I have the Alien Gear IWB for the Witness PS 9 and while not perfect the 10 mm Witness fits just fine. To my eyes the frame of the PS 9 looks wider side by side with the Witness steel 10 mm.

I use my left hand to hold and my right to "rack" the slide, It is much easier that way. I'll try the finger over the rear sight tomorrow. Good luck.

I recently bought the wonder finish 10 and I love it so far. I changed out the recoil spring to a 20 lb Wolff and the Hennings cone fit guide rod. The trigger on mine is smooth as silk. I also have a Witness PS 9 mm and the trigger on the 10 is both lighter and smoother in both double and single action. If anything the single action is scary light on mine. Order a crossman LPA MIM rear sight (model number 2300-010.) The PS 9 shot low as did the WF 10 , I put the MIM on the 9 and it fixed that, I'm going to put one on the 10 as well.

Thanks. I went to their site and they had no tanfoglio items available.

I don't think the magazine spring is any issue, no ftf or anything else other than I can't fit as many Underwood's as Armscors in the same magazine. I wouldn't think there would be any size differences between the two rounds so just wanted to know if anyone else has the same experience.

I recently bought a witness standard steel in wonder finish. I swapped out the guide rod for the Hennings cone fit and a wolf 20 lbs recoil spring. I took it to the range today and fired 150 rounds of Armscor and 20 of Underwood 165 grain. No issues other than shoots way low just like my witness PS 9 did before swapping the rear sight out. One odd thing was that I could easily put 14 rounds of the armscor in the magazine but only could put 13 of the Underwood in. Anyone else have the same experience?
