That’s about how long I’ve been using Wilson Combat Magazines with my 1911’s, and after 20yrs I’m sticking with them. I have never felt the need to use 7rd magazines, nor have I felt that the 10rd extended magazines were of any use to me. I’ve been running and gunning the 8rd Wilson Combat magazines with very few issues. The truth of the matter is I’ve run some of these magazines long enough for springs needing to be replaced and all of the springs replaced in my 1911s. Everything in the firearms industry wears out and breaks at some point, it’s just how long it runs and what it’s failure points are.
There is always somebody new to the world of 1911s and you don’t always have to buy a high end 1911 to have a reliable one. I’ve shot 185gr 45acp FMJ and 185gr hollow points, 230gr RN and 230gr HP rounds in my 1911s. I’ve done barrel throating and polishing of feed ramps and got good results and I’ve seen the difference my guns jamming with hollow point ammunition when using USGI mags, and the same ammo NOT jamming with my Wilson Combat Magazines. Most people using the extended 10rd magazines are using them for competition shooting sports.
