The purpose of a reduced weight hammer, (just like a reduced weight firing pin), is to reduce the lock time, which makes it easier to get a reliable low weight trigger pull. Reduced mass hammer will produce *higher velocity* which gives a better energy transfer from the mainspring to the firing pin. (i.e., you can technically use a lighter mainspring - which gives a lighter trigger pull) and still get reliable primer ignition. Of course there is a fine balance between reduced weight and structural integrity (or having the mass reduced too much for reliable strikes). Our hammers are ABSOLUTELY designed with this in mind and are designed to achieve this balance. Our skeletonized reduced mass hammer uses the lineage, reliability and mechanics of the legendary SIG X5/6 SuperMatch hammer as its baseline of performance. This hammer has several advantages- it will be manufactured via precision EDM machining out of 'tool steel' that will be hardened....and yes, there will be special attention paid to the hammer hooks, so the trigger pull will be smoother.We are NOT making this hammer "just for the LOOKS", that's for sure.....we have performance very much in mind as well. It will certainly beat having the MIM hammer that we have seen in quite a few P-series guns.


Will fit all SAO P220, P226, P229 models (including all Legion SAO models). Per our testing - on some rare occasions - it may require additional fitting in some German "S" (a.k.a Gen I X5/6) models, as well as Gen II X5/6 SAO models.All triggers, hammers or any other gun parts are intended for installation by a gunsmith or a qualified armorer.
