Hello:
I have a set of Wood Grips made by 'Altamont' I would like to install on a Sig P229. Problem is the screws are way too short from the OEM original grips. I have heard that using sig P239 screws would do the trick and have enough thread to handle the additional wood grip thickness. Does anyone know if this is true or not? Any guidance is appreciated. Thanks Brian

Welcome to the SIG forum!
I can't tell you if P239 screws will work for you.
Use whatever screws with the correct diameter/threads per inch if English threading, or Metric diameter/pitch, whatever works for you.
Be certain they are not excessively long and don't protrude inside the grip frame, as they will interfere with magazine insertion.
You also want almost full thread engagement length in the frame, about a thread from being flush on the interior of the frame.
With you using Altamont grips, you "may" have to buy excessively long grip screws, and shorten them to the proper length.

Also, if your P229 has an aluminum frame, be gentle on the grip screw torque. With aluminum frames it's relatively easy to strip out the tapped/threaded grip screw holes in the frame.
Stainless frame p229, it is less of a concern.
Most people will use a tiny drop of extremely light duty thread locker on the grip screws so they don't back out.

Wouldn't Altamont have the correct-sized screws?

I just modified a set of Altamont DAK grips to SAO and installed on my 229.
Yes the 229 grips screws are too short.
I used my 226 SAO grips screws in the 229 wood panels they were longer and did the job.
I have had the 226 for a long time do not know if the screw lengths have changed since I bought it.
Also if the 239 grip screws are too long one could buy 4 rubber o rings to shorten the length if you go that way.
I saw a link about screw lengths will find and post here.

Now My 226 grip screws might be completely different from newer model screws. 226 left 229 LEGION!!!! grip screws right.

OK.
First a big Thank You for all those that replied. Here is what the final verdict was.
I confirmed that the P239 grip screws were the answer. The original P229 screws were .155" diameter and the P239 screws are .153", a tiny bit smaller but work well. Cyberphobia was kind enough to show the various grip screws diagram above too for reference. So, if you have a P229 with Wood Grips that need longer screws, then the longer P239 screws are your answer. I got mine for $2.95 each for a total of $18.75 shipped to my door. Got them from Top Gun Supply over in Chesterland OH. Great folks to deal with and very reasonable prices and quick shipping. Hope this helps the next guy having the same problem. Thanks / Brian
