    I have a Taurus PT-140. It has been a really great little gun. The problem I am having is what lubricant to use. For some reason my 140 does not have as smooth as a trigger pull as I would like. It used to be much smoother. I made the mistake of cleaning the gun with some of that gun scrubber stuff. I am thinking that whatever lubricant the factory used was cleaned out when I used the GS. There is a linkage on the right side of the gun that goes from the trigger to the piece that pulls the firing pin backwards. That linkage slides along the polymer. That seems like it is the point of friction.

    Any advice would be helpful. I am currently using a basic oil with Teflon. I am looking for a lubricant that would be good for that metal to polymer contact.

    You may want to consider gungrease, or white lithium grease.
    Heavier and will stick to where you put it. I lube my rails with the stuff.

    I have been using Militec on my polymer guns (mostly HK USP's, but a couple of Glocks too) w/ really good results. Plus a liitle goes a long way.

    A shooting buddy of mine was cleaning one of his polymer...er...plastic mags w/ gun scrubber & melted parts of it together. That was the last time I used Gun Scrubber on any of my guns.

    I enquired with Walther if Ed's Red would damage my P99 if it were to take a dip in the stuff. I provided the ingredients list. If the polymer composition were known to me, I could easily consult one of several plastics sensitivity databases to see if any of the recipe constituents would be potentially damaging, but I don't. The response from Walther (S&W actually, in all likelihood) could be condensed to, "I don't know." :scrutiny:

    Anyone know what plastic(s) the P99 is made of? :confused:

    To answer the lubrication question: I use Tetra grease.

    I used FP-10 on my polymer guns. P99 and XD-40.
    For full metal frame guns. I use FP-10 for lube and Militec1 Grease. The combination works great!

    I doubt that any of the companies making plastic framed guns will tell you what kind of plastic it's made of. My dad works in a chemical plant and has access to Gas Chromatographs (sp?) and could probably tell me should someone be willing to send me a "sample" of their frame. ;)

    Gun Scrubber is almost 100% acetone spray. Any plastic used in a gun should be resistant to it. The only thing I've read is that they think the acetone may leach out some chemicals in the plastic over time and make it brittle. If you see a piece of the gun melt from it, the gun maker should be shot. If you see it melt paint or some kind of lacquer finish, that is correct. Acetone will attack most paints.

    sturmruger,

    I have a PT145. Very similar. I do use Gun Scrubber about every other cleaning and it works well. Gun hasn't melted yet.
    I use a few drops of CLP on the trigger bar which works well for me.

    Be safe.

    In general, gas chromatography will only work for volatile and semi-volatile samples (say stuff with a boiling point less than around 300 degrees celsius). I am guessing that most of the polymers have boiling points above that.

    NO ACETONE ON PLASTICS

    IMO...If your gun had a good trigger before the Gun Scrubber...youve probably tweaked your plastic parts....I dont know if anything but shipping the gun back to Taurus will fix it!

    Given that is a viable possibility...as for your question.
    Steel/Poly contact surfaces use regular lube...Breakfree CLP
    What ever works for you on other guns...
    Poly's are pretty much self lubricating...(lubricous by nature..slippery by design) and require less lubing maintenance than steel/steel contact surfaces.......

    Acetone/similar chemicals (MEK ETC) is very corrosive to most plastics...even some more resistant ones...HDPE, UHMW.....not TEFLON...but its impervious to everything.
    Brake cleaner, gun scrubber etc etc....will harm plastics very very quickly.....
    Acetone is the primary ingrediant/whole ingrediant in nail polish remover....nail polish is mostly acrylic/polymers...clear with color molecules.....

    DONT USE ACETONE ON ANY PLASTIC...ESPECIALLY GUNS!

    Call your local crafts/chemical stores...search the web/try it...if you dont believe me.....:eek:

    The boiling/melting point for most common plastics is between 2-300 deg F.....not C. Polys/Acetols/Nylons/Acrylics are all in the very low 200's....The highest rated commonly available plastics is TEFLON....its around 500 deg F....is sinters at just over 640 F.

    Shoot well
