Experienced firearms owners, any suggestions for my next conceal carry firearm?

I currently carry a Glock 48. It is ALMOST the perfect firearm for me. The size is easy for me to conceal. The grip fits my hand perfectly. Fires beautifully after I've put 500 rounds though it.

Magazine capacity is my only complaint. Glock 48 comes with two 10 round magazines. I want a firearm similar in grip size and design, but with magazines that have more rounds.

Look exactly like the one I carry.
