       This is the 9mm version of the handy,
  Marlin Camp Gun. This is the original version, predating the .45, and is a
  suitable companion to my 9mm pistols, and a nice compliment to my Marlin Camp Gun in .45 caliber.
  As with it's bigger brother, Marlin did not try to
  reinvent the wheel, but chose to use a standard magazine to feed the little
  carbine. In this case, it is the magazine used to feed the long line of
  S&W "wonder nine" handguns.  
       The S&W 59 series pistols have been produced in
  one form or another since the introduction of the venerable Model 59, back in
  1973. The series is still being produced today, in a number of different
  models, from full sized duty guns down to back up, and hide out models. The
  full sized guns used a 15 round magazine, while the more compact models had a
  smaller, 12 round version.  
       This gun was produced during the clinton magazine
  ban, and thus saddled with the government mandated (or was that emasculated?)
  10 round magazine. The magazine housing of the Camp Gun is sized to fit what
  was initially a 12 round magazine. This means that pretty much any of the
  magazines produced over the last three decades, for any sized 59 series
  pistol should fit. I have several old 15 rounders from the
  original Model 59, and they fit and function well. As can be seen from
  the photo, the 15 round mag sticks out of the bottom of the magazine housing
  a tiny bit. These magazines are over twenty years old, and used to belong to
  an old Model 59, which was one of the first guns I ever bought. Several years
  after the gun was sold, I came across these magazines, which I must have
  misplaced. I also have a pair of extended magazines which hold thirty rounds
  each. These magazines, added to the trio furnished with the gun, give me
  quite a bit of capacity, if I should ever decide I need it.  compared to the common .22. The guns themselves sold for
  about double the cost of a good quality .22. The ammunition goes for around
  eight to ten times the cost of the venerable .22 rimfire rounds. Going up the
  scale, a post ban version of a civilian semi assault rifle will sell for
  about four times the price of the Marlin (the preban versions being all but
  unobtainable), but the ammunition will cost about the same, or even a bit
  less. Thought of by plinkers as too much gun, and by
  sport and defensive shooters as not enough gun, the Marlin was ignored by
  both.  
      Considering the cost, popularity, and capabilities of some
  of the truly dreadful guns out there, like the civilian ingrams, tec-9's, and others of this class, it is a real shame that
  the Marlins are no longer produced. The Marlin is at least the equal of all
  of these guns in every way, and is superior in accuracy, and handling
  qualities, while costing less. With aftermarket magazines holding as many as
  twenty rounds (or even more in the case of some aftermarket 9mm S&W
  magazines), the Marlin can even match or exceed the vaunted firepower of
  these other guns.   
      Even better, since the end of the
  idiotic magazine ban, a number of hi cap magazines are available at
  fairly low prices, including some 9mm drums. The drums in question are from
  the old Soumi submachine guns. These are 72 round magazines, which are easily
  modified to fit the Camp Gun, as well as a number of other weapons. The total
  cost of conversion of the magazine is about $50, including the cost of the
  magazine itself (as of 2012). Time invested comes out to about an hour and a
  half. I presently have four such magazines. 
      The practical, utilitarian design of the Marlin has given
  it a sporting look, which makes the gun much less threatening than the
  military style carbines mentioned above. Though this unassuming appearance
  has probably hurt the Camp Guns in the self defense marketplace, I consider
  this style to be preferable to the more aggressive look of the military type
  guns which have become so popular. Marlin's decision to use the most
  pervasive .45, and 9mm magazines in the world means
  that there will never be a problem procuring magazines, which is often not
  the case after a semi auto firearm has been discontinued. I suspect that in
  years to come, these guns will be sought out and valued much as the old Ruger
  .44 carbine, and the old Dan Wesson's are today. All
  of these are cases in which a well thought out concept was dashed against an
  unready market.  
    
  My 9mm Carbine combo. This gun, and the S&W
  automatic, take the same magazines, including the 30 round extended
  version in the carbine, and the 72 round modified Suomi drum to the right of
  the photo. So far everything is working well; but I do wonder about the
  effect of the heavy Suomi drum on the plastic parts of the Camp Carbine. Time
  will tell. Used in the handgun, the drum is just silly; but then, quite a
  number of pretty neat things, including much of the gun culture, are pretty
  silly. The Camp Carbine here is loaded with the 30 round extended S&W
  style magazine.

