New pistol jamming

fbodkin1 · Aug 30, 2023

Ok, I hope this is just a stupid problem. I am a new S&W owner. Always owned Glocks. I am experiencing problems with my new Shield Plus Super Carry. Got the pistol yesterday. I took it home and cleaned it. Loaded it with dummy rounds and cycled by hand. It is jamming and failing to properly eject almost every time.
I'll be hitting the range tomorrow to test my theory that I am simply not racking the pistol with enough pressure to properly cycle rounds. I have never had this issue with Glock, Beretta, Taurus or any other pistol I have owned. Im sitting here waiting out a hurricane so I cant do anything about it at the moment but post on a forum and see what other people think.
Thanks a lot for not flaming me to death.

Welcome to the Forum. Great deal of knowledge here so hopefully we can work through this.

If I understand your post you are just loading and running dummy rounds through it at home?

I would not get overly concerned until you put live rounds through it at the range. I have a couple of Generation 1 Shields and if I recall they were a bit tight when new. It may just need some work in time and the force of the round as it fires cycling that slide will be much different than you doing it by hand.

Hopefully it is nothing more than that but once you get it out to the range let us know what it is doing and then go from there.

Hopefully the storm passed with no damage for you.

To add to the above post it's good to remember that semiautomatic firearms were designed around the extraction and high speed ejection of -EMPTY- cartridge cases and while most of them don't choke on fully loaded (or dummy) rounds, some guns do not care for them when it comes to ejecting and clearing the pistol.

Indeed, give this pistol lots of live fire to determine if it works.

I have a 1.0 Shield 9. I has the stiffest recoil spring of any of the eight semi-autos I own. Unless you're racking it really, really, hard, you can expect what you've experienced. You may get some more of that at the range if you use weak 115g target ammo. Shields need to be broken in with the most potent rounds you can find. My favorite target ammo is Winchester NATO 124g. It's about the stoutest target ammo there is, and it's not particularly expensive. It is also the most accurate ammo, by far, I shoot with my Shield 9. Be sure to shoot some self-defense ammo, too. You need to be sure that it cycles properly in your new Shield.

Shoot it and get back to us.

I believe the OP's Shield is the .30 Super Carry version. Would be difficult to get 9mmP to work in it.

Oops, you're right, I missed that. So the OP should forget the Win NATO rounds, but should still shoot the stoutest ammo available for break in. S&W recommends Federal HST 100g 30 Super Carry rounds, so that's a round to start with.

Dummy rounds prove nothing, nor do they disprove anything. Run a few boxes of real ammo through that gun.

Hope you made it through the storm without problems.

Would make sure the gun is well-lubricated for the range, it may help with the break-in.

I would not read too much into cycling issues with dummy rounds. Live fire will prove if it is a reliable pistol or one that needs to go back for warranty service.

When I roll my new lawnmower around the yard without starting the motor, it doesn't cut the grass. Should I put gas in it, or send it back to Toro?

Load your gun and shoot it.

There are some guns that have to be shot with live ammo to work properly. I never had the issues you are describing with a S&W but have never made dummy rounds to check

Right after I bought a Sig P365 XL someone asked what the trigger reset was like. If I dry fired the gun and held the trigger I could not rack the slide, it wouldn't budge. The regular P365 I had did not have the same problem. I was pretty sure I had a defective gun that would only fire one shot.

But when I took the XL to the range it worked fine, the gun has never jammed and after several hundred rounds I can now rack the slide while holding the trigger although it takes a lot more force than usual.

Do they even make dummy rounds or snap caps for 30 Super Carry? If these are home grown dummy rounds, there might be a cartridge dimension issue.

The hurricane must have eaten the OP, all joking aside hope all is well.

Guess he went back to his glucks .

Really?

“I loaded up a full mag of dummy rounds and went to the range but the dang thing failed to fire every time I pulled the trigger!"

I agree that shooting the gun ought to be next on the agenda before worrying too much, but a pistol OUGHT to be able to eject a loaded round - in the (unlikely) event of a dud round at a bad time, wouldn't you want to be able to eject it and feed the next round from the magazine manually?

I've never had a problem when working dummy rounds / snap caps through a new gun at home - it's one of my "pre-range" tests after initial stripdown, cleaning, and lubing.

You don't 'dry mow' ....

Load your gun and shoot it.

....your mower before starting it?

My regret is that I could only give this 1 like. Here is 100 X more.

So what happened when the pistol was fired with real ammunition?
