I haven’t noticed mine getting sluggish from not cleaning either. I have just over 500 rounds out of the gun. Only issue I had that concerned me which has since been rectified, was the slide not staying locked back (a few times )on the last round. It was my thumb riding on the slide stop. Now, the firing pin breakage concerns me. on Sig talk I have read of Four guys with the nipples breaking on the firing pin. Some guys think it is due to dry firing and some guys think it has to do with the firing pin dragging on the case.It is not all that uncommon to see, But seems a little Deeper and longer on my 365.
