I have a Sig P-226 SCT that came with rubber grips from the factory. The picture below is when I first bought it. I decided to pick up a nice set of Sig wood grips that were on sale from CDNN. These are the grips. Note they are of Sig Sauer manufacture.
https://www.cdnnsports.com/sig-sauer-p226-hardwood-grips-silver-medallion.html?___SID=UThey looked good, and were a good deal, so I bought them. Now the problem. The stock grip screws that came on the gun with the rubber grips are
too short for the wood grips. What you have to do is purchase grip screws for the Sig P-239. They are longer, and will fit the wood silver medallion grips on a Sig P-226. This type of thing becomes a total pain in the ass. Here is a good diagram of all the different grip screws Sig employs on all their different models. Note all the different head thicknesses and lengths.

This is good to have for anyone who is planning to do any grip swapping on Sig handguns. You will run into the same thing I did. Just so you don't think I'm picking on Sig, I ran into the same crap on my Browning Buckmark Camper UFX. I changed out the black and grey rubber grips for a nice set of Browning Cocobolo grips. And those screws had too big of a head to work in the Browning wood grips, forcing me to buy additional grip screws that would properly fit the Browning Cocobolo grips. Remember, I'm talking about Sig grips on a Sig handgun, and Browning grips on a Browning handgun. Not any aftermarket grips. If these grips are manufactured by Hogue or someone else for Sig and Browning,
they are made to their factory specifications. Or at least should be.
I cannot understand why the hell these manufacturers can't get their $h!t together, and make sure all of their grips are counterbored the same diameter. And to the
same depth from the back of the grip. So one grip screw would work in all the grips they produce for that gun. We've had interchangeable parts on mass produced goods since the Industrial Revolution for God's sake.
I will say when I changed out the grips on my Beretta 92-FS from plastic to wood, (again the wood grips were of Beretta manufacture), the same screws did work. Although I had to ditch the star washers that came with the plastic grips. No big deal. At least I didn't have to purchase new screws. These are the P-239 grip screws I had to buy, so I could make my wood Sig grips work on my P-226 Sig handgun.
http://store.sigsauer.com/p239-grip-screws-5-blued.html$24.00+ including shipping and tax for 5 screws. Add that to the $50.00 for the grips, (including shipping), and I'm up to $75.00 for this whole deal. Still not bad because Sig charges north of $110.00 for most all of their wood P-226 grips on their website. I just wish I didn't have to research all of this nonsense to make it happen correctly. You shouldn't have to. Sig Sauer should at least provide a page on their website that contains the information I've listed here.
Anyway, I thought I would point this out for anyone thinking about doing the same. Sig handguns are very popular.
