I've had nothing but trouble with Kimber. Feedway stoppages (even with Wilson mags). Slide stop walking out. Barrel bushing taking a trip down range. Sold it and bought a Glock. Zero issues there.
Also had problems with STI. $60 mags that, out of the box, like to squirt rounds out. Doublefeed city. Also, unable to load mags to stated capacity. With vetted mags, the gun was awesome, but it was just too massive for CCW.
Never had an issue with a Springfield. Nor with any of my Glocks. Regardless of caliber or whether I had a light mounted or not.
