thank you for your reply and post, the 5.7x28mm is to big in size for my wife, but you caused me to read up on it and now i want one. we are still looking, the p22 felt good in her hand. da teacha is a very apropos name, i read some of your posts, i felt ashamed, when i read your advice to bunnywabit about her car purchase, i am trying to run mine until it falls apart and i am weakening, i think it will out live me.thanks again. pat

i am ashamed to write that i have no idea what a 5.7x28 round is.
