Shield .40- rounds get stuck chambering?

[gzimm]

If I load up a magazine to capacity, insert it fully into the pistol and either rack the slide manually, or use the slide stop to release the slide, my rounds nose up and get stuck in the chamber. I happends about 1 out of every 5-8 times. I sent the pistol back to S&W and they changed the mag release. I took it to the range and it's doing the same thing. I have a 6 round and two 7 rounders. The 6 rounder seems to work fine. I'm seriously thinking about getting rid of it. Any ideas?

Here's a round jammed in all it's glory.

I would say weak mag springs and recoil spring and possibly a feed ramp issue.

mag springs are STIFF, I have a hard time getting last round in. Maybe recoil spring.....

I would doubt that any of your springs are weak. You say loading it manually but are you following the slide forward? I always pull the slide fully to the rear and release it to give it that little bit of extra momentum it might need to force the cartridge rim up under the extractor. Think of how fast that slide is moving during the firing cycle, if it isn't jamming when firing it most likely has something to do with the slower operation when the first round is started.

My wife had the same issue. Found she was riding the slide forward, Stoped her from doing that and it took care of it.

Part ammo problem, part not using sling shot method of racking correctly. One of my M&Ps would do that with Hornady critical duty if I didn't sling shot it from all the way back, though it ran fine in the gun.... That ammo didn't inspire confidence in me, I switched to HST's and haven't had an issue.

I'll try that. That is critical defense. Though it does it with my plated Rainer reloads. I don't ride slide. Even with slide locked back and hit the slide stop it'll do it. If I hold mag all the way up its fine. S&w replaced the mag release too

I've been using Speer Gold Dots with no issues. I too have issues with that final round in the mag to the point of being worried about crimping the casing. Thankfully no feed jams with the Speers.

I only have that problem when I use cheap aguila ammo I Switch to wwb no more issues.

The gun is not designed to load, from the magazine to the chamber, by releasing the slide stop. The slide should be released from the rear-most position, as it is when firing.

Well it seems to by hornady TAP and critical defense. I cycled a few mags of Remington's golden saber without issues.

As to not using slide stop, how do you do a quick reload? Every pistol at an IDPA match is using the slide stop to release slide on a new mag.

You pull back on the slide and release it, being sure you don't follow the slide forward. A lot of times during a match inserting the mag with umph, will make the slide auto index, a.k.a, it will drop the slide for you. That is a normal polymer gun trait and a time saver during a match. As long as you don't have your finger in the trigger guard when it auto indexes, auto indexing is perfectly safe.

In general I'd recommend staying away from Hornady handgun ammo. Besides the cycling issues, terminal ballistics aren't as good as say Gold Dots, HSTs or Ranger T's.

It's funny, my FS .40 will do that but my shield wont.

The FBI has stated per test the hornady critical duty the top self defense round. Especially for 9mm. The ops issue doesn't appear to be an ammo brand issue.

Ya I use critical duty in my shield and I love it. Shot 50 rds when I first got the gun to make sure it cycled fine, and it did. No problems at all
