226 shoots low with new barrel Login/Join

Hey guys, I got a 1996 226 9mm. I bought a silencerco TB for it. It consistently shoots about 3 inches low with this barrel in the gun. With the factory barrel is shoots right on the money. Anyone know why it would so this?
The gun functions with either barrel flawlessly

I’d call silencer co and see if they will swap it out. Sounds like it isn’t fit right

3" low at what range? And we're assuming you mean with no suppressor attached?

That's interesting. A few months ago I purchased a Silencerco TB for my P320 FS 9mm RX, and took out to the range for the first time two weeks ago. It shot about 4-5 inches low at 12 yards, no suppressor.

Since I also had my older P320 9mm FS with me I swapped that OEM Sig barrel into the RX. It came right back to POA, only change was the barrel.

I moved on to shooting other pistols that day and haven't gotten back to the testing the threaded barrel. If same results as before I will have to contact them.

Wow, that's quite an offset. This is interesting. Why would threaded barrels do this?

I have tested a threaded barrel in a P229. It does change the POI, but only about an inch @7 yards, and the offset is higher, not lower (probably due to the longer time the bullet is in the barrel relative to the recoil cycle).

Which is also about 3 inches @7 yards. Interesting. Anyone have an answer?

I have changed barrels in a number of pistols. Some drop-in,some fitted. Even if the new barrel is factory, or an aftermarket drop-in that actually drops in, I never expect two barrels to shoot to the same POI. Every barrel sets up in the pistol slightly differently. A thousandth or two difference in dimensions here and there,can still be in spec, but can still make a difference. Assuming all is in spec with your pistol and both barrels,and not being able to personally inspect the pistol,I wouldn't be surprised if this is the issue.......ymmv
