I've been wanting a pistol in 10mm for a long time now. What I want is to get a conversion barrel for my kimber eclipse pro target. I have yet to find an aftermarket barrel in 4''. Im wondering if I could order a full size 10mm barrel from kimber and have it shortened to fit my gun? Also does anyone know where to find a quality aftermarket option? If I can find the barrel, will I have to change any other parts to make it work? I've also been told you can get a kimber in .40 and have the barrel reamed out for 10mm. Has anyone heard of this, and if so, does it work good?
