Wc ring hammer - Wilson Combat Bullet Proof Retro Commander Hammer

I purchased this item for my SS 5” government model and unfortunately it was Not working like DROP IN parts!!!!!! It was required professional gunsmith to recut sear hooks or I was pushed to buy EGW shortened .005 Springfield hard sear and EGW ball head disconnect to make it work! Try it install to my Springfield 4.25 and this hammer is working! So you may be lucky but Wilson Combat saying in description it is for professional gunsmith fit!!
