I see no difference between the .40 cal mags and 9mm mags...  I'm just wondering if they would interchange.

Guess theres only one way to find out

feed lips on the 40 are farther apart.

Yup... although they will fit in the gun and function , All the 9MM bullets May spontaniously spit out of the 40 cal mag

HK USP however...you can use 9mm in the .40 mags.

Yeah, well i can shoot .38 special in my .357 magnum revolver!.

Real post: Thats pretty cool, too bad it most likely doesnt bring the mag cost down.

You can put 9mm into 40 mags up to about 7-8 rounds and then the spring will pop them out. I tried it when I first got my conversion barrel and ended up buying real 9mm mags.

Even if they do work, I'd still stick with mags designed for the caliber if it's intended for self defense.

Except for .40/.357sig which works for me in a G32.

The .40 lips are a bit wider. I measured them with calipers one time. But they do pretty much work interchangeably. The round count holes are wrong of course.

9x18 and .380 magazines for the vz.82/CZ-83 are identical.

Just wondering: does this mean that someone could modify a 33-round 9mm mag for .40 S&W ?  AFAIK, nobody makes a .40 S&W 33-round mag for the Glock series.

If I owned a Glock and were inclined to try such a thing, here's the way I'd go about it.

1) Get a .40 round mag and measure the distance between the lips with a caliper
2) Carefully file the lips on a 9mm mag until they are the same distance apart.
3) Load it up and try it out.

Of course it will probably only hold 29 or 30 rounds of .40

sounds like fun, whose going to do it first?

I've got an old Sherer made 29 rd. Glock mag for .40 cal. It was temperamental about which angle it would work from, having used it in years.

I couldn't get 9x18 to fit in my p3at mag.  I wish kel-tec would just make a p918 or whatever they wanna call it.
