V9 SA for the win! So I guess "DA/SA" but hold the DA....
I'm not sure I know what "worked examples" means. I have 2 SA/DA H&Ks and carry both in Condition 1 (cocked & locked). That's how I trained initially. I only got a 1911 later.Off the shelf LEM triggers are simply deliberately crippled in favor of “safety” for indifferently trained institutional users. Quite different than the still-crippled but more usable, fettled “Light LEM” triggers used by (fewer and fewer) enthusiasts.
Ironically, most shooters are not trained well enough to carry the best shooting trigger options- single-action striker of the VP9, or cocked-and-locked SA on worked examples of the USP/P30 series.
But most do.
