I've also been wonderin about that, most I have been lookin at are for the picatinny rail, or at least look to be, even the M3 looks like it would take the adapter or picatinny, and most don't make it clear what they fit... But to me it looks like the M3 does require an adapter to fit the USP...???Does the M3 need an adapter for the USP 45?
YesDoes the M3 need an adapter for the USP 45?
