Question Regarding the double roll pinned Breech block on older model sigs, and solid pin on newer models.

I don't know about you, but I personally cant stand the look of the roll pins on the older model Sigs and much prefer the solid pins on the newer guns.

I noticed that most of the Sig parts kits out there these days will come with a solid pin. Those of you with the older roll pinned slides, I was wondering if any of you have successfully replaced the roll pins with a solid one. If it is do-able, and if not, why?

I also read on Sig forums today that apparently, the newer Sig 229 to come out have spiral roll pins to replace the solid pins that are on the newer stainless slides:eek: Their reasoning is simply because the solid pins were harder to remove, and apparently weaker.


Thanks.

I generally stick with OEM because everyone I've seen whose tried to change those double roll pins has come a cropper. Bear in mind not all the breechblocks are the same, the older breechblocks had a bit of a gap between the bearing surface of where the pin goes into the block and the hole in the slide, around 1996 they expanded the breadth of the block in that area to take up the slack. What used to happen was that the pin would bend slightly and eventually crack, had it happen myself.

The double roll pins have a bit of springiness to them that a solid pin does not so recoil does not affect them as badly, at least that's the theory.

With the stainless slides it's not such an issue obviously because the slide is one piece.
 
Could be wrong, but the solid pins look larger.

I asked the same question recently (only because I was having a hard time locating new 2-piece roll pins) and was told I would damage my slide if I tried to use a new pin on an old 2-piece slide.

If you can't stand the look of it, get a new Sig!

Also to note is that the new solid pin is made to fit a tapered hole(directional) of the solid machined block slide rather than the straight hole of the stamped slide and breech block.

I was hoping the hole could be enlargened to take the solid pins that are very much available. Can be reamed out right?

The newer guns are shipping with new style spiral roll pins. Not the same as double roll pins on older guns.

If the diameter of the roll pin is smaller than or the same as the smaller end of the solid taper pin it should be taper reamable to fit a solid pin correct?
 
noted about the gap.

The newer one piece pins will not fit the older stamped slides. The pins have dents on them that bite in the milled stainless steel slides, they will damage the older stamped slides.

You can still order a set of roll pins for the older slides, you'll need to call the dealers to be sure. Questar carries Sig.
 
Yes I read the OP.
However he doesn't have the choice. He can break his Sig if he wants. It's a gun that was designed to work, not to be a piece of art, ok I find Sigs to be beautiful, but it's a working gun FIRST. Your enemy (those vicious targets) doesn't care if your roll pins look pretty.

so in short, I'll damage the gun if I do this mod. Got it, end of story.
