Sir it should be 13rds same as 9mm. For the 9mm round was made from the 30Luger brass . They just took the shoulder off and tapered it to 9mm. It was a improvement in stopping power the German Navy&Army wanted. Hope this helps,best Jeep, Bill you going to the Medina OHIO show this weekend 11-10,11-12?

 

Just don't know- putting the two side by side the 9mm luger looks significantly wider all the way up. I do appreciate the answer though.

And yes, I plan to go to Medina with a buddy Sunday (second time there for me) and maybe Akron the following Sunday if my buddy wants to go. I have too many guns (mostly FN/Brownings) and don't dare spend any more on them as I just retired and paid the house off (that's why I'm so broke) but my buddy's into AKs, Maks and Saigas and always looking for parts. It's also an esoteric crowd at gun shows. At the Berea Fairgrounds one a few weeks ago I tried to see how many FN/Brownings I could spot. I actually came up with about 10, mostly Hi-Powers. Haven't been to many gun shows yet but that's my high on the FN count. At Medina I saw about two.

Definitive answer: standard BHP .30 Luger (7.65x19mm) magazines and 9mm Luger magazines hold the same number of rounds; 13.

 

Well, that's it then. Strange- when you compare the 9m to .40 cal- in the same size gun (except for the slide of course) the mags will only hold 10 rounds in the .40. The 7.65 Hi-Power was probably so rare Mec-Gar never made any hi-cap mags for the 7.65 like they did for the 9m (15 rounds in flush fit).

Thanks for the info.

The 40sw is not tapered and is .40 ,(10mm)on the front end even though the base is the same as the 9mm. The few thousands of difference on the front end limits the capacity a few rds with the 40sw compared to the more slender front end of the 9mm and 30 Lugar. In the Hi-power I allways stick with flush 13rd. magazines for reliability. The extended mec gar's in 20 are good. Bill seems Hi-powers come and go at the shows. I seen many at the OGCA Show IX Center in Cleveland a few weeks ago. Even a Sultan of Oman tagent with shoulder stock. A few Inglis,FN,Nazi,Browning and a lowly Indian copy.

 

Haven't been to the IX center ones yet. Am trying to attend all of them even as far out as Niles as some dealers don't do them all.

Have a great holiday season.

A little explanation for the sake of clarity is in order.

Basically, the .30 Luger cartridge case is dimensionally identical to the 9mm Luger EXCEPT it is tapered to accept and hold a smaller .30 (versus .355) bullet. The .40 S&W cartridge is essentially a cut down (shortened) 10mm cartridge case and uses a 10mm bullet. That said, the magazine built to hold 13 rounds of 9mm will accomodate 13 rounds of .30 Luger given that the significant outside dimension (case diameter) is the same. The .40 case having a proportionately larger case diameter than the 9mm/.30 Luger takes up more space. Hence, 10 of the former take up as much space as 13 of the latter.

As for magazines feed lips, there are several things they do:
1, they hold the cartridge in the case so that it doesn't come out until 'pushed' out. 2, they hold the cartridge in a correct position to allow and promote efficient feeding (understating - facing into the chamber). 3, they actually 'guide' the cartridge into the chamber as it is being 'force-fed' into it by the slide moving into battery.

That being the case, the shape, geometry and tolerances of the feed lips becomes the product of some complex (far too much for my feeble mind) physics and mathematics that are unimportant to us, the users, so long as they are correct.

 

I appreciate that knowledge. Sounds like you've been around semiautos a long time. I have to admit my Browning Hi-Power Practical bought in 2009 was the first semiauto I bought, wanting to give them a fair trial to see if the modern ones were as reliable as revolvers (I have a few choice snubnose .38s). I am happy to say FN/Brownings at least are- I'll never use a revolver as a primary home defense weapon or CC again (but will keep them around for backups just in case).

Last gun I bought (and probably the last period as I have too many and just retired, drastically cutting my income) was a FN Hi-Power .40 cal SFS, just months ago, and it's a honey. The recoil isn't noticeably more than the 9mm to me. The black plastic grips were horribly cheap- not even the finger sculpted ones like some Hi-Powers have- but a set of Hogue kingswood grips makes it look like a different gun.

My mistake in bullet size is I have some 7.65mm rounds which fit my FN model 1910 and it isn't the same bullet as a .30 cal, is it? More like .32 cal APC. That's what I was comparing to the 9mm.

Again, thanks all for the knowledge. That's what's so good about this Forum.

Best,
Bill

 

Bill,
Here is a little cartridge info for you:
The 7.65 Luger was developed in 1898 and based upon the Borchardt and a number of other 7.65 cartridges. It is the parent cartridge from which the 9mm Luger was developed.

Dimesions:
7.65; Bullet Dia= 0.309in, OAL= 29.59mm, base Dia= 0.391in. 9mm; Bullet Dia= 0.355in, OAL= 29.69mm, base Dia= 0.391in.

And, you are right. I've had some exposure to semi-automatics - and a few other things too.
