This is true...and the other thing that I don't think that many stop to consider is that this pistol was designed as a self-defense (hence the SD designation) firearm, not a target gun. Yes, I know it's important to be accurate even at close range, and yes, I know you can still miss a man-sized target at close range, so that's why you practice to master the trigger
as it is, and insure that you have acceptable accuracy. In most cases, if you are involved in a self-defense shooting, it's going to be at close range...in fact, if the range is very far, it may become questionable as to your need to shoot.
I've gone back and forth over the trigger/spring kits, and I just don't feel comfortable with them...better sights, yes; extended take down lever, yes; even a stainless steel recoil rod, yes; but, for ME (and YMMV) I want to leave the fire control group stock. It will definitely serve my intended purpose, and I don't have to worry about inducing malfunctions or invalidating the warranty. Again, this is MY preference, and no criticism of anyone who decides differently is meant or implied.
When Bersa first introduced the BP9CC, I bought one...and it had the lightest trigger on a stock gun I've ever felt, even compared to my 1911s. If that trigger was over 3 pounds, I'd be very surprised...and it had no external safety. I traded it back in unfired...it was just too scary to carry.
