One of my Renegades is the same lock you suggest is faster. I personally can not tell the difference as both of them are fast. Besides, I seldom concentrate on the lock, instead working on sight picture. Any action can be "tuned" but there is only so much you can do to make them equal.

Now I have flintlocks that I consider a very fast ignition. Faster then my sidelock ... who knows. But if that is all they are basing their problems with a striker type action on an inline, like a White, Black Diamond, CVA Staghorn, Knight Wolverine, and the list goes on.. they are grabbing for straws as they have no base to their arguement.
