Today was the first time to really try out my 15-22 I bought in December. Out of about 100 rounds, I had probably 10 failure to fire. I broke the gun down to clean it this evening and it appears to me that the trigger group is sort of "tweaked" and isn't hitting the firing pin on center. I'm going to try to include 2 photos of what I'm talking about. Does this appear missaligned? Can you see how the wear marks are off center on the bolt to firing pin? I think the failure to fire is because the hammer is coming up strkeing the side of the bolt and not hitting the firing pin square. Send it back to S&W?

Hope my wording is right.

Make sure the retainer bolt going through holding the firing pin spring in place is seated correctly. Picture #1 on the left side of gun. I can see the pin sticking out. I don't think it's pushed through far enough.

When you look at the left and right side of the gun, the bolt should be barely recessed on both sides. If one side is sticking farther out, it's probably misaligned.

I kinda had the same thing happen to me last time I cleaned it.

Now whether that fixes the FTF issue, I don't know.

I think that was it. I didn't even notice the pin sticking out to the side (and not sticking out the other side) and you can even see the pin sticking out in the first picture. I adjusted the trigger group (not sure of correct term) and the pin that goes through the trigger and blue spring now is in the hole and it looks much more square.
I'll try it out again maybe Friday, but hopefully that's all it was.

Thanks!

That is the hammer. The pin walked part-way out of the hammer and made it "caddy whompass" in there. That's why it impacted the rear of your bolt. Pushing it back in is the right fix there, but I don't understand what made it do it in the first place. My pins always have stayed put, especially with the pressure of the springs on parts they hold in place.
 
It looks to me that in your picture one of the pins that hold the FCG has walked out. I had that problem and it produced the same results. I ended up pitting in a set of anti-walk pins.
 
Is your hammer one of the newer embossed ones? (less material on the sides/not flat)

I've never had any issues with my pins walking. AR15 trigger groups are designed to hold them in place without needing special anti-rotation pins. The rear is held by the legs of the hammer spring, and the front is held by the small clip/spring inside the hole of the hammer.

S&W changed the trigger groups (at least the hammer) they use in the 15-22 sometime in 2012. The internal hammer spring is known to break on the newer style and cause the front pin to walk. Even if yours hasn't snapped yet, I'm sure it's weak enough to let the pin walk.


I wonder what the sear and hammer contacts look like now.
 
Not an AR/M4 expert here but isn't the hammer pin retained from walking by the legs on the spring fitting into shallow grooves in the pin? If yes and the spring is of reasonable strength, the pin should not be walking, I would think.

The hammer and trigger pins are mil-spec, but the lower receiver on the 15-22 is slightly larger so it can not be coupled with an AR 15 upper.

The hammer pin is usually the one that walks out because its not retained internally as well as the trigger pin.

The hammer pin is held in place by a straight spring that's fitted into the hole of the hammer, the trigger pin is the one held in place by the legs of the hammer spring.
In this pic you can see the retainer spring in the forward part of the hole, it's the part that's weak on the newer 15-22s and lets the pin walk out.

So is this something S&W should warantee fix? Should I send the gun in to S&W?

Good going bbbb. :D Some of those pins do like to walk in some models. That's another reason I clean after shooting,good time to spot any potential problems.

Ammo problem "could" be solved too. But it could also be the ammo. Some 22 aren't what they use to be.

I would think they'd fix it no problem.
After returning my first 15-22 for this issue, and getting a new one in return with the same trouble, I just replaced the hammer with a real AR hammer and never had a problem again.
Probably voided my warranty, but at that point I just didn't care anymore.
 
So, S&W worked out the kinks they had when they first released the 15-22 (mine had them, had to go back home several times), and then they go and change things which introduces new problems?
Was S&W recently bought by Glock ?
