A PM9 isn't going to have less felt recoil or muzzle rise/flip than a G26, simply because there is less grip to hold onto. Personally, I have a hard time improving on the combo you have now. If anything, perhaps you could add a G19 for a bigger gun. It is still quite compact for its 15+1 capacity, and if you have difficulty controlling its recoil, perhaps an objective look at your shooting technique is in order.
