PanBaccha, his gf doesn't know how to shoot yet. He's trying to teach her how.
A small, lightweight pistol in a service caliber, with a heavy, long trigger pull is probably not the ideal introductory gun.
The LCP might be a good choice for a carry weapon, after she learns how to shoot with something more new-user-friendly.
IE, grip that fits her hand well, good trigger reach, reasonable pull, fairly high weight to power ratio to keep the recoil down, and good sights with a decent sight radius.
Sort of like a S&W Model 18, Ruger Mk I/II/III, Browning Buckmark, etc.
