My next purchase is between the M9 or M9A1. No, I'm not waiting for an A3.
Basically this purchase is for 2 reasons: nostalgia because I carried an M9 in the military, and because I don't have a 9mm.
Even though I carried the M9, I'm leaning towards the M9A1 after holding one recently and noticing the difference in the grip. Plus, the option to add a light is nice.
Drawback to me getting the M9A1 is that I have holsters for the M9 already which don't fit the A1 (specifically, I have a couple blackhawk serpa holsters). Plus... It's not a basic M9, so for nostalgia purposes I can't say it's what I carried. Sounds stupid but I can't really explain it.
Hard decision... They're both the same price so that's not an issue.
ETA 4/30/15: Obtained the purchase permit yesterday (finally! ). I placed an order with ImpactGuns for a new M9 with 15 rounders
Ultimately nostalgia won this debate for me.
