You can buy dedicated 45 lowers that take different mags. I forget the brands and there are other uppers out there.
I wanted to use my INGO lower and I did not see many other magwell adapters out there so that was the main reason I choose to use this brand and then after dealing with Rudy I was very happy with how he took care of the transaction.
