I know this is way overdue but I finally got a chance to take out the new M9A1 and all I can say is WOW!
I didn't really have any complaints: I love the size of it (I'm a big guy some of the other 9mm I looked at, the SR9 in partcular just seemed kinda small really) and the sights from the factory were very accurate. I put 200 rounds through it and had zero FTF or FTE. Another bonus that I didn't realize at first was that the 2 mags that came with it have some sort of special coating on them and the mags alone retail for about $55 apiece.
Lastly,I prefer having a hammer instead of a striker fired pistol; though this came down to nothing more than nostalgia of some kind...
My only two very minor complaints with it are:
1. It came with a plastic guide rod... ***?
but this is easily fixed with an order to Beretta
2. I put a TLR-1 on it and it is now (very slightly) barrel heavy. This is remedied with practice I suppose.
Anyway I think I got a great firearm at a great price and I woudn't hesitate to buy another. Thanks to all those that contributed!
