I practice nearly exclusively with my EDC's - an XD-s 9mm, and a Hellcat. They shoot nearly identically with the only difference being capacity, and I have to watch out for the mag release on the Hellcat since it'll drop the mag with just a tickle from my support thumb where the XD-s I have to make a conscious effort to hit the release hard enough to drop it.
The "why" was driven home to me about 2 years ago, when I was at the range with a buddy. He has a full-size Kimber 1911 (he doesn't carry, it's strictly for home and range use), and wanted to try my XD-s. We all know the compacts are snappy compared to a full-size, but he was watching me put everything inside the 9 at 10 yards, firing once every half second or so. He wanted to try. So...we switched.
He...was all over the target with my XD-s, not prepared for the muzzle rise, not sure about the "rhythm" of when it would be back on target, and not really familiar with the bladed trigger. He was shooting relatively conservatively, probably a round every second or two - not dumping the mag by any stretch.
I...put the entire mag through one (admittedly ragged) hole, firing his (relatively speaking) incredibly solid and stable 1911. First couple rounds were 1/second, but after I learned the rise and rhythm...I was the same pace as my XD-s.
I cannot imagine practicing with a fullsize, then thinking you can carry a compact/subcompact, and expecting it to all "work just the same". About all that "works the same" is "one-pull-one-bang".
