drck1000,
I got the tungsten rods for the SIG P365 (& P320) today. Rods are really heavy for their size.... I think they weigh more than lead.
True to the reviews, the rods were loose in the slots, so I wrapped them with black washi tape (electrical tape or masking tape would work also)
so they wouldn't rattle.....
I think with the rods and a full mag, the P365 weighs like a "metal" gun, like maybe a compact 1911.....
The last picture is my P365 with the Wilson Combat grip module and the extended mag.
(I think the WC grip makes the 365 real close in size to the HellCat)
The WC grip, tungsten rod, and extended mag are good for Kokohead.
I would revert to the standard SIG grip and short mag for CCW though....lots of carrying and not shooting......
