JJones, thank you for the barrel blaster info, I'm going to look into it. On another note the ejector which came with the Sarco kit isn't working correctly with my snap cap test on my current mule build. However in all fairness I can't pull the slide back with near the force a real projectile will. The barrel and barrel bushing dropped into my Sarco Para slide. The build loads fine but doesn't eject properly when cycled manually, if you can hold off on install until I have time to test fire this pistol to see if the added force will cause proper ejection. Just trying to save you from mounting a bad ejector.
