4013TSW magazine floorplates, do flat ones exist ?

I'm considering buying a 4013TSW for a carry option, I've only seen mags with the finger extensions, are flat bottoms available or will another model floor plate fit. I'd really prefer a flat plate for concealablity reasons, any input is appreciated.

4013TSW is 9rd double stacker,4006 is a 11rd double stacker. Pulled one of each from my 'stash' and swapped floorplates,perfect mechanical fit(s). Visually the flat plate extends further forward compared to the curved plate.

Perfect, thanks so much for the information, I appreciate it. Now to find some 4006 floor plates.

I could be wrong but,
My understanding is that the 4013TSW is built on a 69xx frame.
The bump on the front of the 40xx mags is so they won't accidentally be inserted into a 9mm gun.
That being said...
I use 59xx bases on my 6906 mags for a flat base.
It might be worth a try... they should be easy to find.

Valid point, but since the 4013 is a .40 I'm thinking it should work. Plus, only swapping base plates hopefully doesn't present any issues.

Again went into my 'stash' and tried a 59 series flat floorplate on the 4013TSW mag. Worked perfectly like the 4006 floorplate.
So evidently all double stack 9mm and 40S&W floorplates are interchangeable,with the only difference being floorplate bottom shape of curved or flat.

Thanks again for all the info, and the work on your part. It's good to know i have a few options.

Now that the magazine issue is resolved I'll ask this, do anyone of the folks responding to my original question have both a 3913/14 and a 4013. I have a 3914 and am wondering how significant the size difference is between them.

3913 vs 4013 single stack mags are different.
4013 are thicker to accommodate a larger cartridge,4013 are longer to accommodate 8 of the larger cartridges(the mag 'catch hole' is in the same location as the 3913),and because the 4013 mag has an internal spacer along its' back inside,the mag is longer front to rear.
That spacer is removed to convert the mag over to accept a longer 10mm cartridge.
