Sure, at 3 times the price!
No. I used STI edge should cost you around $1800. I probably have more than that into my glock.
This.
Been there done what you did. Buy an Edge and save the wasted time of going with a glock.
Base Gen 4 35 $650
Lightened Slide/Work $3-500
Trigger and related parts $200 plus
Magwell $85+
Sights $75+
Barrel $175
Didn't include base pads as they will be an expense for either gun. I went the route you are trying to go. I, like darkvibe, probably had as much or more into my glock than what I spent on my nearly new edge. You can be competitive with a glock but the 2011 is simply a better platform for Limited.
That being said, if you are dead set on going glock, get the base gen 4, prob would go Zev slide, I really like the agency arms flat faced trigger and a Taran Connector (have it on a carry gun with factory connector), the magwell of your choosing and the Taran Tactical sights and basepads. A good trigger to check out with a flat face would be the DK idp flatline. I had one of his kits and like it but preferred the flat face, he didn't offer the flat face at the time. KKM barrel as well.
