Hi-cap 10mm

Most likely Glock magazines will be your best option. They make an extension for Glock 21 (45ACP) magazines that almost doubles the capacity, but I don't know if it will also work for G20 10mm magazines. Den posted a link that shows the extension on a 10mm magazine.

Hey TSP if you have a Dremel for hogging off the initial mound of plastic, and a fine flat file for cleaning up the edges, and a vise for squeezing the spring, this can all be done to one mag in less than 20 mins, faster as you learn the method. The people selling these for $100 dollars are cashing in big time. Here's mine on a G40MOS 10MM with 9" lonewolf barrel. G20.4 Mag with Kriss 45 extender. Friends dubbed the frankin glockzilla, functions fine for a range toy.




Oh by the way, if you get a gen 4 frame, be sure and get a gen 4 mag. 1's 2's and 3's however can use any gen mag.

9" bbl......waaaay cool.  Guess I need to stay away from gen 1 too.......something either on youtube or Mectech concerning something to do with the frame rails being plastic or combination plastic and metal that causes problems getting the Mectech to lock on, but I'll look into it further when I'm readyt to build it.   Thanks .

Coolest thing I've seen so far today.

I have a new mech tech 10mm with a 2011 SV bottom. With SV 140mm magazines,  Dawson bases, and SV competition followers I can get 19 rds. In the mags.

Very nice Glock you got there. Practically a carbine. I've never hunted. That would be a true deer bane.

My Mechtech 10mm just landed as well.  I run the 1911 platform and this one joins my 460 Rowland version - yes, I like my substantial pistol caliber carbines.

I dedicated a Rock Island Armory 1911 A2 (their doublestack) to semi exclusive carbine duty.  I am running 16 rd mags as 17+1 for 10mm with 100% reliability.  This is plenty for me, but there's more to be had.  How many rounds will the Dawson 170mm manage?  It fits.  Dawson also has extended floor plates for the mags I already have.
