I took a supersport(same mech) trigger apart & carefully polished the burrs off ,then shimmed the side play on the pins with small nylon washers I happened to have . Improved it a lot, still have the test target I shot at 10m with it, 10 shot cloverleaf. The adjuster screw should be screwed out to lighten it too. still not a patch on a record though, but at least it had a predictable let off point. Hold senstivity is crucial on these rifles, too hard a hold will definetly adversly affect accurcy.
