This sounds like a complication that will keep me from buying an SP01. Is my P07 suffering from a similar setup?With the frame in hand the spring on the left side when out of the groove should look like it is up about 1/16" above the bottom edge of the trigger bar. The right side should be up about 1/8" above the bottom edge of the trigger bar. This should give sufficient upward tension on the trigger bar. I use a small pair of needle nose plyers to adjust the spring up or down. Pay attention that the spring is located center of the groove or that could possibly cause it to jump out especially if it does not have sufficient upward pressure.
