I think the important thing is to have the same trigger pull and action style. So, for you, multiple Glocks would be perfect.
My carry gun is a S&W BG380, which is double action only, while my home gun is a DA/SA Taurus PT92 with decocker. So, I my PT92 is kept in DA mode. And, I never use the safety, so I can grab any revolver too and expect the same things to happen: grab gun, squeeze trigger, go boom.
