What model 9mm 1911? Commander? Full size? Lots of variables. Need more info to help
Full size, Remington R1 Enhanced.
Wilson 47d mags will run flawless. NOTHING from RIA is worth spending money on imho. Buy quality once instead of 4 times
Except those appear to be for 45acp.
As of yesterday, Wilson was showing all 9mm mags as "out of stock" I use Tripp Research without problems.
The recently deceased ToddG of Pistol-Training ran a 9mm for 50,000+ rounds and filed many reports on his experiences with the gun and the mags. pistol-training.com » Blog Archive » Springfield/Warren 9mm 1911 50k Report You'd do well to pay attention to what he wrote.
