Finding Weapons (Hitman: Blood Money)

In this topic, let's describe the weapons found, since some types are very rare and more difficult to find.
Nailgun, can be found in a mission in the White House, at a worker.
Colt 45, 1911, can be found in the White House and at the handicap at the end.
Garden shears in the mission New Life and Requiem.
KAZO TRG or whatever, in general a sniper, at the killer in chicken clothes.
SLP.40 with a silencer, in the same mission with a female hen.
Mauser at the Opera.
In general, then I will continue when I find more ... well, do not forget to write about hard-to-find / rare weapons.
