P320 Compact, waviness in the frame

Hey all, new to the site, not new to firearms. I just picked up a P320 Compact, it was built in late June this year. I have noticed several spots in the frame have bumps or waviness. These waves or bumps run vertically and are in 3 different areas, with a total of at least 6 bumps and can be felt as high spots in the polymer if running your fingers over them.

Do others notice this too? Mine are on both sides just behind the takedown lever and on the right side near the front of the frame before it tapers at the end.

Thank you

Here's a pic. Notice the lighter color marking just behind the takedown lever, it is a high spot in the polymer. There's two more up at the front under the slide serrations, they're a bit harder to see.

Here's the other side, notice the 3 stripes right at and behind the takedown lever, again high spots.

I've never seen one like that. I'd surmise it's a new method of plastic production or maybe just a new mold issue. No idea though. Likely just aesthetic issue, but worse comes to worse you drop the $50 for the new grip frame. Or send it to Sig and have them do it.

I'd say contact Sig for a free replacement grip module.

That was the plan if others did not have the same thing. Wanted to make sure these weren't just poorly finished normally.

You have waviness like that behind the takedowns lever on the P250 and P320 frames below, as well as just behind the front of the trigger guard on the SPC-2009 and SP-2022 frames below.

You can also see waviness behind the takedown levers on pictures of P250/P320 Full, Carry, and Compact grip modules in the Sig Store; the waviness is most apparent on the pictures of FDE grips, but can also be seen on some pictures of ODG grips.

Another thing to think about, if you're happy with the "medium" that comes with the gun, then I'd definitely want it replaced.

But if you were planning on downsizing (small) or upsizing (large), then I wouldn't fret about it. You can get modules for $35 dollars at a few online places.

I have two for my compact (medium and large), and neither have any blemishes.

Yup, those pictures show the same thing. That's disappointing that Sig finishes the frames that way. I have M&P, Glock, XD, (in addition to non-polymer framed guns) and none are as poorly finished. I think I'll run by the LGS and see if theirs match up to mine and the pictures, if so, I'll let it go. If not, I'll call and ask them to swap frames.

Medium is good for me, I'll check the LGS and post my findings. It's not really a big deal, just don't want a blemished gun that I paid non-blemished price for if they're not all that way.

If it is any consolation, you can't see the waviness in my avatar photo and it is not noticeable when handling the guns, but it is visible under the right lighting conditions.
