Bang it through and don't worry about it They were built like tanks. I put bbb steel through my zabala and that's still full n full. The previous owner did the same too and the gun shows no scars whatsoever
I went with the intention of either getting the franchi or sx4 and came away with the sx3 as it felt and looked a more well built bit of kit. That was 2 years ago and the sx3 has been faultless I can't complain about it.
Make that 5 as I know a lad who had one and every time he closed the gun it went off💥 accident waiting to happen took it back got a replacement and this one closed fine but every time he fired it double discharged so took it back and got full refund
