Can you recognize these firearms for me?

They're like if a Suomi and MP18 had a sweet sexy love child

Modified MP18's

Unrelated to OP, but while played Jagged Alliance 2 1.13 I found a SMG I couldn't get any info on? Called a QTs 39, fires 7.62x25 rounds

bottom one is a PPSH, heck of a shotgun.

What is the reason for the different muzzle?

>>30654417
SIG MPKS

(the swiss SIG, not todays german one)

If I remember correctly the muzzle is suposed to prevent the gas filling the bunker when shooting from the small openings on the wall.

Thank you, all.

What are you using the information for, if I may ask.
