I’m trying to compile some data to see when Walther switched to the notched locking block. Might be an interesting tidbit for the Walther FAQ page.

We know that some AC date coded P99's have either. Just interested to see possibly around what serial number they started.

A simple spreadsheet could be compiled which could show a trend. Showing just the first 4 digits should be sufficient without giving too much away.

I'll start.

P99 .40 AC 4158, No Notch

P99 .40 AC 4141, Notch

 

[M700Police]

9mm Military model - AC 0502, has notch

Can someone post pictures showing these two different parts?

Thanks

P99 .40 AC 4139, Notch

9mm Military AC 0498 notch

Thanks guys, that’s great- keep them coming.

Anyone have a post 4158 with a notch. We may be stumbling on something. Walther possibly is reverting back to the original design on the latest batch?

9mm Military, AC 0511, Notch (before repair)

I'd also like to see pictures showing the difference between the two. I'm not quite sure which one I have.

I guess I should've googled it before I asked for help.

For anyone else who is wondering about the 'notch' I found this thread over at Park Cities Tactical.

Note, the 'notch' is not the crack that you see, rather the notch that you see below the crack in Mercutio's pictures.

Now that I know what the notch is:
P99 .40 (black) AB 4129, no notch

Hey Mercutio, our guns are brothers! P99, 9mm, 0508, notched.

 

[CKW]

Hmmm,

AB 4129, No Notch .40

AC 4139, Notch .40

AC 4141, Notch .40

AC 4158, No Notch .40

It Appears all of the Military P99's 9mm's have notches, at least as early as AC 0498 and as late as AC 0511

I can see a trend with the .40 but not the 9mm.

This is good stuff.

I thought you were only interested in date code "AC" P99s.

My "AB" Military, 9mm P99 has no notch.

You know, now that you mention it, I can see a family resemblance!

AC dated 4163## 40 Military German Proofs
NO notch in the locking block.

AC, 5124 no notch. P99 9mm Military.

German P99 .40 all black 4166##. It has the notch. Seems to be random.

An engineer at Carl Walther (in Germany) gave me the scoop about the notched locking block. I added this information to the Walther P99 FAQ (as IX-19). See: http://www.praxagora.com/lunde/WaltherP99FAQ/IX/19.html
