+1 ........ very true ! Also Mike has pointed out that you have a few "misconceptions" about how the semi-auto works ..........and you might want do some more learning before buying.Anyway, all guns are compromises.
A few examples:
The ejection port size or placement has little to do with where a shell will be thrown from the pistol - the idea being you want the port placement & size to be such that the ejected casing "misses the port" on the way out.
The EJECTOR & EXTRACTOR control the direction of the empty casing as it leaves the pistol, in the best case scenario. Your problems with empty shells hitting you in the face has more to do with the "Ejector" needing tuning ........ more so than adjusting the port's opening.
Next, Trigger pull -directly- has no bearing on accuracy. It is true that accuracy is sometimes easier to obtain [ by a novice shooter ] with a lighter trigger pull. "Consistent" Lock-up of your pistol [ barrel to Slide ] is where you build the pistol's accuracy. It has even been postulated that the Slide's fit to the frame of the pistol has minor control over accuracy.
This being true with a pistol where the Sights, Slide and barrel are all one unit. So 1911's with a slightly loose Slide Fitment to the frame can still be quite accuracte!
Finally........you might be able to get a company like "Nighthawk" to build you a custom T-3  to your specs. but be prepared to lay out about 3 thousand dollars to start. Wait times on the build [ depending on what you want done ] could be as long as 6 months or longer.
Good luck with your quest ..........
