As others have said, larger service sized pistols are almost always easier to shoot than a lighter weight compact pistol.
For most shooters that means better accuracy, better rate of (accurate) fire, and a greater likelihood they will shoot more often, with a higher levels of proficiency as a result.
In my experience way too many people get hung up on all the wrong things, encouraged by "experts" who make money of product promotion and teaching a long series of tactical pistol and self defense courses. Proficiency isn't something you can buy by getting "the best" pistol, or by attending a course.
Get (or keep using) a pistol that fits your hand well, meaning one you can grip in the holster, draw and bring to eye level with the sights in view and more or less aligned. Then practice with it, drawing or bringing it up from a low ready position into your line of sight, placing the front blade on target, and then pausing to align the front sight in the rear sight, and then maintaining that sight alignment while you press the trigger.
It's slow initially. However with repetition the muscles in your hands know exactly how they have to tension in order to align the sights and at that point sight alignment for all tactical pistol purposes becomes an automatic and unconscious act. Your pause then gets shorter until it only serves to verify the front sight is on target and the target still needs to be shot.
Unfortunately way too many people try to fast forward to shooting fast without ever mastering the basic essentials of grip, sight picture and trigger control.
When that happens, these shooters start looking for a "better" pistol in hopes of providing an equipment solution to what is really a skills deficiency.
It's not the guy who gets the first shot off who prevails in a self defense situation, or even the guy who gets the first hit. It's the guy who gets the first effective hit.

Lighter weight isn't all sunshine and rainbows. There's never a free lunch, and a pistol or revolver that is small, light, and easy to carry almost always has downsides when it comes to shooting both accurately and rapidly, especially in a substantial cartridge.

Carrying a 35-40 oz pistol comfortably all day long isn't difficult, it just requires a well made concealed carry belt and holster.
