Cold weather function of my SIG

[matt]

I was at the range today in the cold and rain. After about 1.5hours I picked up my Sig226 (I had been shooting other pistols in the mean time) to show it to "Kevin9" and let him shoot it.

I pulled the trigger once to demonstrate the DA trigger and then went to do it a second time, but the trigger mechanism was sluggish due to the cold and wouln't reset. I had to push the trigger forward by hand to get it to reset.

Any suggestions on lubricants that are less subject to this? Do I need to pull it all apart to do a detail strip (It has ~1500 rounds through it so it is probably time anyway)?

Thanks,
Matt

Use gun scrubber or some other gun degreaser and blow all the gunk out of
there. Take the side panels off and check the spring for any gunk or
obstructions. Get lube into the trigger mechanism (front and
back) and main/hammer spring. Use a light lubricant that stays put, like mpro7
oil or even BF/CLP. Sigs generally like to run wet, so don't be shy
with the lube... just wipe off any visible excess and don't get any in the
firing pin hole.

This sounds bizarre, though... check your trigger return spring (beneath
the right panel) and see what version you have. The newer TRS's have
a curly-q type spring like a pigs tail, the older ones just have a bowed
piece of music wire. If you have one of the old ones you might want to
consider replacing it with the new style. (Brownell's probably has it.)

It's also possible the TRS is broken entirely, not sure if you examined it
when you got it home.

Another thing that can cause this is interference with the grip panels... make
sure the TRS isn't touching your grip panels in such a way that there is
interference. (You can tell by working the trigger with the grip panels
on. )

Well, I soaked everything with Gun Scrubber. Turns out the area that was sticking was between the trigger linkage (a flat piece of sheet metal) and the frame. There is a large amount of surface contant there and there was some gummy build up in that gap gluing the parts together.

It is the old style spring in there. I'll have to look at the new one and maybe try it out.

Thanks,

Get the Sig armorers DVD from Brownells. You can take the frame down and get the trigger bar out with only a screw driver. Makes it much easier to clean and can definitely improve trigger pull. Also helps to clean and polish the inside of the mainspring. If you have the old metal mainspring seat you can replace it with the plastic mainspring seat and use a lighter mainspring and get ignition that is just as reliable and a much nicer DA pull.

Depending on the age of the gun you should also replace the decocker and the reset spring. They can function indefinitely but do break and wear out.
