Every time I try to fold the mainspring housing into the grip it pulls the pin out and thus wont fit into the grip and then the pin needs to be reinserted then the problem repeats itself. I’m cleaning this firearm for my grandpa it’s not my own and I’m not fully familiar with the parts or mechanisms but I’ve watched at least 4-5 videos ag this point and have been working at it for 4 and a half hours to get to this point at which I’m fully stuck and need any type of feedback someone can give me. Please try to keep in mind with your responses I’m fairly new to this firearm and firearms in general and may not know what a word means. Thank you so much.
