Not good!
Get out the Hoppes. You've got gun weevils.

 

[fxdc]

This is how I got it new.
Not sure how hoppes is gonna help.
LOL

Will have to change progression of the slot spacing and maybe width to remove or miss them.
When I do the cutting.

Not sure it will work on cheese graders?

 

[fxdc]

Ya can rack the slide on the BG's face.
LOL

Just a guess how about retaining lubricant? It also could be how the CNC
machine tool clamps on to the slide when it was manufactured?

Is that a 2.0? I've never noticed those before, but now I'm curious and want to go home and look.

Is that an M&P 2.0?

I have more, I'm special (Don't say it)....This is a 40c old model. Maybe they have a blind guy on the assembly line and this is for him to identify the part.........

Who the heck programs this?

I saw something about this on the S&W forum a while back. Apparently those dots, which will be found in different configurations on different guns, is a way they use to identify the milling machine and/or the contractor that milled the slides. Pictures of the different configurations can be found on the internet. Either way, it's intentional on S&W's part. Someone also mentioned seeing something similar on Glocks, starting with Gen 4.

Just got off the ph with CS at S&W.....

And it's part if the MFG process.and has never caused an issue with the end product.

So it's straight from the mfg.

 

[fxdc]

Going to proceed with cutting my slide as it won't be seen from the outside.

Will post pics after I'm done.
