Gave my daughter a pink frame stainless steel slide Ruger LCP as a wedding present.
She shoots and carries it regularly.
She loves the gun
I sometimes carry a LCP II as a backup gun.
As for 40 S&W.
Got into the round when it was all I could find on the shelf during the last two ammo shortages.
Actually shoot it well, and with some guns can switch to 357 Sig
Recoil is fine for me except in super light micro pocket guns.
Around 20 oz. is where I prefer 9mm (Ruger LC9s Pro).
My friends Walther PPS 40 was actually uncomfortable for me to shoot 
My PPS M2 is in 9mm
My Hk P30 40 is a tack driver.
And preferred CCW is a Hk P2000SK 40.
Albeit it's usually sporting an OEM 357 Sig barrel and hot Underwood ammo
