In about a year I will be going to police academy. Of course some ignorant buffoon established a rule banning single actions. So I bought a sig p220, (which I love even though its as ugly as margret thatcher.) As it turns out, they supply free ammo if you have a 9mm or a 40. A 9mm is out of the question. I don't believe compromise between weight and power is a good idea, and I'm not a small framed woman working for the FBI, so I don't want a .40. I would take a 40 if it could be converted to 10mm and it was at least the size/weight of my 220, particularly if it could save me all that money on ammo. Keeping in mind I absolutely don't want a Glock or a para LDA, whats a good option for a reliable DA/SA convertible between 10mm and 40 S&W?
