Looking for a SWAT pistol with the flip up front site in particular, not the hooded FS. Is there a particular model I can have my dealer order from SIG?

flip sight for 556p

iirc sig does not offer that sight any more. the hooded fixed sight is the correct height to mate with the diopter rear.
the old flip sight will fit , if you wanted to change it out. SIG may still sell them as replacement parts.
you might find a used early 556p on gun broker, the early ones came with the flip sight.
