P229 Locking Insert

ThnkFrst · 01-18-2013, 05:50 PM

Was recently doing a partial frame disassembly/cleaning on my standard model P229 chambered in 9mm. While cleaning the locking insert I notice some markings stamped on the bottom of the insert. They read: 229-.40/.357 Rev00.

Should the locking insert be matched to the caliber of the gun? Are there material/dimensional differences between .40/.357 inserts and 9mm inserts? Is this a case where the .40/.357 insert is just a little stronger and, therefore, suitable for 9mm chambering.

Would be curious to know what markings you P229 owners see on your inserts.

Did some checking around this weekend (Top Gun Supply, Numrich and others) and concluded that there are two different part numbers for the 229 .40/.357 and 9mm locking inserts.

TGS refers to a "1 dot" version for the .40/.357 part and a "3 dot" version for the 9mm. Photo shows dimples (1 and 3) machined in the top of the insert. Price is about $60 more for the .40/.357 version.

Called Sig this AM to get some insight as to whether the .40/.357 version is OK to run in the 9mm chambering but couldn't get through; those are some very busy folk I would imagine.

keep us posted on what Sig says; I'll have to check my 229 now and see if I have the same issue.

I just pulled my 9mm P229 apart and it says the same 40/357

My E29R-9-B has a BOD of 02/12. What's yours.

3/21/12 was my build date.

I'm no SIG expert so I am speculating, but SIG did standardize all calibers of P229s on the .40/.357 frame I believe it was a couple of years ago. Before that the 9mm P229 frame was more like the P228 one. Perhaps that standardization included the locking insert?

I'm no sig expert either, but that's what I'm speculating. Just trying to figure out why the .40/.357 insert is $60 more (as listed on TGS). Materials? Machining? Heat treat?

Because they are the only source and can charge what they want?

Actually, Numrich has both the 9mm and .40/.357 for the same price; about $134.

Hey! That's MY sig you're talking about. And my grandson is a redhead.

The cheaper locking insert might be for the older generation P229 that had the smaller frame. As someone else already stated, all the new ones likely only use the 40/357 version.
