I don't own a 2011 but I own Glocks, 1911's S&W revolvers and they all go in my US cleaner, plastic parts and all. No issues at all. I run the Glocks about 30 mins.
I have a Lyman US, TURBO SONIC 6000 ULTRASONIC CASE CLEANER. It will hold 2 guns. For the small part I use Rubbermaid screw lid containers that I have drilled 1/8" holes in the bottom and about a quarter of the way up. After running the machine, I rinse in hot water and blow dry using the basement air compressor (20gal tank).
I tried the Hornady solution but found at it didn't clean as well as the Lyman.
YMMV.
