This is nuthin new but Shield owners should fix this problem before it causes malfunctions and prevents you from removing your slide...

All Shield 9mm & 40 frames have this same problem where the slide lock spring can work its way out of its retaining groove in the left side of the locking block just above the disassembly lever.
When the spring does pop out (usually after firing 50-300 rounds), you won't be able to remove the slide when you try to field strip or clean your Shield because the end of the spring will catch on the inside of the slide. Worse, when this spring pops out while you're shooting, it will cause enough friction or drag on the slide so that your Shield will stovepipe and mis-feed because it can't fully cycle to eject properly and it will also fail to return to full battery (close all the way on a loaded round) because of this spring being jammed inside the slide.

When you try to field strip the gun, the spring stops you dead because it's caught on the underside of the slide preventing it from moving forward off the frame. So, what do you do?

Here's the fix:
1) If your slide is already stuck because the spring has popped out of it's groove, don't force the slide! Instead, move the slide back about an eighth of an inch so you can see the spring out of it's groove and insert a small bladed screwdriver and pry the spring DOWNWARD so the slide can come forward off the frame.
2) After you get the slide off, if the spring is not bent out of shape then you can use a small bladed screwdriver and a punch to force the spring back into the groove. You'll need three hands here so be prepared!
3) Once the spring is back into its groove, use a 1/16" punch and a small hammer to tap it fully into its groove so it's COMPLETELY recessed along its entire length.

Go shoot your Shield some more and keep an eye on the spring. If it begins to walk out of the groove again, send the gun back to the factory for a permanent repair. Otherwise, you'll be ok.

Important: Even if your Shield has never had this problem, you should definitely perform Step 3) on it as a preventative measure. I bought 13 Shields and have done Step 3) on all of them. Every 9mm & 40 Shield I have needed to have the slide lock spring tapped fully into the groove, even those that were never fired yet! The springs in the Shields that were fired more than 100 rounds had already worked far enough out of the groove to show wear spots from rubbing on the slide.

The 45's have a much DEEPER groove. When the spring was tapped with the punch, it recedes considerably deeper into the groove than any of the 9mm & 40's do. But, when the spring is fully seated on the 9mm & 40's, it is at least flush with the side of the locking block and not sticking out of the groove anywhere along its length. Obviously, the factory is not fully seating these springs during production or this wouldn't be necessary.

Remember, use a 1/16" pin punch and a very light hammer to tap the spring back into its groove BEFORE it pops out, which many eventually will.

I'll try to figure out how to post a picture later...

Thanks to member BigWheelZip whose picture I just stole...:eek:

Let's see. . .this sounds like why I don't and never will carry a Shield. No need for anybody to say, "I've never had a problem with mine." I will not carry any handgun that isn't proven to be 100% reliable. Those guns can sit in my collection. . .not in my pocket or on my belt. My carry gun is a M10 or M64 RB snub.
 
U forgot about the mag spring issues :eek: on all of them since day 1, S&W tried to fix this but still happ and I got Wolff springs for all of mine and the 1's for the rebate if it ever gets here!
 
I've been known to get carried away when I see great value in a gun, like I did when the $75 rebate was on and I got discounted LEO prices as well. :D
 
The Shield is an awesome weapon...... thats why they have sold so MANY and continue to sell so many

I have never heard of this issue, and have put many more rounds down the pipe than listed above


I dont think its going to keep me up at night

well for what it's worth, my Shield (PC9) has well over 1k rounds with 0 troubles. No slide issues, no mag spring issues, no ammo issues.

I view it like a Camry or Accord. They sell a million and most are rock solid. But a few will have things pop up to repair. Not sure if anything mechanical can be 100% perfect for every single unit sold.

Not being snarky, just noting that while there are those who have had legit issues there are plenty who have not.

That said, the pointers listed are good for any of us who have had this trouble or who could down the road.... so thanks for posting
 
I should clarify my above posts...
Most Shield slide lock springs NEVER pop all the way out of their grooves.
My intent was to post a fix for a POSSIBLE problem that crops up from time-to-time. NONE of my Shields has popped a spring...YET.
But, I feel more confident that they won't now that I fully set their springs all the way into their grooves.
Best Regards.

Check several posts in this forum... Search "Slide Stuck" & "Slide Lock", etc.
 
I've got over 600 rounds downrange and have never heard of this issue. It has eaten everything I have given it with zero issues except the mags are extremely hard to load and Uplula took care of that issue.



and I did buy a pinkie extension for the seven round mag. Also a great product.

Not saying it is not an issue just saying I've never experienced anything close to it.
 
I just checked my 9mm Shield for this 'problem'. The spring was not quite flush so I tapped it flush. I don't think it will be a problem, but I will check it after every shooting session.

While I share most people's confidence in revolvers, be aware that even little-known springs in them can go bad. Several years ago, a torsion spring broke in my M49. This is a spring most people don't even know about, let alone check!

1000 perfect rounds through my 9mm Shield. I guess I should throw it in the trash and buy a Glock before it’s too late. :D

Or maybe I’ll trade it for a Keltec.

Here is one picture showing a spring that slipped out, and a pair of them that shows a correctly seated spring and one sitting outside the slot.

FWIW, from what I have observed on this forum, Shield 9mm's manufactured in 2017 seem to be the ones exhibiting this issue. Earlier ones seemed more likely to have recoil spring problems.

Here's mine and it doesn't appear totally flush. I tried to tap it down further but it wouldn't go any further. Certainly doesnt seem to go flush at all. How hard are you tapping it? If I tapped one end in the other end would come out ?

First of all, every gun is 100% reliable...until it isn't.

To the OP, I have noticed the issue on mine. When I took it apart to install an Apex trigger that spring did not want to stay in. It kept popping out of its groove. I tried to tap it there good and haven't had a problem since, but I need to check it because it has been 400 rounds or so ago. Thanks

One of my 40's was just like yours. Your spring is showing wear on its end because it's sticking out. Start reseating the spring by tapping in the center near the little ripple and work outward from there to the end and to where it disappears into the frame. Just tap the punch like you were tapping a picture hook into drywall... not too hard. Use a 1/16" pin punch. Your spring will seat flush when you do it right. Good luck.

Actually that wear is where I tapped it with a punch and may have flattened the end a little.:(
