The only interesting development has been the convergence of all the major players on the Glock-style striker fired system, due mainly I think to the consistent first-round trigger pull which is a big deal for practical shooting, and a cultural shift towards accepting the... shall we say, less idiot-proof design. Although, everyone except Glock seems to agree that it's a bad idea to require a trigger pull as part of the takedown procedure.
