I have a 40P and love the thing. When I first bought it, it had FTF issues in about 5 out of every 100 rounds. I put a stainless steel guide rod in and have had zero issues in nearly 500 rounds since. The old, plastic guide rod can weaken with age letting it bend and I think that puts more drag on the slide return action. The steel rod keeps everything lined up.
Also, these have an odd sight cut that is difficult to find replacement sights for. Not impossible, but difficult. Other than that, they are fantastic guns.
