I am in the market for a 24/7 in either a PLS or an OSS. I am unsure of which caliber to get. I will be carrying this gun some, keeping it handy at home for home protection, general target shooting and plinking, and I would like to go to a competition shoot every once in a while. The 9mm is attractive to me for its low cost and I am already reloading 9mm for another gun (my wife’s). I like the 45 for the mass of the bullet. I'm on the fence about the 40 because of some of the things I have read. I am looking for a good conversation about the pros and cons of these three caliber choices. Thanks
