Speaking of 1911's. Just picked up a Kimber Custom Target II the other day. Very nice shooting.
Took one of my Dad's guns with me too, to test his new mags and had a very odd occurence. I'll cut and paste the LONG explanation I posted on 1911forum below:
My dad has a 3.5" Officer's Stainless Double Eagle. It's been an accurate and reliable gun until recently. Since this is my Dad's main carry/HD gun this has been troublesome.
He had been experiencing FTF's with the bullets jamming nose-first into the feed ramp (mostly JHP's) as if the mag spring was too weak or the slide was cycling too fast. He'd never had issues feeding these rounds before, so this was very odd. As a problem solving step, he got some Wilson mags to see if that would help.
Since I was going to the range today, I took his weapon with me. I fired one mag out of my Cobra mag from my Kimber with no issues. Second round on the Wilson mag - FTF. I clear a few of these and keep going through to the second (and last) Wilson mag. On about round 3 it did it again and after messing with it for a second I got the round seated in the chamber with the slide still locked back and the magazine was out. I know you're not supposed to - but I dropped the slide on the chambered round. I've done this before on many guns and nothing has come of it. I know it's not the way you're supposed to do it, but the round was already in the chamber - so what the hell?
Well the gun slam-fired. When I went to lock the slide back (no magazine, no empty mag hold-open) it kinda jammed. I released the pressure and tried again and the firing pin safety and spring fell on the table.
It gets better: the firing pin stop was on the ground at my feet. The firing pin and spring? God only knows. Buried in leaves and snow somewhere.
Any idea what the hell happened?
