There is also another option in obtaining what you want called "Collective Bargaining". It may cost you some jewelry or the choice if where you take vacation or some such thing, but it may get you another pistol. Definitely do not do the "Buy and don't tell"! Woman have a built in Psychic Radar that tells them when the game is afoot, and you will be in trouble for sure, when discovered! It will not be a matter of IF, but WHEN.
Of what you have mentioned, I would get rid of the Glock 22, but only because I do not particularly like Glocks. Of the Plastic Pistols, I'm partial to the Springfield XD's although I don't own one, as yet. Been thinking about a new Witness P Carry in .45 ACP, but have not yet succumbed to the temptation, as I'm quite happy with what I have now. (Unusual, but true.)
Any small .40 will be a handfull to shoot. Perhaps you would be better off with a full size .40 CZ75B or Full Size Steel .40 Witness, if concealment is not a concern.
