* Please be sure to check out our Sig Sauer Trigger Pull Reduction Kit, which will decrease your trigger pull weight while keeping 100% ignition reliability.  On average, you can expect an instant trigger pull reduction by approximately 1.5-2 lbs in Double Action and around 1 lb in Single Action in DA/SA pistols (and around 1 lb in SAO pistols) *
 
We are also pleased to offer the Sig Guy 2-piece punch kit that is extremely helpful for removing pins, as well as acting as a slave pin to ensure that small parts and springs are aligned during assembly and reassembly.  LINK
