Hey all-

I have searched for threads discussing areas to polish to clean up the double action pull on P22x Sigs. None of them, however, had any pics of exactly what areas to polish or how much.
I have a West German P228 that I am upgrading with the E2 hammer strut, seat, and 19lb hammer spring. While it's apart, I would like to polish up whatever is needed.
Does anyone have any pics or links to share?

Thanks,

Bruce

The advice I received long ago was to polish the lower part of the strut that fits into the mainspring and the inside of the mainspring itself. The latter can be accomplished with suitable polish on a cotton swab having a wooden stick.

What can be more important than polishing the lower part of the strut, though, is to check how the top (head?) of the strut contacts the sides of the slot in the hammer that the head fits into. I have seen actual gouge marks in the strut caused when the hammer rotates as the trigger is pulled. The interior corners of the slot are usually a sharp 90° angle, and sometimes even seem to have a bit of a burr. Breaking and polishing those corners and removing any burrs can eliminate a major source of friction and dragging when the trigger is pulled in the double action mode. If there is no sign of major rubbing there, the sides of the top of the strut where it fits into the hammer slot can still be polished.

You can buy a pre-polished strut
from Gray Guns or The Sig Armorer.

I have seen those before. I want to see how much of a difference the E2 parts will make. It would be useful to handle one of the boutique struts to see where the polishing is done but I haven't had the opportunity.

Normally you just round the edges off of the strut where the spring is.
The New style(short strut long base) one I have could definitely use some help if I were to use it.
The E2 struts that I have with the Superfinish are already nicely rounded and far better than the New and Old style ones.
On my 226 Legion the PO had ran a buffer over the edges of the strut and removed most of the Superfinish. It was no smoother than a brand new one that wasn't buffed.

The Gray Guns and Sig Armor struts are not just polished and coated with a slick finish.
The geometry is changed to allow the spring to compress in a straight line instead of compounding on one side and making contact with the strut.
I have both sets.
The SA comes with a 20# spring.
The GGI one comes with 18 and 19# springs with a base. I used the 19# one in my 226.

With the SA Superstrut.


E2 strut.


I swapped out the spur hammer set with an E2 system on my 220 that I thought made a better trigger.
If the Superstrut had been out when I converted to E2 it I would have used it instead.
I do still plan on getting one for it down the road.

The Super Strut by The Sig Armorer has a "Nickel Boron Nitride coating" as stated on there website which will offer greatly reduced friction

You can pretty much polish all of it. Or anywhere that's touching something else anyway.

Where it interacts with the hammer, where its slides through the strut/shoe, even where the spring rubs on it. It's not going to hurt and can only help. All depends on how far/crazy you want to go. The "ounces equals pounds" motto applies in many places.
