Here is a "basic" on the "more current" screws, there are only 2 diameters/pitches, a big difference between some is the head diameter, and thickness. The P220/P225/P225A1/P230 and P232 all use 5mm diameter with a .8 Threads per mm, the P226/P227(w/inserts)/P228/P229/P239 use a 4mm diameter with a .7 Threads per mm. Even though measurements are given in fractional dimensions on the "display", remember Germany uses the metric system for measurements...

Some of the very early P226 from Germany used a slightly different as shown below. Chart from Top Gun Supply, FAQ

***Edit - 7/3/20 with assistance from member MaverickDMD, it has been found that the early Sig Sauer Grip Screws, ase essentially the same as the Beretta M9/92/96 Grip Screws, at 3MM-.5 coarse pitch***

Also remember not all threaded lengths are equal. That is why on some models, there are washers used with the plastic/polymer grips, to prevent the screw threads from penetrating the magazine well, and interfering with magazines, but removed when used with thicker wooden grips to engage enough threads to prevent loosening or stripping out the aluminum frames threaded grip screw mounting points.

Some models such as the model P225A1 have a longer threaded shank (7mm) than any previous models (6mm), so use care,with a P220 or earlier P225 screw for replacement.

bearone2, you are correct... found it online while searching images, for "Sig Sauer Grip Screw Sizes" a couple of years ago, possibly from Top Gun Supply, as their net "address" is imposed on the image when cursor placed on it.

This "tool" is what I used to determine screw sizes too, to put credit where it is due!

No doubt a "German/European" design, if you look at the period grip panels, it seems that they would possibly "lock" into place in the grip panel, and not turn, so all of the friction was on the bottom of the head of the screw... the side of the washer with the "multiple teeth" would engage the "metal" of the screw head.

ORIGINAL P226 Grip Screws



Since the early P226 Grip Screws used "bushings", I initially thought 1911... but considering this "chart" shows them at .118" diameter, that is 3mm, and the 1911 uses .150" diameter threads.

Since I don't have an early P226 to verify, going from data I have investigated, they may be identical to Beretta M9/92/96 Grip Screws.

Beretta also used "bushings", and their Grip screws are M3-.5 Threads per MM pitch, which is "coarse", as Sigs other grip screw diameters are. Dimension wise they share the dimensions of the above example. The only verification I can't make is thread pitch, since not given for the Sig.

Anyone with an older P226, that can verify this, please respond! So this can be verified, and available for others use.


The "bushings" too may be identical, but one step at a time! ;)

If you could calculate the thread pitch, that would be great. It's not an easy task, but with the suspected "pitch" of .5 Threads per Millimeter and 3mm diameter. This should be the same size as a Beretta M9/92/96 grip screw, I have a Metric Screw Checker (Below left), that I can use to check. If you have a well stocked Hardware store locally, they should be able to check one of your grip screws, and give you its dimensions, with a tool like mine, or to the right.

Hi again. I got some measurements off the Sig P226 West German today. The good news is that the thread pitch is exactly like that of a Browning Hi Power. The bad news is that nobody knows the pitch of a Hi Power grip screw. From my measurements I got 16 threads in roughly a third of an inch which would put the thread pitch at roughly 45-48. Width is 3mm. Hi Power would have been metric as well being made in Belgium. Hopefully this helps. Let me know if you need more photos.

Thanks for the assist MaverickDMD

Basically the threads should be spaced .5mm, but I also have a Browning, so I'll compare their threads.

Great, the Browning Hi-Power uses the same 3mm-.5 pitch as the Beretta M9/92/96, the P35 on the left, and Beretta on the right.

The Beretta's head diameter, and length is closest to the Early P226...

From the info, you provided, they should. I've got a Browning Hi-Power, and Beretta 96, and determined they have the same thread/pitch, you advised the Browning Hi-Power had the same pitch as your P226.

The Beretta screws have basic same diameter "head", and threaded shank length, as the screw listed in the chart, so they should.

By the same token, should someone want custom Hex or Torx head screws, those for a Beretta should give them options.

By the same token, if any of the screw "bushings" get stripped or cross threaded, the Beretta bushings may also be a viable option. Of course their thread diameter and pitch would need to be verified.

The "replacement" grip screws for older P226s does come up every so often, and normally goes unresolved I believe. Hopefully this will give the owners, options. I've also posted the information on a couple of the Facebook Sig groups.

Sig Sauer P226 & P229 with Factory wood grips.
It appears from a note in Top Gun Supply's description for P239 Grips screws (GRIP-SCREW-6/#1200280), that they were also used with models using factory wood grips. SIG Grip Screw, Slotted Head - P239 - Top Gun Supply

Where should I search for P210 grip information? This walnut target grips, and a smooth, crisp target trigger. As advertised. to see if modifications to P320 are available
 
#26 ·
I guess you have me stumped. Are you wanting to see about adapting P210 grips to a P320, such as the AXG?

For P210 general inquiries, I would suggest starting a thread in the P210 Section, comparing actions to improve a P210s SAO Hammer fired target trigger to a P320's Striker Action is difficult, due to the completely different design.

Appreciate it, but one of the reasons it had been given "Sticky" status, as it along with other pertinent information may be readily available for members. Anyone is encouraged to add any pertinent information for Sig Sauer models, in an appropriate thread.

By the same token, if several members believe a current thread, may be of assistance to the membership in general, contact one of the admins with the suggestion. As always, insure the information is accurate, and factual, not just opinion... ;)!

old thread i know but all the good info here, same Q here. I have a P226 Elite w Rosewood grips.. i bought some Hogue Extreme screws, steel colored on the end but they didn't work with the Rosewood grips.

Gladly they did work with my P229, with Hogue grips.. they look nice :D

Here's a pic of the 3 screws I have. the smaller black screws w the red loctite on them came off my P229 Elite that came with stock grips. the same screws (red) also worked for the Hogue grips that are on it now but I went with the silver colored there.

The screw on the left, came out of the P226 w rosewood grips. Is there an easy button answer here for replacement screws for that gun? Is it the 1200312 I'm looking for?

As I mentioned in Post #24, use the P239 Grip Screws, for thicker wooden grips, just check to see if they protrude into the Magazine Well. Shorten them if necessary, so they don't interfere with the Magazine.

Since Sigs introduction of the P226 X-Five there are new Torx Drive Grip Screws, that take a T-10 Driver. These are actually the shorter P229 length with a 0.112" long threaded shank.

P220 Grip Screws are 5mm diameter threads, while the P229 Grip Screws are only 4mm diameter threads.

See the photo in post #1, which shows P226/P228/P229/P239 screws and their lengths usable on P229s.
