I have about 400 plus rounds through mine now and no issues at all with knuckle bashing. I have tried all three backstraps for the grip and even with my big hands the small one gave me the best "hold" on the gun. Some people I have noticed just like to choke-up on their grip, my brother does this bad and he lost skin to a Glock slide.

Well...I think I just learned I've been improperly holding my pistol since I started shooting (although that was only a few years ago). And I think I know the reason why.

My first pistol was an SR9c. Still have it and still love it. However, that being the first pistol I shot frequently, the grip tang is so contoured or rounded on the top corners I never had the thumb knuckle bite because my knuckle easily cleared the corner even when rotating it a little for further reach with my trigger finger. Now that I have a RAP9, it is more squared off in those areas which causes it to beat up on my knuckle.

Headed back to the range tomorrow to see if this fixes the problem!

I'm three sessions in on a 5000-round endurance run on a full-sized 9mm version.
Roughly 150 rounds first session for accuracy, 450 rounds on a second session load & fire, and two days ago 1000 rounds load & fire.

The pistol frame is wider at the upper rear than others & that left corner does make contact with the base of my thumb if I use a high-thumb hold, which is not the way I normally shoot.

I'm forcing myself to deliberately shoot thumbs up in finishing the run to see if that's really an issue for me.
So far, even through the continuous 1000 rounds session, using the insert that came on the pistol, the worst it did was a noticeable minor abrasion on the skin.
Not really uncomfortable, did not draw blood there.

If I were to be shooting it the way I normally do, both thumbs locked down, it wouldn't even do the abrasion.

I have the RAP 9mm and never had that issue. You could try with the small backstrap to see if that will allow you to adjust your grip as others have mentioned while giving you the most reach on the trigger

For me, my RAP 45 is the smoothest shooter I have out five and has never given me the first rubbed thumb knuckle. But it dose my wife, she doesn't care to shoot for that reason.

Three more cases today, I'm 3000 rounds in now, halfway done on the endurance run.

The base of my thumb is very sore, but no scrapes or abrasions there.
Did draw blood in about the center of the web, looks like from the upper edge of the grip insert, NOT the frame corner.

All of the 1500 today were fired from a thumbs up hold.

Incidentally, still chugging, bone dry.
The initial Breakfree lube just before starting the initial shooting burned off quite a ways back.
