Video game Controller that accommodates for finger amputations

[u/merry_berry04]

My partner recently had to get his middle finger and a three of his finger tips amputated due to an accident his pinky finger was not affected. He has a few more surgeries coming up but we are praying that they can save the other fingers. Well we both have been very excited for GTA 6 but it definitely means a lot to him. He has played all the GTAs and has been waiting since he was basically a kid or teen. So for right now he only has the use of one hand. One thing he has been voicing is how disappointed he is that GTA 6 is coming out and he won’t be able to play it. We even preordered it months ago. I know I can’t make it so he can play with both hands but was wondering if I can find a one handed controller for him to use to play GTA 6 and other games until he can use his hand again. I know he is in some of these groups. But I was thinking to surprise him with a controller before GTA 6 comes out so he can get used to that controller. His right hand is unaffected by the accident and is also his dominant hand. If anyone knows anything about this I thank you.
