Mine keeps loosening up and slowing unscrewing as I shoot. Anyone else have this problem?

My Sig MK-25 does this as well

I had one that did that.
I bought a O ring and put it on the barrel.  
I holds on now.

Make sure the O-ring is high temperature safe.

Well, I will be shooting mine on Thur for the first time - so, I will see...

Doesn't sound good you better sell it to me.

Mine loosens also when firing. I just check it after a couple mags and snug it up as necessary.

Slightly annoying. Not as annoying as my Springfield loaded 1911. The Alan screw in the rear sight unscrews and about every 50 rounds is just about to fall out. Got a new screw and everything but did not fix the issue.

In before the one-handed stigmata.

I put 215 rounds thru mine today at the range - still on there tight when I cleaned the gun
