| I do love a fine 1911, but I'm pretty much a traditionalist, and in the sense of one who primarily uses and keeps 1911s set up as self-defense type guns, so my approach is different than yours. Heavier springs around the original Colt mandate, which keep my guns reliable for me. | ||||||

For reference, the above message is a reply to a message where: I have a small box full of 1911 recoil springs from 9 lb up to 20 lb. I bought most of them for the aforementioned tuning of my two 6” STI 1911s. Some of the heavier springs were purchased years ago, when I was in a “full power” mode, trying to extract all that I could from the 45 acp round. That mode came to a pretty fast end, when I figured out early on that lighter and mid level loads usually provided much more accuracy. So I ended up going up just one pound on each after much experimentation. The 45 had a 10 lb spring and the 9mm had an 8 lb spring. While both functioned reliably with very light Target loads (as per their original intended design), the slide(s) were very lethargic, going back into battery. Again, they did so reliably, but too foreign a feel for me. You could actually perceive, in real time, the slide at the full reward point of travel and then beginning its ride home. And it wasn’t only those two STIs. Two guys at the club bought newer double stack STI pistols that run the same. It seems that the factory tunes them to run that way. Not what you’d expect for the potentially fast shooting these guns are used for. But, it works. My Tripp Navigator came with a 9 lb spring and has been fine in that regard. There was a small matter of fitment and oversized ejector related problems. But I was finally able to resolve that once and for all. Speaking of which, since getting it corrected, I now have well over 800, 100% trouble free rounds thru it too. |
