1. Has no MIM parts. Let's not turn this into a MIM debate. I've read the pros and cons of MIM and would prefer something without MIM.
Err, well, if you want a pistol that is 100% MIM-free you'll have to step far and away above a Glock budget.
You're talking about needing to do 1 of 2 things:
a.) Special order from Wilson/Baer/Fusion/C&S, etc., or
b.) Source the MIM replacement parts for pistol Xx, and have those MIM parts swapped out.
Either way, not sure of how/where you figure Glocks are MIM-free pistols?
