It must definitely be an individual hand/fit issue.
I've got a SMC-918, which is an FEG made gun from Hungary that is basically a PPK knock-off. Not nearly the same quality pistol as a revered Walther, but a decent carry weapon in 9mm Makarov. It fits me beautifully. However, my buddy, who is an accomplished pistol shooter cannot make the gun fit into his hand for anything. Just a matter of fit.
