OP doesn't say if this is just for gaming or if it's a carry gun. Some places in CA still do CCWs I think, so it's hard to tell.
For gaming, like everyone else says just pick one and put in the time.
For defense, in CA of all places? That HK LEM he's pondering makes a lot of sense. Bolke's street trigger thread should be mandatory reading for anyone carrying a gun in a place where the prosecution can watch frame by frame and see if the shot broke before or 0.25 seconds after the threat became a non-threat because he dropped the gun or whatever. Yes, it will be slower. Match times if applicable will suffer. It also might keep you out of prison if your A-game isn't 101% on point when your number comes up.
I cashed out on striker guns and went all in on LEM after having a front row seat to the summer of love in 2020. Pistols are for timmy shit now. Revolvers and PCCs are for gaming. If we're talking about wiping the slate clean (again) and starting over (again) the use case is important. So is the year and the location.
