Re: FEG PA 63 .32 acp
It should work considering its basically the same gun but sometimes higher tension springs are there for a reason and usually its safety reasons. Replacing the spring won't hurt any aspects of the gun itself but some guns (usually those of military configurations such as the FEG used in law enforcement) rely on spring tension for drop safety or accidental discharge safety. I'm not saying the FEG is one of those guns but I'm just throwing my .02 out there. Before I would go replacing any springs I would try to smooth some of the surfaces of the action. This will improve things quite a bit.
