I agree with leaving the pistol alone for a while anyway. Why make any adjustments or modifications until you have had 1,000 to 2,000 rounds downrange? Who knows? The trigger might turn out to be wonderful after it has had time to break in.
My take is the Smith is a good weapon but like the Glock, mad made so there will be issues from time to time. I like the way they feel in the hand as compared to the Glock
Sooner or later, all here and all shooters for that matter learn that all makes can be defective out of the box and ALL will crap out with enough rounds downrange.
I tell people when they ask me what to buy stick with these makers: Beretta, Glock, HK, Sig and Smith and Wesson. When they ask what "about" this other brand, I repeat my answer. I have my reasons and though quality is paramount, logistics and proven service record are also critical.
