Assistance identifying magazines

Mag 1 is not a Colt or Uzi mag unless it's a really weird aftermarket mag. It MIGHT be a MAC-10 mag. MAC-10's will take Grease Gun mags with minor modification. Does a 9mm or .45 round fit?

Need more pics of mag 3, front bottom and other side. Also see what is the biggest round that fits, and how many. Does a 45acp fit?

Does mag 4 have a square-ish notch in the upper middle front ?
(Mag catch notch pics really help with ID. For example, many older double stack wonder nines use a S&W 59 pattern mag with the catch notch in a different place.)

Mag 5 looks like Raven .25
(D'oh! I type slow. SkyHawk beat me to it. )

Here is a photo of the notches on the front of magazine #4.

Here are more photos of magazine #3 & it fits a 380acp

Well it's not a Ruger magazine, it's a basic S&W pattern though.

Ok I believe mag 3 is a Savage 1907 / 1917 mag. It could be worth up to $100 - $150.

It has mag catch notches for either pistol (one high and one low).

The big D shaped mag catch notch on the #4 magazine seems very distinctive, unlike many 9mm double stack mags for the common stuff.

Just bumping this to see if anymore input is out there! Thanks again everyone

Mag 4 could be for a bersa.
They have the big D cut and many different variants, some having the notch on the tapered part of the mag and others down below where the body is straight like your picture.
