Help with a malfunction on a S&W 6906

[brin747]

I took my new (to me) 6906 to the range this morning for some quality time. I put about 200 rounds of Blazer Brass 9mm through it and really like the accuracy and function. However, it did jam on me twice and I'm curious about it.

I don't think I limp wristed it, it didn't stovepipe or jam on the ejected casing. What happened is that the slide basically didn't come all the way forward, almost as if I had racked the slide and held it on the return so it didn't have enough energy to lock forward.

I did clean and oil it when I got it and lightly greased the slide. Any thoughts on how to resolve this or do I need to have a gunsmith check it?


Thanks for any help.

Sounds like you need a new recoil spring. If the 6906 was purchased used, changing out the recoil spring is always a recommended procedure. Good luck!

I would try different ammo first. Sounds kinda like it doesn't quite care for the Blazers case.

New recoil spring?

It's probably the recoil spring, but oil the barrel near the muzzle as well as the top of the chamber. Look for the wear marks and put a drop or two of oil there.

agreed, i'd try a new recoil spring first.

Is the recoil spring a gunsmith thing or can it be DIY? I do not have experience working on firearms.

 

[Joshu]

If you can clean your firearm you will be able to replace the recoil spring.

Thanks for all the help guys.

Forgive the stupid question, but is the recoil spring the one that covers the guide rod?

 

[Joshu]

Yes.

Part # 51

When you strip it to clean, you would just reassemble it wiith the new one. Make sure you order the right part. Brownell's site is often more confusing than Midway. Not a bad idea to check them both actually.

Oh, okay, of course I know how to replace that. Thanks for saving me a trip to the gunsmith!

You have a great gun. Just needs a little adjustment.

 

[brin747]

Thanks Ed, I truly do like it. It fits my hand like a glove and points very well. I put about all 200 rounds in the 10 ring at 7 and 15 yards.

 

[Joshu]

brin747, sounds like you found a perfect fit.

I have a tendency to consider only the slide/reciever, frame (on a pistol), and the barrel as the "gun". Anything else is fair game to be replaced, and in fact the barrel better mind its manners too. I know we pay good alot for our firearms, and we should expect them to be perfect out of the box, but I'm not sure if that ever was the case, even in the good old days.

Joshu, this was a used gun but it's in pretty good shape. I got it locally for $450 with 3 factory 12 round mags, which was fair from what I saw on Gunbroker.

One I have the bugs ironed out and am confident it will supplement my 642 as a CCW when I am wearing heavier clothing.

I actually enjoy taking my "toys" apart and learning how they work while fixing them...
