I recently purchased a Sig SP2022 and the take down is super difficult. The problem is that the slide lock which need to be pushed from the right side have a groove on the pin where a retaining spring (in the frame) locks it in place. I have pretty strong fingers but I cannot push it out w/o using a rubber coated long nose pliers handle. My finger tips are all sore now for trying w/o the pliers and using a tool is really awkward since you have to control the slide position held back at the same time.
I am planning on the following options;
1. file the right most part of the pin so the spring is not seated as deeply (just the side where the spring is around 4 o'clock and 5 o'clock, forming a rounded D ).
2. ramp same area above a bit so I can slide it out a little easier. (this is my choice right now)
3. modify/replace the retaining spring so it is not as strong.
Is there something wrong with my thinking? Which makes the most sense (if any)?
Any advise (or scolding
