Why should I change P365 grip module

[Lo-Profile]

Honestly, why should I change P365 to Wilson Combat module. Are there any advantages. Does it make that much of a difference.

Yes it does, for the better for me.
I have a P365 a a P365xl (my EDC) and both have a Wilson Combat grip module, both have the tungsten weights as well.
Give better ergonomics and balance
Does limit some magazine choices.

I added the Wilson Combat grip module to my P320 as well, much improved over the standard P320

Frankly I don’t “get” the whole “larger grip” thing (XL, Macro). I KNOW they’ll be easier to shoot, but since in my experience the grip is the hardest part of the gun to conceal, why not just go with a larger pistol with the larger grip AND longer barrel/slide? Longer sight radius usually makes it easier to hit with.

Agree, bought my standard 365 on a whim. It was very easy to stash in the pocket of cargo shorts etc...
For me it turned out to be too difficult to shoot accurately and not a confidence builder for edc. So the choice was sell at quite a loss or spend $60.00 and have something that I can shoot. Last time I buy before I shoot.
