Hi. I am new to this forum. I have a Model 59 that throws the slide stop out of the gun during rapid fire. My ginsmith advised me to replace the recoil spring. I found this strange but i did so. It helped for a while but the issue has re-surfaced. The s/n is A2466XX. Can anyone possible provide any answers? Thank you! Tylerboy. ([email protected])

PS-Can anyone advise the date or year of manufacture?
