i agree 100% w/ the grip and stance concept, but running against custom 2011's is quite a challenge, i need all the help i can get. after i got the weight i sent it to bladetech, they did a DOH just for it, hth.
While many people seem satisfied with a trigger job, you may want to consider the new Fulcrum Trigger from GlockWorx. It is aluminum with adj. overtravel and pretravel and the trigger safety will depress all the way in when firing. It is supposed to be patterned after a 1911 trigger.
