Help with new M and P shield issue

Mine is the standard model so I think it is happening with both. I don't think shooting it would hurt anything but if it is getting stuck back as hard as mine was I doubt it helps much either. I'd be afraid to take any sandpaper to a new gun. If it ends up going back to S and W wouldn't they say you had "modified" it?

Too much "paranoia" about what S&W will say about mods made by the owner. I sent mine in with Cerakote and polished striker block, etc. They replaced the striker sleeve, centered the rear sight, sent it back in 10 days at no charge. No comments, no issues.

There is some confusion about what a MFG does not want to see. Modifications to the trigger mechanism, ie: sear, safety, etc. is what they really care about. Liability issue. That being said, they USUALLY will return those items back to OEM to address that liability.

Cursory mods are no big deal.
 
If you look at the top of the area where the barrel tilts up into the slide do you see any silver areas? If so, it's binding. Just take a bit of sand paper and smooth it out. heavier loads drive the spring back further and it binds up the works. Next time try depressing the barrel and see if it releases. Polishing your barrel might also work and gives it that custom look.

Exactly. Just got a new Shield 9 in yesterday. Even the barrel is "blued". I will suggest to the new owner they polish the barrel. Agreed, looks better, may run better. Only a couple of .001" thickness can cause issues. Should you sand and polish, you are only dealing with these small dimensions. Certainly not causing any issues with functionality. Just don't get carried away, take a little off at a time. Don't be afraid to JUDICIOUSLY clean it up. After all, it's a $300 gun, (or less) not $3000.....:D

Well it's back. Can't tell what they did to it. Hope they did something besides shoot it a couple of times and decide there was nothing wrong with it. No time for a range trip today so maybe soon.
