So I got my Bulgarian Makarov and I cleaned her up good tonight using the guide below. The firing pin is inserted correctly and the safety is in the notch and sitting on the upper lip of the slide. The guide says that considerable force may be needed to push the safety into place. Freaking thing won't budge. Any advice?
