Thanks guys! I bought it used with approx 100 rounds through it, it is serial RC1xxxx.
Ill read up on the new user guide, and look into the lakeline upgrade.
I bought a few types of ammo to test at the range that I've read others had success using (avoiding the white box winchester flat tips & fiocci)
I'm looking forward to trying it out! All I've had time to do so far is a field strip and clean it, and rack the slide a ton of times
