I was told that the old school baffle type suppressors have the least first round pop vs the newer mono core types.

That said, the blast baffle cracked in my GemTech and sent it off for repair. Evidently they no longer use the aluminum baffles and are replacing mine with the mono core. At the cost of $269, I'm gonna find out if there is a difference if they ever get it back to me. How long does it take to dump the old baffles out and screw in the new system? I do not recommend GemTech after this mess.
