I have a S&W sd40ve that is super hard to break down or slide.It is hard for me much less my wife. It came with a 18# spring. I ordered a stainless steel spring.It came with a plastic spring. I had an option of a 13# spring. Will that work ok.
Welcome aboard. Best advice. Go to The M & P section.
Better yet, go to the "SD & Sigma Pistols" forum (where questions about the SD40VE belong).Welcome to the forum. As wingriderz said, go to the M&P section.
