Providing one 7rd and one 8rd magazine seems to be the factory standard when it comes to 1911's. I have no experience with Ruger 1911 magazines. I own many Ruger's just not the SR1911. I have lots of experience with Kimber 1911's. While I love 1911's they make I hate their magazines. I consider them range only. I hope Ruger brings their A-game when it comes to the magazines. Most of FTFs were from cheap magazines. If you encounter some while breaking in your SR1911 try a magazine from Wilson Combat, Chip McCormick, Ed Brown or Les Baer. Especially, if you are going to use it as a carry piece. Yes they are far more expensive than the no name 1911 magazines you can find at gun shows, but none of those I would trust with my life. I have far more "Range only" magazines than carry magazines. For ammo I would recommend using 230gr Hardball (FMJ) as your base line. It was what John Browning designed the 1911 to use. Brand doesn't seem to make to much of a difference when it to strait Hardball, but most of mine is Winchester or Speer Lawman. Avoid the Remington/UMC 185gr SWC I might have gotten a bad batch as dealer was offering it a price that was way to good to be true. Not sure if it was reduced charge or bad power. Ammo buyer beware 75% off ammo there's probably a good reason why. Even my Glock 21 had the same issue of off the paper low with my normal point of aim shots. It might have been that one batch, but I haven't touched it since. When choosing Self Defense ammo look for reliable feed that doesn't damage the round or stop course fail to feed. Having the same grouping as the hardball would allow you to use cheaper hardball for break-in and some of your range practice. 500rd break-in isn’t going to be cheap, but using hardball can reduce the expense. I have been very happy with Speer Gold Dot 230gr JHP for 15+ years. I’ve been testing Hornady TAP 230gr JHP. Looks good so far, but not ready to change my carry ammo yet. MidwayUSA stopped carrying Extreme Shock ammo before I finished my testing in 38 special, 45ACP, and 5.56mm. I’ve stayed with 230gr bullets as that’s what my guns like. I know I can change out springs for light loads or hotter +P loads. I haven’t made that jump yet, but I’m very close. That adds another layer of complexity but it’s been years in the making. Just find what your gun likes in its stock configuration. So just buy one box of each type of regularly/easily available ammo in your local area. Once you know what works best for you then look to buy in bulk for your practice. Good luck and stay safe.
