The PM9 also has a dovetail front sight, as opposed to a pinned one on the CM9. I ordered mine with the factory Meprolight Tru Dot night sights.
I waited endlessly for a Shield, so ended up getting a PM9. Bud's gun shop has the best available prices on all variations, and most are in stock. Most get the CM9 (identical dimensions to PM9) because they're essentially the same gun except for the frills. Identical as far as function and reliability, that is. I really wanted a better front sight so I went with the PM9. Neall
