I personally think it's critical to maintain identical platforms with every gun you carry. This post has revolvers and DAO semis. Both have the same trigger pull. I would not routinely carry Glocks and revolvers.
The reason I say this is for a long time I carried a Sig P229 DAO at work (40cal.) I'd practice extensively with it and get pretty good. Then off-duty I'd carry a Glock 27. Switching back and forth was problematic in fast shooting. I'd either short-stroke the Sig's longer trigger or slap the heck out of the Glock's shorter trigger, depending which gun I'd been training with most recently.
KISS requires the same platform, same trigger in my opinion. YMMV.

Going forward I will be limiting myself strictly to the M&P 9 and on those occasions when I can't conceal an M&P 9 an M&P Shield 9mm.
