Century Arms dremel slide TP9SA warranty wear

Slide Scratches/Gouges – TP9SA

I’d noticed that the underside of my TP9SA’s slide has some unusual metal wear.  I couldn’t find what was causing it.  Well, someone else did:

At 1:18 and 1:22, he shows his slide’s wear…it looks very similar to mine.  He discovered that the magazine was scratching the slide!  My slide scrapes weren’t as bad as his (I’ve only shot 100 rounds through my gun).

I checked my magazines and some of the paint was missing from the very top of both…to double-check, I used a black Sharpie to coat the bare metal both of my magazines’ wear marks.  I also covered the slide’s wear in black Sharpie.  Then I placed the magazines into the gun and racked the slide maybe 10 times each.  I checked the slide and mags again.  The marker ink had rubbed off.

I used a Dremel to grind a bit of metal from where the ink had rubbed off…I removed just a tiny bit of metal with a grindstone.  I covered the ground areas with Sharpie again, then racked the slide with both mags again.  There was no more wear.  Fixed!

The guy in the video actually sent his gun back to Century Arms as a warranty claim.  He also had a trigger spring that was mangled a bit that Century Arms is going to take a look at, too.

I’m glad he posted his issue…I’d have never figured out what was causing it.

UPDATE:  I wanted to keep the readers informed on this issue.  I bought a tan TP9SA not long ago and performed the same grind of the mags that I did with my black TP9SA.  I took the tan TP9SA to the range on 4/3 and it performed flawlessly.  There are no more slide gouges.  It has minor scrapes due to dry racking while the mags were inserted…I covered them in black magic marker to determine if the scrapes would still occur and it hasn’t occurred.
