Some Noise in new SP50 Phoenix

[gaurav31dec]

Hello Friends

I just received by new Precihole Phoenix SP50. I tested about 40 shots with H&N Sport.
Every thing looks butter smooth and the accuracy is great although the recoil is bit more than what I expected.
But there is a strange khat khat (metal sound) coming from the action area when the pistol is shaken or moved in idle condition. The same is not there if I do the same when the pistol is cocked and ready to fire.

Please guide if this is normal or I need to check with Precihole support team.

Thanks
Gaurav
