One (or more) 'triangular' metal insert out of a spent primer does the trick.ColinC wrote:When I started shooting at ISSF Centrefire open competition I found my S&W 586 struggled to pass gun check on the trigger weights. A new rebound slide spring, trigger and hammer combination was only marginally better and on cold mornings it was also touch and go. (I am not sure of the physics of why pistols struggle to pass gun check on cold days, they just do, but that's another thread)
Anyhow I solved the problem by getting some long nosed pliers and squashing a .177 air pellet. I dropped this pellet in behind the rebound spring and it has passed ever since. Eventually the spring will work its way into the lead and I'll have to reshape it but three years later I am still going strong.
