I shot USPSA and built full house 1911's for over ten years in the late 80's and 90's. I recently attended the 100 aniversery celebration/operators class at Ft. Harmar. Bill Wilson was there and John Miller. Small guns were discussed some, but getting any sub 5" 1911 totally reliable is difficult. It can be done though. I'm currently studying what Bill Wilson told me about how to make them work. Sorry, but Kimbers are not reliable guns. Just sell them. I'm currently building a SA micro-compact as surprisingly i know of at least one which appears to be very reliable. But SA's are not built all that well, so the price of the Micro is steep as you will probably end up replacing half of the gun. Buy one used if you want to try that one. The ACP colts with cone barrels tuned to delay the unlocking process is another tach i'm taking.
Single column nines just don't get it for me. While the EMP does have a nice trigger, the new mini nines don't, have marginal bullet performance AND no capacity. They just don't make sense compared to say a Glock 26. Of coure Glocks are about the least fun gun to shoot on the planet. Whippy, not accurate, and of course that safe/sucky trigger.
The 1911 when totally reworked such as a Wilson gun or a full custom gun like i used to build is probably the most fun gun an experienced shooter will ever enjoy. The trigger quality and accuracy are unequaled by ANY pistol ever produced. But the 1911 is for advanced shooter only that have put in at least three years of intense competition. If thats you, my advice is to sell sell all your junk 1911's and buy or build a top notch high level 1911. Steel guns are really nice. They don't jump around on you with that heavy slide on top of that nothing frame.
My take at the moment- HK USP 40's for home defense, Glock 19 or 26 for carry, a dead reliable 1911 for fun and games.
