cz97, parts easy to come by
HK Mark 23, hard to get and hard to get parts
HK45 easier to find, can put in the right backstrap to really fit your hand, parts a little harder to get.
That cz97 is pretty hard to beat for what you are looking for.
Not many around so not a lot of guys have had experience with them. Its an awesome pistol.
Any Sig will work as well. The P220 is a very very nice choice, easy to get parts. grip is a little deep but a litte skinny, you can always put a hogue slip on that will make it feel better.
