I have the 43X, 19X, and a 40 MOS with a DPP RDS. I’m thinking those 3 pretty much cover all my needs for concealed, open carry and home defense in pistols. I’m also thinking a G30 or G36 would be a nice addition for me. I’m a 357 Sig fan too, but Glock hasn’t made a single stack in that caliber yet. Maybe I should add a G27 to my collection.
