I'm getting back into competitive bullseye shooting and have been using a Walther GSP .22 for the .22 stage. I had a Springfield Armory RO .45 and was using it out of the box for center fire and the .45 stages. For me, open sights are a struggle on the 50 yard line. I had my gunsmith do a great 3.5 lb trigger, full length guide rod, and install a Weigand mount to the frame for an UltraDot sight. Hopefully the 50 yard line won't be such low scores now.
