    Looking after a Gamo compact pistol

    Hi all
    I only use my pistol every now and then but do I need to do anything to keep it in good condition.
    I am not sure if I need to keep the barrel good with a small amount of oil and do I need to do anything to the seals
    Thanks Dave

    Hi Dave

    Maintenance on the Gamo Compact is easy, when fully opened there is a tiny hole in the cylinder body, a TINY drip of oil in there once in a blue moon will maintain the main seal... the pivot pins are very easy to drip a small amount of oil on to in order to keep them free

    I've owned a few, and periodically the valve may stick, usually in the open position, which means you cannot 'pump' or prime the cylinder - removing the whole valve assembly to lubricate the seals (and polish up the valve stem while you have it apart) is not a massive job, just fiddly.. the tiny drop of oil in the main cylinder described above should allow enough oil (a really tiny, minute, atomised amount) through to the seals in the valve and prevent this

    I know Crosman used to do very light oil for lubrication their pneumatic and Co2 pistols - not sure what others on here would recommend, but I got a small bottle of silicon oil intended for running machine belts and use that

    I wouldn't put oil of any kind inside the barrel unless you were storing it indefinitely..... you'd need to get all of it our before using pistol again otherwise it will be innacurate at best, and at worst will diesel horribly

    I can't find any of the Crosman Pellgun oil at a reasonable price, but found this

    Or search on fleabay for silicon oil

    I would just put the absolute tiniest drip in and then fire a few shots, that should spread it around, and you can't repeatedly open and close it - you'll need to close and fire it off every time to cock it

    Would this be the same for a PR45, with the plastic piston? I only ask as mine hisses when cocking, and I've changed the seal already.

    The PR45 is essentially the same gun. The hiss on cocking is air being drawn into the cylinder. It's normal

    Yup, same gun, but with a much better trigger mechanism, and a much nicer grip.
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    I used to oil the pivots occasionally and then a small drop of either Crosman Pellgun oil or ATF on top of the air admission hole on top of the cylinder before the top lever was fully open to get drawn in and lubricate the valve seals (about once every tin of pellets).
    It won't diesel and consistency was unaffected.

    Trouble is you can't keep it confined just to the seals as all oils migrate with use.
    If it gets anywhere there is any metal to metal contact it will cause galling.
    But it's your choice...

    I have purchased this seal oil I am confused now so is this oil OK to use on my Gamo compact seals https://premium-quality-air-rifle-ac...5ml-p430240097 I can always buy some Pellgun oil.
