Warning: Learning to shoot even a cheap 1911 trigger will ruin you for all others: everything else will feel long, heavy, gritty, and unpredictable.
If you can master the DA trigger pull, you can shoot just about anything well.
One distinction to make that would be helpful. By 45ACP, some people mean a 1911 platform, while others just mean any semi-auto chambered in 45ACP.Thoughts on my Son's 1st .45 ACP
