makes some slim grips that are well reviewed.
. My girl has a set of these, in pink none the less
, that were a tad bit slimmer than the stock ones.
Slim grips take a bit getting used too, I would agree with Cane on that. It does change how the weapon feels in your hand. If you can comfortably use a double stack, then I would think you would be able to handle a single stack with just about any grip on it. You might just need a DIFFERENT set of normal grips that feel better in your particular hand...
