Looking for suggestions for a threaded barrel for my P320-M17. The first I tried from Brownells did not have the necessary cut for the loaded chamber indicator. The LCI is easy to remove but not something I want to do. Hoping SilencerCo or other will begin making one in the next few months. I've probably got 9 months or so before my NFA paperwork is approved.

These guys might be able to help you as well, they can weld on the threads to your existing barrel:

Thanks for the suggestions.

BTW, Barsto will use the 13x1LH threads if you ask; for me keeps everything consistent - even had my glock barrels made up that way.

Ended up removing the the loaded chamber indicator as it was no longer visible after installing the ACRO. Added a SilencerCo barrel.

How do you like the ACRO?

Thanks. I’ve been very happy with the ACRO although I haven’t been able to put a lot a rounds through it yet. It looks a little boxy but that’s really not an issue when acquiring the dot. I do appreciate the concept of the sealed emitter and will take that over some of the slimmer, traditional designs. Now, just to wait a few more months until the can is approved and I finish out the setup.

I went with the SilencerCo barrel as well. It mates perfectly to my SilencerCo piston and Mini Boss suppressor.

Osage County seems to sell a P320 Full Size thread barrel. I don't know if it's a factory made barrel because I can't seem to find that same barrel on Sig's website.

description says OEM but no mention of thread pattern. asked a guy at my LGS about TB and he said a Sig rep told them they weren't going to make TB's for the 320 series but he could have been FOS??

Thanks

It was an available line item at EuroOptic when I (back)ordered my ACRO P-1 last year. My P-1 is riding on my M17 as well.

The base I have is an Aimpoint mount that shipped with my ACRO. Mounted it and fired a few rounds only to realize it was still loose. I modified the base to fit the correct M4x.7 screws which I purchased at a local big box store. This involved both mods to the base plate and to the screws as the ones I purchased protruded too far through the base and obstructed the extractor.

I need one for my M18.

I can confirm Sig does sale a P320 / M17 threaded barrel. It took a while going around with the salesman on the phone but note the item number (8900315 BARREL, P320, 9MM, 5.5IN, CIP, THREADED, 13.5MM $149.99) I found on the invoice if you would like to call an order one. They do not have it listed on their site yet but sounds like they will in a couple of months. I just ordered it yesterday so I can't confirm if it has the round indicator cut yet. I have seen others that order it from Sig (why I called to order mine) and there's does match the factory barrel but longer with threads as expected.

^^^The same Barrel is also currently listed on Osage as 'Out of Stock' --> https://osagecountyguns.com/sig-sauer-8900315.html

That said, I've heard that SIG will be changing their Threaded Barrels over to 1/2 x 28, sooo if you want your Barrel threaded in 13.5 x 1mm LH, you should probably procure one as soon as you can locate one!

I can confirm it Does NOT have an LCI Notch (Will NOT work with the M17 unless you remove the LCI)

Race, you've got this in-hand and can confirm the metric thread pitch? None of the sites it's listed on seem to be showing the 13.5 in the description.
