If it is only with one magazine, I think you have already solved your problem...

The little red projection sticking up on the back side of the upper portion of the magazine is the part that causes the bolt to stay open. I would look closely at this part of your magazine that causes you problems. It could be slightly shorter, or bent is some way that does not allow it to move the lever that actually holds the bolt back.

If the magazine is not the problem then you should look closely at the lever in the lower receiver that gets pushed by the magazine and see if your problem is there.

The last place to look would be on the actual bolt itself. Look there if everything else seems to be working properly.

If these are all factory branded parts and the gun is new (things that you have represented to be the case) then contact Smith & Wesson for replacement instructions. Look in your owners manual or on their web site for contact information. This should be resolved pretty easily.

This is a not uncommon problem. It comes from a combination of two things: a too-strong spring in the bolt latch and a too-weak spring in the 25-round magazine. The solution has been known for several years, now.

Drift out the pin holding the bolt latch paddle and cut two turns off the bolt latch spring, then reassemble. Problem solved forever.

It also helps to put a single drop of CLP or other cleaner/lubricant on the bolt latch pivot point.

No need to send anything back to S&W.

yeah right

at around $65 a mag here in england,i need a fix

keith

thanks guys i will take a look at your suggestions

I would think that this would happen with all of his magazines if the bolt catch spring was too strong. Before I cut any springs, I would be looking at that magazine, particularly the follower and the tab that comes off the back. Make sure that the follower returns to the top most position when the mag is empty, that it isn't getting hung up...

If it were all the magazines, then I would be looking more at the bolt and bolt catch.


Horses before zebras.

Do retailers not do returns in England? Here in the US, I would take it back to the shop and exchange it for another.

Suit yourself. You asked and I gave you the fix that has been pretty much standard for the last three or four years.

I didn't ask, that fellow in England did. My rifle and magazines work just fine from the factory...

Agree. I had intermittent issues with the bolt not staying open... especially with subsonic ammo (which I mainly shoot). After cutting off 2 turns, my bolt stays open 100% of the time now.

Trebor, I just read some of the bolt won't hold open threads and one person had the same issue as you... bolt hold open failing with one particular magazine. They said they "rotated the spring"... not sure if that means they flipped the spring in the magazine, or just turned it 180 degrees. They said that solved their problem with the single mag.

how strange i will check over everything and if all else fails,i will remove 2 links on the spring,thanks guys for all the imput

My mistake, oops!

Mine did this through the first few hundred rounds.

I *gently* polished the rails the bolt carrier runs on with 1000-grit sandpaper to smooth out some obvious roughnesses in the stamping, and the problem went away.

Probably a combination of wear-in on the mags and gun, and that polishing, letting the bolt more efficiently blow back, giving the magazine protrusion more chance to rise up and trip the catch before the bolt comes forward.

This is THE fix I came up with years ago and shared on the forum. The risk is a $2.00 part that is readily available in case you mess something up.

It is probably a $5.00 part in England.

HaHa you won't be far off

but who sells the spare bits here....we can get the rifle,but not

much else

I have 2 shops there and will soon have a third. They should be able to get whatever you want.

I recently purchased two 10 round mags, one worked fine the other would not leave bolt open, I noticed that the organge follower was upside down, installed wrong from the factory, took apart reversed follower works fine, bolt stays open, hope this helps.

D'oh (Think Homer J Simpson)

I noticed today that all 6 magazines I used (all S&W 25 round) would not hold the bolt back after the last round. Odd thing is, they all worked fine before today. Shooting Mini Mags and Win M-22 so decent ammo was used.

The only changes - installing a set of JP Yellow Springs, and gently radiusing the catch on the charging handle and clipping the spring to reduce tension (Rainier Arms Handle - thread here charging handle question - describing issue of wearing away the stop on the upper.)

Anyway, I would not think either of those two mods would affect the bolt holding back, but since those are the only two things different from last time and today, I could be wrong I guess...

The springs, didn't really notice a big difference on the trigger anyway, so probably will pull them back out in put the stock ones back in. I can put the stock charging handle back on as well, try to figure out what the deal is.

Oh, also, it works fine when manually cycling the bolt on an empty mag, just fails when actually firing...strange.
