So, I was nosing around my favorite sports shop today looking for some 9mm 124gr. Gold Dot but, like always, it's not to be found anywhere around here, for love or money, as it grows wings and flies off the shelf. They had some Sig Sauer V-Crown 9mm JHP 147 gr. on sale and having never shot anything over 124 gr. I picked up a couple of boxes. I have not looked up the ballistics but am wondering why the 124 gr. wasn't on sale while the 147 gr. was...Hmm? Anyway...My intent is to use this in my Glock 19 and my Glock 43. Question: On the smaller frame guns like M&Ps Shields and Glock 43s is there any negative side to shooting the heavier grain rounds besides the fact of more recoil? Question: What Personal Defense Ammo are you using in your EDC firearms and why? I'm just curious... The reason might be availability (like me as I want Gold Dot but impossible to find), cost, ballistics, or the fact that as long as it's a Hollow Point who cares. I used Independence 115 gr. HP for a long time because it is reliable, fairly priced, and I'm accurate with it. Anyway, I will shoot a box of this 147 gr. this weekend but I am betting that I will purchase the 124 gr. for the smaller G43 but, we'll see... Currently, I am a solid shooter at 30-35 feet and training at 45 foot (which is a different ballgame, so not so solid) so I will be able to see fairly quickly how this heavy ammo affects my shot groups.
