I agree with Shawn. I have owned my 40FS for about 4 years, and probably have around 8k rounds through it. I have shot a new M&P with the APEX kit and I would put the action in mine up against a brand new gun with the APEX kit any day. Mine has hardly any take up and is very smooth. Spend the money on ammo and shoot the snot out of it. When it gets dirty, clean, lube and repeat.
