Sabotloader,
My .45 Omega, to the best of my knowledge, was bought by the origional owner with the laminated TH stock. It still has the QLA. The only thing that was done with it was the flash hole was drilled out to .035. I have since replaced it with an origional plug with whatever flash hole size TC uses and it does great with BH209. It has never misfired on me.

You might be thinking of my .45 Encore Bergara barrel that Bellm cut the QLA off and recrowned.
