Good luck changing sights on any HS Produkt pistols. Some of the tightest fit sights there is. May have to send to someone that has the capability and right equipment.
Yeah I tried that and snapped the front sight off. Have done that successfully with several other brands but HS Produkt and S&W are notorious for their tight fit. Springfield Armory uses a hydraulic press to adjust or replace those sights.Some leather strips, ball peen hammer and a steel or brass punch the appropriate size. Nothing to it, simple as baking pancakes
Damn what a link
