Ok! So the springer compensator and threaded barrel from PistoGear.com. There were no instructions for either. The Barrel said semi drop in, I held it up to the factory barrel and they were practically dentical so I popped it in and it fits perfect. I hand racked a dozen rounds with not problems. The Compensator didn't have instructon but I e-mailed springer and was told to close the slide thread the compensator on until tight, then back it off to line it up with the slide. I used red loctite from an autoparts store as instructed by Springer. The compensator is tight and a pretty good fit I'm sure and extra few hundred at a gunsmith would have net me a flawless fit but I'm very pleased with the fit as is. Now to get it to the range and determine which reduced recoil spring will 14# or 16# will it require? Also time to upgrade the sigts. I'm thinking iron peep over red dot, this way I can carry without worrying about dead batteries.
