Hey all! just wondering if any 2.0 owners have taken your strikers out to find that the new pink striker channel liner is actually loose in the channel?? when I say loose, I mean that it is able to freely slide back and forth in the channel.

I was under the impression from various sources that striker channels were supposed to be kind of tight. Not so tight that you have to have an arbor press to install them but tight enough that they don't move. All my older M&P's with the white striker channels are in pretty firm and all my glocks as well.

My 5" FDE 2.0 9mm had this "loose" channel liner right out of the box so I just called today to send it in and have it redone. Then to my suprise I just picked up a black 4.25" 9mm and its the same way.

I had called S&W about it when I first discovered it on my FDE and they said that "they're usually pressed in but if its not causing any problems then its ok". Well, I do get light strikes when I use NATO ammo and I'm wondering if this could have anything to do with that?

It seems to me that if the channel liner is moving along with the striker, that it could slow down the the inertia of the striker causing light strikes. Or if the liner is moving it could potentially bind up ever so slightly.

what do you guys think?? anyone have this issue or any experience with this kind of thing on another platform? Thanks!!

The 1.0 liners weren't all that tight, they did have tabs that locked them in place, once those tabs are released, the liner came out easily (I change them as part of maintenance when powder residue gets embedded into the plastic), don't have a 2.0 so I don't know if they eliminated the tabs, or changed the design of the slide so there's no place for the tabs, but suspect they figured out that it made no difference so they simplified production when they changed over to the 2.0. If you're not having light strikes, just shoot it until you are.

Pink liners?? It's a commie plot

No tabs on the new ones. They actually have a series of shallow channels cut inside now to help them function if debris or water gets in their. Kinda like how glock has the maritime spring cups for their strikers but in this case it's actually in the liner. It seems to be a clever design

Anyway, I do have quite a few light strikes when I use NATO ammo that I don't seem to get with my glocks. I do know that the factory glock striker spring is 5.5lbs vs the M&P is a 5lb and the M&P also has the striker return spring that actually could slightly slow down the striker and the end of the stroke but I'm not sure if that's enough to light strike NATO stuff or not. Maybe the NATO spec stuff has harder primers? Two different brands I've tried of the NATO stuff has had the same result.

And yes...PINK!!!!

NATO 9mm has harder primers (think CCI #41's) they have to be designed to be used in sub guns which are blowback, open bolt designs. I have a couple of NATO rounds with 3 dents in the primer and they still didn't go off. They work great in a Beretta M9 and most Steel frame guns, but not so much with a M&P, there are other (stronger) springs available for the M&P but I don't shoot them anymore in competition so I quit fooling around with them.

That might be the whole problem. I may just have to get some extra power Striker Springs if I want to shoot the NATO ammo. When I do get a Light Strike, it will usually go off if I hit it a second time, and I don't think I really have any problems with any other good quality ammunition. Also I need to shoot some more of the NATO stuff with my 1.0's too see if those light strike it too... I don't remember if I've shot NATO with my original 9mm or not

I just wanted to see if anybody else had the issue with the floating Striker Channel liner to see if it seems normal.
