Are those Marinis BSA International MkIII by any chance?
If so, let me point out that they in fact use a separate mechanism to trip the main sear on the hammer.
And the lock time is not really noticed by any normal shooter when using a Set trigger. In fact the firing pin stroke can be shortened and a heavier spring used, something that would make a normal trigger too heavy.
There are no Olympic Free pistol shooters that do not use a Set trigger, and they shoot very long barrelled handguns with slow moving bullets (.22LR).
