My first 1911 was a Seriea 80 which has a firing pin plunger, but in my opinion that was a good thing to add to the design and IMHO does not take away from the novelty of the firearm.   I have heard from so many of my friends that Kimber makes the best 1911s, but I still have yet to understand why I should bother spending over $1000 on  a firearm when I already own two 1911 handguns that cost me less than $400 each.   Springfield Armory GI models are very well made and I have had zero reliablilty issues with my guns.   I have to admit that I am not one to push the limits on the types of ammo that my guns eat and I think that may be the real reason I don’t have issues with them.

When I first carried for work, I carried a Colt 1991A1 and used hollow points, but I  had an awful lot of malfunctions with the 2nd round.   Not that often, but maybe about 1 out of 75 rounds might not seat all the way and I would have a stoppage.   I was told to polish the feed ramp and I did, and the gun did run more reliabile, but then I did have maybe 1 out of 300rds jam  on me.   I took a good look at ballistics charts and realized that a 45acp FMJ does enough damage and worrying about bullet expansion with such a large caliber was kinda pointless.   I wouldn’t get too caught up in doing too many tricks to get your 1911 to run reliable.   Find the ammo that really does work, in my case, FMJ and try sticking with Wilson combat magazines or Chip McCormick.  I mostly use 8rd mags and although there are some that claim that these are not as reliable as 7rd magazines, I have had zero issues.   One thing I do not do any longer is one up the magazines.  There seems to be some magazines seating issues if I force an 8rd magazine in the guns with 1 round in the chamber.
