With the groups I've seen you post with those two pistols, you'll do fine.
The "Open Pistol" and "Match Pistol" are both candidates for the P1. The 'Match Pistol' is open sights so that might rule out the LD on that one.
There is also the CO2 Pistol Match.
One other to consider is the Open Steroid match. Somewhere along the way it got labeled as a rifle match but was originally intended to be wide open, use what you shoot best, kinda thing.
We have way fewer shooters than we used to so join in a few....
