I am having some reliability issues with my 9mm mags
my gunsmith says the back inside lip measurement should be .340
and the front inside should be .350

Well I go .350" back .355" front on my 2011 mags so it sounds like you're close. What kind of problem you seeing?

Perhaps a fun project, but I consider mags consumable items. When they stop functioning properly, I get new ones. In the event you haven't seen Hilton Yam's video on 1911 mags. He talks feed lip dimensions, but he's talking .45 Auto mags.

My comment,... use those measurements as a guide, but, adjust just ONE until it functions as you like.

Then,... USE IT!

And when you are convinced you found your solution,... adjust the other nine accordingly!
