Add up to 2OZ +filament to your tx22 competion slide. Im still printing this test model and waiting on the weights. I printed @Xennial-Bellwether:b tall sights for the tx22 and used that dovetail as the starting point for my weight, Us their front sight if you're actually using irons. Non sighted verions will follow success of this model. As well as smaller versions for those who need less weight added. Make at your own risk.
