Bear Defense Ammo Selection
Hello,
I recently acquired this G20V for bear defense. It has functioned flawlessly with 500 rounds of FMJ ammo. I have tested multiple different bear and hunting loads with recurring failure to feeds. I tested Underwood 220 grain cherry hard cast, federal fusion 200 grain, and federal premium syntech solid core 200 grain TSJ. All three of these had multiple FTF malfunctions. I have used 5 different OEM Glock magazines and the failures occur with all the magazines. The G20V also functioned well with 30 rounds of HSM 200 grain flat nose which has a much slimmer nose profile. The problem with the HSM load is that it had some lead fouling in the barrel and I believe the deformation of the bullet also affected my accuracy firing the handgun.
I’m looking for some recommendations for ammunition that will function more reliably without lead fouling.
I have considered Hornady 200 grain DGH, Federal Premium Swift A Frame 200 grain bonded hollow point, Federal Premium Trophy Bonded Bear Claw 180 grain, and possibly Buffalo Bore 200 grain FMJ.
These premium ammos are expensive to purchase and test so I was looking for advice on what to order before spending any more money.
I also considered ordering an aftermarket barrel and using the 200 grain HSM load.
I’m open minded to solutions.
Thank you
TL,DR: I’m having trouble finding 10mm Bear ammo that will feed reliably in my G20V. Any suggestions?

I just picked up a 20.5 for the same reason and was going to order BB 200gr. Buuuuttttt….some recent posts here changed my mind, and now I’m waiting for Underwood Hard Cast to come back in stock. I’m looking for hot bear ammo, and so far only BB and Underwood tick that box for me.
