Howdy! I would like to share my experance with the wire springs in my USFA's. I bought 2 USFA premium single action's custom ordered to my specks. After getting them & shooting them as they were for a short time, I ordered a set of gunfighter springs (wire trigger/bolt springs) with a lighter hour-glass type main springs. After installing them, I noticed a differance that the guns were a bit smoother, easier to cock, lighter trigger pull and timing was still good, I was pleased. A few broken hand springs later, I changed the guns to use the coil type springs instead. Now I was happy because I was sure I now had trouble free pistols. Fast forward a year later, I had just read the articial in the Nov. Cowboy Chronical & like a day or two later I was doing some dry-firing practice & notcied the cylinder not turning correctly on one of my pistols. Well checking it out found that the bolt on that gun was not coming back up to stop the cylinder rotation (kind of stoped up aganist the inside of the frame). So I disassembled the revolver but the spring was not broke, so maybe it had become week, then I tweaked it (bent it) a little to but more pressure on the bolt. Reassembled the gun but no change, still did it, so I put the original flat springs in both guns and guess what? they worked just fine. The down side is flat springs tend to break also the trigger pull went up (not what I'm used to) so I tried thining down the trigger side of the flat spring(s) to reduce this and it worked. Only time will tell if this set up will hold up but I will suggest if your are using wire springs CHECK THEM! It might be a good idea to replace them once a year. I will stay with my modified flat springs untill someone can come out with a better wire replacement type spring. One that will put as much pressure on the bolt as a flat spring but has the same lighter pressure typical of wire springs for the trigger pull. Just thought I'd share my experance with wire springs.
