Hmmm, I didn’t see the HTX on the Sig website. Not sure I want a 24” barrel on the Cross, but I can always cut it down to 22” ( my preferred 6.5 barrel length for anything other than a dedicated precision rifle). Is the only difference the hand guard & barrel?
My bad, I misspelled HXT.
This is where I first heard about the HXT:
https://www.vikingtactics.com/sig-cross-hxt/
The STX has the full length Pic rail on the hand guard. The STX is black, the HXT is grey. The STX has an Sig taper muzzle device, the HXT comes with the ring that allows a normal 90-degree shouldered brake to work on their barrel.
After removing all the loctited fasteners to pull the pic rail off the STX, required to remove the hand guard, required to remove the barrel, im not a fan of the full-length pic rail.
I like the grey better, and I have a TBAC brake on them both to mount a can. I added the PRS safety to the HXT.
For the cost savings, I can add a Proof Cross barrel or a SJArmory barrel. But the barrels have been pretty accurate (for a factory barrel) for me.
