I am a patient man so I am always on the lookout for spare partsYep you will need to bush all your bolts or have a separate firing pin assembly... if you used a sfp in a lfp bolt body you would probably get massive primer flow and eventually it would probably tear up the tip of the fp especially if your loads are hot.
Tbh I like how LRI does the bushing but their are pros and cons to how each Smith does it... I eventually just got all factory sfp bolt bodies and fp but I get it that lefty situation is tough.
