I have a USP9F, I don't really want to extend my grip, especially for CCW. Can I use a jet funnel mag for a second mag without using jet funnel or something like this?

Just like Glocks can, like putting a G17 mag in a G26?

Yes you can. You will just have a huge gap where the jet funnel would be if you were using 18 round mags.

Where the only problem in reality is aesthetics right?

Yes, it will function fine.

But the jet funnel isn't just a mag spacer. It funnels mags in for easier/quicker mag changes.

Removal of a jet funnel takes maybe 5 seconds. It takes a 3mm hex key to unscrew just one screw, and boom you can use the regular mags again.

The only thing you lose is the lanyard loop.
