I have been shooting 1911's off and on for 40 years, and to be honest I have never had many problems with them. I current own Four, a SA, Sig, STI, and since last Friday, a SS ultra Carry II. The first three have been almost flawless, but I had a problem with the Kimber on my first trip to the range today. I shot 150 rounds of WWB, and 25 rounds of Remington GS's. The problem was, if I loaded the mags [both standard Kimber] with 7 rounds the slide would not into battery on the first round, either by releasing the lock or by racking the slide. It would stop about 1/2 inch short and require a nudge to complete the cycle. Subsequent shots were fine. However if I loaded with five rounds, all was good. The pistol was well cleaned and lubed before shooting. The problem persisted through all 175 rounds. It appears to me that the mag springs are too strong, but what do you think?
Also I have on order two 7 round KimPro-Tac mags, but these were actually ordered for the STI Escort. Are these better than the standard mags, or did I just waste my money. Should I bite the bullet and get a couple of Wilson's?
BTW, the good news was that the GS's fed exactly like the FMJ's.
