Utilize TMC magazines in your Valken/Milsig M17 marker. This magwell uses "ball on deck" system to make up for the collarless mag on the M17 which was designed to use collared mags. This means the last ball in each mag will not feed into the chamber, and instead be held in place by a rubber detent during mag changes. The first mag will feed 1-2 fewer balls, but each mag afterwards will fire all 20 rounds.

The magcatch is semi ambidextrous, allowing you to use either trigger finger. 

No modding of the mags is required.
