My last purchase was a Rock Island 3 inch CS Tactical. Although not a 9mm like you want the very first thing that really impressed me was the factory trigger. All my other 1911's which all cost considerably more than the Rock Island EXCEPT for my TRP had stock triggers that were mostly not all that bad still ended up getting what I refer to as my standard treatment to make them acceptable to my standards. The Rock Island still to this day I have never touched the trigger and don't intend to because it's simply not necessary. To be absolutly up front, the average new 1911 I don't care who made it can and most likely will vary quite a bit from one trigger to the next even in the same model and manufacturer. These latest models from the Phillipines have been pretty much holding some of the best factory trigger pulls short of a $1000.00 or MORE factory pistol or the higher end custom such as Wilson, Ed Brown, Les Baer and many others. Their slide to frame fit on the ones I have had the pleasure to try has been nothing short of VERY impressive for the price. To make a long story short there are many 1911 smiths out there that can improve your stock trigger easily and in expensively than you might think. Some charge WAY to much for a really simple job. I know this because I built my first 1911 at age 18 which took me almost 2 years to get it right but in the process I have learned much about the platform and do all my work myself. If you have no experience with the proper operation of the 1911, have someone qualified to do the trigger work. Finally with the 3 you mentioned, I beleive you will probably be happy with the stock trigger. Best of luck to ya.
