So to answer this question: does the zev pro compact magwell work with 10 round magazines....
Answer: no
BUT if you modify the base plate it will...
What I did was take off the OEM base plate off of my factory glock 10 round glock 19 magazine, took some sand paper and shaved it down a tad(the base plate). I first used 220 grit then 800 to smooth it.
works fine. magazine seeds in properly and it took me 5 minutes.
