FYI ZEV Technologies has a sale on their products on their website. I am not sure how long it will last but the prices I looked at are cheaper than wholesale pricing. I just bought a Glock 43 for my wife and one for me and I wanted the drop in trigger. It was little over $100 wholesale from my firearm distributors and ZEV had it for $75 on their website. I am fond of their triggers and the drop in are easy to install.

I got a few of their mag extensions for the magpul G17 mag that normally sell for $40 for $10 each. They have some good prices on G17 slides as well.
