This is a mock suppressor made specifically to fit the Umarex Airsoft H&K USP .45 and is very likely to not fit any other airsoft handgun. I have included 3 different models. MK3 is the final completed model and fits very well and snug. MK2 will fit with some modification to the plastic slide which wont be necessary if you use MK3. MK2 and the original file are included in case you want to mess around with them. I recommend printing any of these with ASA filament, as that is what I've used to print mine and have found it holds up moderately well in a more aggressive environment.
