Rather than let this J&J Slide thing die I have a couple more questions. 1) What determines whether a short or long one is needed? Now that we've got that out of the way 2) I would assume it is tuned by the ring on the slide? Is there a method to tune this device? I'm speaking of a systematic method of adjusting it to your gun like the Hopewell method to adjust a tuner?
3) Does is come in UK Blue?
