I have been reading over some old TFL post (when I should be sleeping) regarding barrels.  Did the early production guns have different barrels and what would be the distinguishing marks (9mm)?  I also read about early Walther strikers breaking which they replaced with stronger units.

My 9mm is a KI and has the most recent trigger.  Just wondering if anyone knows when and if they redesigned the barrels.  Are the 9mm and .40 striker assemblies interchangeable?

Anyone have feeding problems with the 124 gr. Gold Dots?

Thanks

Darn, misspelled barrels in topic header, ugh, it's late.

I know they have changed the crown from rounded to squared on the barrels. This change helped accuracy immensely.

P88,

What should I look for to determine if mine is sqaure or rounded and do you think my KI is the older version?  I'm assuming the crown is at the end of the barrel?

Anyone know what happened to Herr Walther?

Thanks

So can anyone differentiate between the square crown and rounded? Has anyone ever seen a rounded crown?

How about a definition between rounded and squared?

TY

CKW,

I'd take a picture, but I got rid of my two P99's that had the rounded crown. Basically on the outside edge of the crown of the barrel Walther rounded the edge. Now they don't round it anymore it is more like a 90 degree angle or cut square to the barrel.

P99,

What year of manufacture were the ones that you got rid of? Did they have the split trigger? I'm hoping my KI doesn't have the rounded barrel. I was unaware of this when I got it. I know it has the most recent trigger variation. If you were to compare the square with the rounded would it be obvious?

Thanks

Both of my P99's were .40 caliber, so they didn't have the split trigger. And yes it would be very obvious that you had the rounded barrel crown.

I wouldn't worry about it. Both of mine shot really good, I just noticed a little bit better accuracy with my newer P99's and I attribute it to the squared crown. But it wasn't anything to really get that excited over.

I do have some pictures on my computer of those two guns. If they show the barrel to where you can see the roundness, I'll try and send them to you.

Maybe Extremist can help out here, I think he has an older P99.  Or someone else with a KI date code.  

Does anyone know what year they went to strait cut?

I think /dev/null has a KH.  Maybe he can check to see if he has the rounded crown or post a pic.

I pick up the KI on the 10th so I wont know until then.  

It could be another interesting fack for the FAQ.

Thanks P99 for your info- I know someone here has to have a KI though...

CKW,

I've not had any feeding problems per se with 124 Gold Dots but failing to fully chamber is the best way to describe it. First generation GD 124s had a long shoulder on the bullet that interfered with the short throat of the rifling preventing the cartridge from fully chambering as the bullet engaged the rifling prematurely. Current generation Gold Dots work fine for me. I also have an extended SD threaded barrel that is cut with a longer throat and works OK with the first generation GDs - I assume to make them more receptive to longer, heavier subsonic bullets.

here's a picture of my KI Walther (German made). I believe it's rounded (never had the chance to compare though !).

P88,

Can you tell if that is a rounded crown on the picture above?  It looks like the crown on my AC .40.

Have you actually seen a rounded crown on the 9mm or just the earlier .40's?

I can't tell from the picture. I'd also have to find an old 9mm to tell because I've only owned .40's until I recently purchased a 9mm QA 2 months ago.

So no, I don't know if the 9mm's had the rounded barrel.
