Parts work, some issues.

I'm not into spur type hammers, more into the "commander" type hammers; this will be the 3rd swap out on another Browning HP. The new hammer and spur fit well, still working on the safety lever to function properly. The prior two were no problem.

Hammer and sear

went in with minimal fitting, crisp pull, didn't use the springs stayed with stock

Well worth the money

My comment would be basically the same as Jim B's. These parts require the services of a knowledgeable gunsmith to install them, but it's well worth the cost. My gunsmith tried to do a trigger job with the original hammer and sear, but they wouldn't hold an edge. He replaced them with these parts, and not only is hammer bite largely a thing of the past, I've got the cleanest Hi Power trigger I've ever experienced, breaking right at 4.0 lbs like I asked.

Wonderful product~ but !

When this product says gunsmith installation "recommended", you should read gunsmith "required". If you are a novice, be forewarned that this set, or any others require some finite tuning. The sear on my set was not even close to fitting the hammer shelf well~ if this had been installed 'as is'~ this would have been a full auto Browning ! Major stoning was required to mate the hammer to the sear, and even after that was done, some refining was required to the safety geometry to get the safety to engage in both 'half-cocked' and 'full-cocked'. In the end~ it created a no slack/no creep and very crisp trigger pull with a significantly reduced locktime. Well done C&S !!!!
