TFO Sights for the P320 (#6 or #8)
Has anyone come across any TFO Sights for the P320?
I found some for Sigs but they appear to be for the P2## series and not the P320.

Edited:
I just found some on Sigs web site.

Does the P320 take the #6 or #8?

The P320 uses the same style sights as the traditional P-Series Sigs. It's just a matter of figuring out the correct height.

Some P320s have #8 front and #8 rear, while others have #6 front and #8 rear.

Look on your existing P320's sights. There should be very small numerals marked on the front and rear sights. Match those to the equivalent height P-Series TFOs.

No, you can NOT use regular TFO sights on a P320. You have to order a Sig cut front sight from sig. The TFO will not clear the slide on the P320 without being undercut like Truglo provides for sig.

The ones you linked to are fine, but don't order a standard set elsewhere.

9mm full size uses #8/#8, 9mm compact uses #6/#8

Just a heads up on sight #'s / heights. I just bought bought a P320F in 45acp and it came with #8's on the front and rear. Me and 4 other shooters put a total of 300 rounds through it, and it's spot on.
Make sure that you confirm the sight #'s on your particular gun before ordering new ones Wink

While that's the general trend, I've seen reports of Full Size 9mms with 6/8 and Compact/Carry 9mms with 8/8.

There doesn't seem to be much uniformity.

My 2015 compact has 8/8's and roommates dec 2016 carry has 6/8's. You're right about that, shits all over the board.

Yep, all over the board.

FWIW, Sig CS told me that the P320 sight numbers are the same as the classic P-series. Got that in an e-mail from my CS rep when I had some slide work done. Didn't clarify whether that was slide length, caliber or both. Consistent with what Rogue said above. Regardless, use your Sig OEM numbers as a guide.

I suspect they will install a different sight number at the factory if post mfg testing shows a large sight POI discrepancy. Just a guess though.

I replaced the Sig sights for my P320C 9 mm and FS .40 with Heinie SlantPro black/black. The Heinie sights don't differentiate by caliber, they use only model number. Heinie #330P for P226 & P239, #332P for P220 & P229.

My own P226 .40, P320FS .40 and P239 .40 came with Sig 6/8. Same calibers, but markedly different slide lengths (re P239).

My own P229 .40, and P320C 9 mm came with Sig 8/8. Slide lengths the same, but different calibers.

I've replaced the Sig OEM sights with Heinie's on P226, P229, P239, P320C 9mm and P320FS .40. POA/POI is just fine on all of them. However, nearly all of my shooting is defensive draw/fire drills between 15 yards and 6". If you're doing 50 yards, POI may or may not be acceptable for you.

Confused yet?

I have found #6/8 on two of my pistols (P320c and P320sc both with night sights) and #8/8 on the third (P320sc with contrast sights). All are 9mm.

My P320 Full Size has 6/8.
My P320 Compact X-Change Kit (that I sold) had 8/8.
My P320 Carry has 6/8.
All 9mms.

After reading the replies I took a closer look at the sights and see the number is actually stamped on it. Good to know.
I will be ordering the ones from the Sig web site.
Thanks.

So, is the #8 front sight higher or lower than the #6?

If you are gonna get TFO's get the TFx pro models

#8 is .220" tall and a #6 is .230".

The higher the number the higher the POI.

Ok, thanks for the info. My 320C has a #6 front sight and is shooting waaaay low, so it looks like a #8 is in order.

So these listed here will require additional modifications?

Checked my P320 FS .45 ACP last night. Both #8.

Good information here. We recently had a fellow bring in a newly purchased full size 9mm 320 that he claimed was shooting several inches low at 10yds on its first visit to the range. Both he and a shooting partner were getting the same results. Upon close inspection of the gun I found that it came with #6 marked front and rear sights. At the time I thought that didn't seem right but we were quite busy at the time and didn't have a computer free to search for more data, so the only advice I could offer was for him to contact SIG CS and verify if those are the correct sight heights for a full size 9/40/357SIG slide.

I use the standard TFOs #8 front and read for my 9mm and 40 exchange kit. They work great for
Me
