Yes, please stop. 9mm FMJ is one of the worst defense rounds you can carry. You never "shoot to kill”. You shoot to stop a lethal threat. If they die, so be it. A FMJ 9mm may still kill them, but short of a solid CNS hit, it’s going to take a lot longer and that’s more time they have to work on killing you.
To the OP, with my screen name, you’d probably think the G-19 was my preferred choice for CCW. Until very recently, it was. Even in a Milt Sparks VM-II or EX, the G-19 was always uncomfortable and I had to choose my clothing carefully. I recently picked up a Colt Rail Gun for competition. As luck would have it, a well worn 1911 EX holster and Sparks 1911 IWB mag pouch came up for a paltry $50. I couldn’t pass that up, figuring it would be good for wearing to and from matches. Imagine my surprise when I found it more comfortable to wear than my G-19 in an EX, even with the spare mag IWB on the other side. Not only that, I can now use a wider selection of shirts without printing.
It works so well, I recently picked up a S&W 1911PD off this board for CCW. That way I can do extended range sessions with the Colt and slip on the clean PD when I’m done. After swapping a polymer mainspring housing, Wilson bulletproof slide stop & single side safety, and a short recoil plunger for the full length guide rod, the PD weighs 39oz loaded with nine 230gr Gold Dots vs. 33oz for the G-19 with sixteen 127gr +P+ Ranger SXT’s. A 6oz difference isn’t enough to make a difference and carried IWB, I think the 5” 1911 slide stabilizes the gun slightly better. Sure, I’d rather have sixteen 9mm +P+ rounds than nine .45’s, but the .45 is reassuring in cold weather when assailants may be wearing heavier clothing. In my case, I was often leaving the G-19 in the glove box and carrying a much more comfortable and concealable 3” Model 66 .357 mag. Far less ideal than the 1911 with 50% more capacity.
I still contend that using a 1911 for defense is best left to those who fully understand the platform and can perform most maintenance functions short of fitting a slid & frame themselves. Without that knowledge (or even with it), I’d highly recommend LAV’s 1911 operators course for anyone carrying a 1911.
