There is not connector that I am aware of. I did replace the striker spring in mine and it did make the trigger lighter. I think it is a great gun, and the aftermarket stuff will catch up eventually.
I found a great price on some Wilson Combat mags and a 1911 grip, and went to check out, only to find out they were charging $21+ shipping on $50 of merchandise that can fit in the palm of your hand. What a load of crap!! Anyone else experience this?
I've been with Liberty Mutual for 20 years now, and every time I try to shop, I find I am getting a pretty good deal. I might have to try USAA if I qualify, though - I heard you no longer have to be a veteran to get it (need to verify that though).
