Doesn't allow proper cycling in a pistol - Kaw Valley Precision OPMOD Mega Hybrid-K Linear Compensator

Tried this on a 1911 45 acp and it wouldn't allow ejection of the cartridge. Possibly too heavy and counteracts the proper tilt action of a pistol. On top of that, I don't feel much reduction in recoil. The smaller versions of this like the one for 9 mm feels like they do what they're supposed to.
