Does anyone know if an Airsoft slide and barrel conversion kit is available for an HK USP, maybe for indoor training? The reason I ask is because I recently aquired one and the frame seems to be very well made compared to the slide which makes me wonder if it use to have a .45 ACP slide on it. I don't think it's an actual HK made one but probably a clone. None the less it looks like an actual firearm.
Thanks, Mike
