    Now, I'm sure that everybody has their own ways to go about this and this certainly isn't the ONLY way to clean a 391, but it's how I go about doing this. In this case, I am cleaning my Son's 7 year old Urika that has approx. 25,000 rounds and has never had a "thorough" cleaning. I will not go into disassembly....I figure that most of you that have a Beretta auto already know how to go about this, but I will start off with replacement of the recoil spring, being that it is a good time to do so.

    First, I heat up the spring cap area with a butane soldering iron with a torch tip installed. This is important because there is thread sealer on the caps threads that is pretty tough stuff-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view&current=100_1462.jpg" target="_blank">[​IMG]</a>



    Now, the gun is basically gutted. I have the metal parts soaking in mineral spirtits a I've sprayed the receiver area and magazine tube with WD-40 to loosen up some of the carbon-

    Parts in mineral spirits

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1486.jpg" target="_blank">[​IMG]</a>

    Now, I take the gutted receiver that is sprayed down with WD-40 and scrub the magazine tube and magazine tube cap with a scotch bright pad. I use scotch brights quite a bit for cleaning not only the these parts, but others as well-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1465.jpg" target="_blank">[​IMG]</a>

    If there is excessive carbon built up on the magazine caps shaft, don't be afraid to clean it off with a fine wire wheel (WEAR SAFTY GLASSES)-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1469.jpg" target="_blank">[​IMG]</a>

    Now that it's scrubbed down, clean everything off with automotive brake cleaner (IN A WELL VENTILATED AREA, fumes are dangerous, especially if sucked into a heater)-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1467.jpg" target="_blank">[​IMG]</a>

    Nice and clean now-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1470.jpg" target="_blank">[​IMG]</a>

    Now, I take the valve nut and counter nut loose by using the factory Beretta tools like a pair of pliers. You also reassemble in the same way, but the tools will be in the opposite position-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1492.jpg" target="_blank">[​IMG]</a>

    When the valve shaft is removed, it is often carboned up pretty good, so take it to the wire wheel-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1475.jpg" target="_blank">[​IMG]</a>

    At this point, I'll show you some of the cleaning tools. They are all available from either auto parts stores or your local hardware. They consist of an oxy-acetylene torch tip cleaner and small wire brushes in varying sizes-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1477.jpg" target="_blank">[​IMG]</a>

    Typically, I will clean out the barrel ports with the torch tip cleaner. If they are plugged, then I'll use a 1/8" drill bit-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1481.jpg" target="_blank">[​IMG]</a>

    The cylinder has a tendency to get carbon packed in some areas. To loosen this, you can fill a can up with mineral spirits and soak the cylinder area over night, then take a small screwdriver or pick and scrape loose the carbon..usually, it will come out in chunks. Then, take a stiff wire bush and finish the cleaning-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1483.jpg" target="_blank">[​IMG]</a>

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1484.jpg" target="_blank">[​IMG]</a>

    Now the piston. There is a small snap ring inside and you'll need some small snap ring pliers. Once the snap ring is removed, remove the collar and clean it with wire brushes, then clean the inside of the piston out much the same way that you did the cylinder, with a pick and brushes. The exterior of the piston can be cleaned with the wire wheel-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1488.jpg" target="_blank">[​IMG]</a>

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1487.jpg" target="_blank">[​IMG]</a>

    The barrel, I first use a wire brush attached to a cordless drill. I also clean the choke tubes with the cordless. Then I run a patch through the barrel-

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1493.jpg" target="_blank">[​IMG]</a>

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1494.jpg" target="_blank">[​IMG]</a>

    <a href="http://smg.photobucket.com/albums/v712/Tronspace/?action=view¤t=100_1496.jpg" target="_blank">[​IMG]</a>

    Once the gutts have been removed from the mineral spirits, clean with brushes and scotch bright pad, the reassemble. Spray internal parts, magazine tube, piston and valve assembly down with Breakfree CLP and shoot the gun wet. After the days shooting, remove forearm and wipe off Breakfree, the reapply.

    You're good to go for thousands of rounds!

    Tron, thanks for going to a lot of trouble to take photos of the cleaning process. Pictures are indeed worth a thousand words. To new shooters your photo demonstration is invaluable. Ben

    OK Guys....now look. I'm not going to try and explain things about beer bottle caps and bottles. A lot of people come over and may have a couple here and there. I always say "My fridge is open" and I mean it.....just help yourself. You would be surprised at some of the shooting celebrities that come over.

    My cleaning method is very simmilar to Tron's. Including the hands. It's more work to get my hands clean, than Cleaning the gun.

    Yes Rev, The Dawn degreaser works great. I use Palmolive liquid though. When people come over and ask me what I use to clean their guns, I tell them "You're soaking in it"....that always raises an eyebrow.

    BarFin, if your forend cap is stuck, it's probably because it's the old style cap that has a tendency to corrode in place. The new type has stainless steel insterts and plunger. No, DO NOT heat it! You may need to use a pair of channel locks with a rag around the cap. Once you get it loose, throw it out and get a new stainless unit from Angleport and you wont have that problem any more.
