That bomar looks nice. I have a 35 but run a similar set up. Heavy brass mag well, glockworxs tungsten extended guide rod, imsi 15 lb spring, Vanek classic trigger, lightened striker, heinie rear, warren FO front (though I have a set of Dawson adjustable to put on it), KKM barrel and Dawson +5 extensions. Though I can only get 20 in one of them the rest are 19.
It shoots great. I think you would be happy with a similar et up.
