S&W Grip Adapter for N-Frame - Fit Issues?

[CKPOMEH]

Hi folks -

I just purchased a S&W grip adapter for N-frame but the fit is not as snug and tight as I was expecting (I have a K-frame with a Tyler T grips and they are very snug). Can you take a look at the attached and let me know if:

1) Yes, those are supposed to look like this, or
2) Something is off here - the shape may have changed over time, I may have installed it improperly, etc?

Thanks a bunch in advance!
