When I switch from the 1911 to the Glock in IDPA, I stick with one or the other for dry fire, live practice etc. it takes me a few weeks to get comfy with the Glock, but the 1911 is always like coming home. I shot my first match back with the Glock last saturday, after about 3 weeks of practice, I never felt like I was in tune with it and thought I shot pretty poorly. When the scores were posted I finished 2nd overall out of 72 shooters. So sure you can shoot anything well, it's as others have said, when you feel "lost" stick to the fundamentals, front sight press will work when all else fails.
