Nice!
Lol "rip ... up" and "IDPA Match"...
Adjust the rear gently - move them right if you want the bullet to impact slightly right/left if you want them left.
Leave the FS alone - it should be staked.
Might want to check if the the gun already has the optimized trigger bar in it, etc...
13# spring is very nice - 14# last pretty much forever. 12# will wear out and lead to light strikes after ~6/7K?
Check your mags! The Beretta shockbottle basepads are for Beretta magazines.
The MecGars might need a slightly different base bad (SP01 pads or CZ75, I can't remember which I have...)
