Howdy hamonrye,
One of the sweetest 1911s I've ever fired was a Springfield 9mm. It
had been tuned up a bit, but 1911s in that caliber are a real pleasure to
shoot.
The "problems" usually stem from the cartridge overall length not being
compatible with the 1911 platform, but these issues are easily solved with
good magazines.
The other problem is a little more real with the new ILS system on the
Springfields. The mainspring is a short, heavy affair...with a load rating of
about 28 pounds, and being short, the load stacks more quickly than a
longer spring of the same rate. The combination of the heavy mainspring and a standard-for-the-caliber/gun recoil spring makes the slide a little
sluggish in recoil, which can cause some ejection problems until the
mainspring takes a good set...and sometimes they require a lighter
recoil spring to balance things out.
My advice would be to swap out the ILS mainspring housing and the internals for a standard set-up and go. A 12-pound recoil spring and
a 21-23 pound mainspring works well. You'll need a standard mainspring
cap, spring, and cap retaining pin to switch over...and the right way is to
get a standard mainspring housing too...though the standard internals
will probably work okay in the ILS housing.
Not a very expensive or complicated swap.
Luck!
