I came across a Power Custom brass 2 piece GF new in bag. I'm currently attempting to install it on my OM 41 mag. Easy enough, open trigger slot for SBH trigger, file work to fit to main frame and hammer ears. My question is about the hammer strut/spring seat on the GF. This 1 piece saddle mounted to the front of the GF appears to make the strut/spring a semi permanent mount, no easy way to remove it once it's pinned to release pressure from the trigger. Is this the way it's supposed to work? And does the spring itself just sit on top of that saddle?
