Have several WC 1911 45acp mags never had any problems. Four or five years ago tried Tripp Cobra 1911 mags they are as good or better than Wilson Combat. Just my 2 cents.
If I'm not mistaken some of Trijicon pistol dot optics are significantly more expensive. Nothing against the NRA, I'm a Life member, but I have experience with Sig's dot optics really like them. I replaced two Trijicon optics with Holosun EPS's.
