I’ve been on the hunt for a carry case for my KSG. I eventually want to get a hard protective case but I needed something now to get it to the range.
If anyone is interested, I found this one on Amazon: Savior Equipment American Classic Tactical Double Short Barrel Rifle Gun Case Firearm Bag - Suitable for Subgun Bullpups Carbine Shotgun SMG SBR AR AK Pistol, Available Length in 24" 28" 32" https://www.amazon.com/dp/B07KX7SN4N/ref=cm_sw_r_cp_apa_i_tj7tCbQTS9HNB
I bought the 32" one & it fits great. I went a little larger because I have the extended butt plate and wanted extra room. It has large enough storage bags for shells and a divider for targets. What I like best about it is that it can hold and carry 2 rifles. My dream is to someday share the other side with a RDB.
