That's not so Jim. You can remove that P-shaped clip through the back without dismantling, and then slide the safety barrel out as I said. I have done it quite a few times
They call the clip a safety spring, as it stops the gun firing unless you pull the trigger, as it might if you dropped it on the hammer
Had you followed my link to the strip down guide by jefL on UBC you would have seen my addendum explaining how to remove the safety spring without dismantling
But you've had some fun, and good luck with the comps