     Disassembly
    and cleaning

     | 
    
     The
    Camp Carbine will need to be thoroughly cleaned after firing. This is one
    of the dirtiest shooting actions I have ever seen. It is also,
    unfortunately, not one of the easier designs to disassemble. Unlike many
    modern firearms, this is not based upon any sort of military action, and it
    was never necessary to make the design soldier proof.

     | 
    
     After
    unscrewing both disassembly screws, the receiver will drop free of the
    stock. The screws will remain in place, as they are held by retainers. 
     | 
    
   
    | 
       
     | 
    
     The
    receiver here is shown after being removed from the stock.  
     | 
    
   
    | 
       
     | 
    
     Before
    cleaning the action, it will be necessary to separate the upper and lower
    portions of the receiver. These are held in place by a pair of retaining
    pins. Driving these pins out, will permit the action to be opened. 
     | 
    
   
    | 
       
     | 
    
     The
    pins may be gently driven out, using a small punch, or narrow screwdriver.
    In a well cared for gun, with no rust, the pins should slide out easily.

    upper and lower receivers after separation. The upper receiver is of milled
    construction, while the lower section is of molded plastic,
    and stamped metal.

     A
    look at the internal workings of the upper receiver, including a view of
    the bolt in place.  
     | 
    
   
    | 
       
     | 
    
     With
    the upper receiver turned upside down, first remove the guide piece, which
    sits on the left hand side of the receiver. It's
    removal will permit the removal of the bolt. There is a captive spring
    under the guide, which should stay in place on the receiver.  
     | 
    
   
    | 
       
     | 
    
     Pushing
    back on the bolt a bit, will allow for it's
    removal by pulling straight up. The bolt will be under a certain amount of tension
    from the recoil spring. The cocking lever will remain loose in the upper
    receiver, and may be removed easily.

    The cocking lever is shown just below, under my thumb.

     A
    view of the comparatively massive bolt. the size
    and weight of the bold is necessary because of the straight unlocked action
    of the carbine.  
     | 
    
   
    | 
       
     | 
    
     With
    the action cleaned, the bolt may be reinserted into the upper receiver. The
    cocking lever will need to be inserted first, and the two pieces lined up,
    so that the lever fits within it's recess in the
    bolt. 
     | 
    
   
    | 
       
     | 
    
     The
    guide is then replaced. It will need to be fit under the upper portion of
    the bolt, and then rocked down over it's captive
    spring on the receiver. The forward retaining pin, which holds the receiver
    halves together, will need to fit through a hole in the guide, making it's proper adjustment in the frame critical.  
     | 
    
   
    | 
       
     | 
    
     I
    generally replace the rear retaining pin first. This allows me to rock the
    upper and lower receivers for the best fit, and to adjust the feed ramp,
    and the guide.  
     | 
    
   
    | 
       
     | 
    
     A
    view of the lower receiver, with the action disassembled. A magazine is in
    place, so that the relationship between the magazine, cartridges, and feed
    ramp may be seen. The adjustable feed ramp here, is in it's
    upper most position.  
     | 
    
   
    | 
       
     | 
    
     Another
    look at the feed ramp, this time shown depressed, giving an idea of it's range of motion. The ramp must be properly
    oriented, during reassembly, or there will be constant feeding errors. The
    ramp is designed to sit just in front of the chamber of the carbine. The
    spring loading which keeps it pressed up against the rear of the chamber,
    also makes proper reassembly of the gun a bit tricky. The ramp will tend to
    press itself under the barrel, during reassembly, which will not permit the
    receiver sections to be lined up properly for insertion of the retaining
    pins. It must be guided during reassembly.  
     | 
    
   
    | 
       
     | 
    
     When
    joining the front portion of the two receiver sections, if the retaining
    pin holes do not line up correctly, do not force the sections. Instead,
    gently depress the feed ramp, as shown in the photo, until the receiver
    sections line up properly. It may also be necessary to adjust the position
    of the guide installed on the left hand side of the upper receiver, since
    the guide also has holes through which the front retaining pin must pass.
