD9 that'll take a few rounds through it to loosen it up a bit.

Sounds like K(m)imber! :p

If you have a problem with one of their guns, the first question they ask is, "How many rounds have you fired?" If you answer less than 500, they will tell you to shoot 500 rounds and then call them. If you still have a problem after 500 rounds, they will tell you that it's your ammo or grip, and to try again.

That's why I no longer own the three Kimber 1911s I once had...and will never have another.

I hope this ends up being the problem. Was out at the ranch again today and shot, but very little. Still the same ammo because I didn't have time to get by the shop. Two mags, no ejection issues, but the slide didn't lock back either time. I've now put about 150 rounds through it and only had the slide lock back on the very first magazine. I've tried full mags, one bullet, two bullets, three bullets......
 
I am very positive it is the ammunition.

About 3 months ago, I took an officer to qualify with his SD9VE. He had bought a box of Monarch 115 FMJ from Academy. First ten rounds are double taps from the waist one handed after drawing from the holster. It jammed on all rounds. I then loaded another magazine and fired all 16 two handed weaver and not one jam. I then tried it at the hip side. Jam and jam.
I pulled out some Winchester White box 115 grain FMJ and repeated the side hip from the holster. NO jams.
I tried the replicate it with a Glock 19 using the Monarch. Could not get the Glock to jam. Tried it again with the SD9VE and Monarch. Jam.
We started again and used all Winchester. No problems at all for the next 150 rounds.

I have had problems with Monarch in the past. Ruger P-95 and German P38 will not cycle Monarch 100%. Recoil springs too strong.

Found that some rounds of Monarch will not penetrate a 2X4 at times. Winchester, Federal, Remington all run my guns perfect. The only reason I use Monarch is because at times it is all I can find. In a normal combat two handed hold, it does fine thru Glocks, SD9VEs and SW9VE.
 
Take a close look at the magazine followers. With an empty mag in the gun, push the slide back slowly. How well does the follower contact the slide stop? Does the magazine spring have enough tension to push the lock up? Does the gun seem to bind just before the moment of lock?
 
pull the slide off, insert empty magazine, and take a look at it. does the magazine follower contact the slide stop properly. it might need a slight adjustment.

Yeah, that's the primary manuf I was referring to although others do that as well (Kahr). ;-)
