QUESTION BOUT DEFENSE ROUND FOR EVERYDAY AND SHTF DOOMSDAY END OF THE WORLD AMMO... I have a glock 17 that ive been using Winchester PDX1 9mm 124gr +P from walmart and saw some 147gr +p... Also saw many other companies with 115 gr to 147gr with bigger and smaller cavities... Which is better all around defense round? and also whats the highest gr that u can get in a 9mm? Is 147gr the most or they have higher? And whats the difference in power/Recoil... Also watched the show yesterday Doomsday Preppers... Kinda weird but interesting... If SHTF obviously you wouldn't use a defense round but a FMJ... So what would you stock up on Nato rounds that are 124gr that military use or 147 gr or if there is such thing as somthing higher... Also saw on youtube they have 9mm Armor piercing rounds? And we know its better to have a rifle but just curious as a sidearm... And curious also what rifle you would carry for doomsday since glock didnt make one yet... Whats the most powerful 9mm round in the market for JHP and FMJ... Wanna kill these ads? We can help!
