Trigger Mech Difference Between SRV2, Sipriani, and Striker Pistol?

I want to make a gun using one of those trigger mech. But I don't know how they work or which one is better. Please Help!!!

Sipriani and Striker both use ratchet mechs and guide rods for the ammo, whereas SRv2 uses an original mech and sniper rounds.  The SRv2's mech is set up in such a way that the ammo does not touch the barrel, eliminating friction, thus its more powerful.

Oh cool. I'll probably use the ratchet system because it's pretty powerful and I know how to build one. Thanks.
