Christmas came early in this household. The Silencerco Sparrow SS sounds a whole lot better than the plugged up AAC Pilot with over 25K rnds through it (it's a sealed can and cannot be cleaned, whereas the Sparrow is the easiest to clean on the market. I haven't shot anything through the TiRant 45 yet. I need to pick up a M16x1LH piston and a factory threaded barrel for my HK45C. Can't wait to do some more shooting!!!
