My very first consideration in buying a new gun, after I have done my research, is how does the gun fit in my hand? If it is not comfortable, no amount of gunsmithing (within reason) is going to change that. Once I find that right fit, I check out the available options such as sights, safety, etc. After I make my purchase, I shoot about 1000 rounds with the gun. By that time the trigger and other parts are worn/broken in and I can start to get the real feel of the guns action. That's when my gunsmith gets it. After dealing with me for about 25 years, he knows how I like my trigger and other such things.
Keep in mind that the more a gun gets used, springs lose tension, parts heat up and cool down and wear, and they are not like new. As such, trigger pull could lighten and lighten considerably. I used to have my triggers set at 3 lbs. but after shooting mucho rounds, the triggers lightened up to the point that they weren't safe (for me) any more and I had to have parts replaced/reset to bring the trigger back to a more comfortable 4 lbs.
A competent gunsmith can work a trigger to where you like it on most guns. Don't let a nice feeling trigger lure you into buying a gun that is really not what you want.
