I put my Sig with factory night sights in with no problems and my cleaner is 780 watts. So I would think yours would be fine.I've been running all kinds of parts through it today, I'm just too scared to drop night sights in yet
It did a heck of a job on my BCGs as well as my .22 conversion (that thing was pretty nasty),
I've been reading on a few different forums that the majority of folks have not had any problems with night sights, but I'll need to research just a little more before I get my confidence up
