These came slathered in Cosmoline.  For those who may not know, this is a preservative grease that is extremely sticky, especially the former east-bloc variant.  I didn't even want to disassemble the pistol before removing at least some of the grease.  And since the stocks do not remove via screws, but via levers inside the grip frame, not even the stocks could be removed first.  That made me decide to use Simple Green Pro, a plastic-safe cleaner I often use in my ultra-sonic cleaner.  That worked well, and then I donned gloves to take down the pistol as far as practical.  

As you may know, the M70 is an offspring of the TT-33 Tokarev, or the Yugoslavian M57 variant, and as such has a hammer/sear module that comes right out of the frame as a single unit, just like the Tokarev.  When that is out there is nothing left in the frame other than fixed cross pins and such.  So, I had everything else disassembled but I didn't want to disassemble the hammer module, as it is like a closed box with tiny parts inside.  I believed I could get it clean, use my compressor to dry it thoroughly, then oil it prior to reassembly.  That I did, and the rest of the pistol came clean, as expected, with one exception.

Of the three magazines I have, only one would come apart.  The mags are the standard type with a removable base pad with a hole in it and inner base with a raised portion that fits into the hole.  Spring pressure holds it firmly against the base pad.  The two that wouldn't come apart were cleaned ultra-sonicly for quite some time, and are not in any way corroded.  I believe the base plates may simply be pinched shut.  I decided not to mess with them for now, blew them dry with 100+ PSI of air, and wipe them down. In shooting, they all performed the same.

After lube and applying rust prevent I reassembled the pistol only to find it wouldn't cock.  Repeating reassembly a couple times only reaffirmed my problem.  A closer examination showed me that the sear pin was missing from the hammer module.   Was it missing as received?  Most likely my use of the air compressor fired a slightly loose pin into the no man's land that are the lost recesses of my basement shop area.  I don't keep pin stock around but found that a Glock takedown pin tool was just the right diameter so I cut it to size then use a fine file to shorten it so it fit well enough that the hammer module would go into the receiver without hanging up due to the new pin sticking out too far, and then polished the edges.  Pistol now works perfectly.

Off to the range a few days later.  I picked up a case of GECO (German) 73gr FMJ ammo.  GECO is both inexpensive and accurate.  The M70 is on the large side for a .32, and I can get the edge of my little finger on the grip.  Still I shoot it with my little finger under the mag base plate for comfort.  There is little recoil with a .32.  While the front sight looks small in the photos, the rear sight is tall and I could get a good sight picture.  Now for the good part.  This pistol shoots like a tuned target pistol.  I was shooting ridiculously small groups.  This one VERY accurate little mouse gun!   It is now my favorite. 

Condition on these from Classic is rated as VG/E.  Mine is probably VG.  Lots of tiny--tiny--scratches, and many tiny edge chips, but almost nothing major.  One exception, you'll note a curved scratch on the slide just above the slide lock.  I haven't a clue how that could have happen because you don't put the slide back in by swinging it down the slide, it goes straight in.  Well, perhaps some unknowing cop did it while being careless, or a distracted armorer did it.  The finish, which looks like phosphating in my photos but is actually blue, and a bit darker than my pix--I wanted to show the details--is starting to fade, but not bad.

I like this gun a LOT.  Truth be told, more than the Beretta!

ETA:  This is a singe action, and can be carried cocked and locked, though the safety is not firm at all.  The trigger is quite decent.
