Well, as far as the M9 goes, I have nevr had a problem the design. However when I was a young Marine in the first Gulf war, I watched my Ssgt. dump 6 rounds center mass on a towlie and it enver slowed him down. It took a burst from the '60 to finally stop him. Lesson learned, 9mm FMJ ammo is crap and lacking anything resembling stopping power. Training was good, shot placement was right on, it was just a failure of the stopping power of 9mm FMJ, plain and simple. If you are going to use FMJ ammo, I agree with the idea of going back to the .4 ACP.
These days I'm a combat arms instructor in the USAFR. It scares the crap out of me the way I see some of these idiots handle the M9 and I would NOT want a single action 1911 or a Glock put in their hands!!!
Before the lectures begin about better training is needed and so on, you're preaching to the choir here. The Air Force only shoots one day with the M9 and for catagory A shooters (cops, PJs, TACP), it's once a year, catagory B shooters (such as CES, some pilots, etc) is every 15 months and catagory C shooters (medical personnel for example) shoot only once every 3 years. IMHO, it's substandard training but we need money to buy ammo, people that want to shoot and take it seriously, and time to get them on the range and work with them for longer than just one afternoon.
What I would like to see is a .45 ACP adopted with the DAO style trigger. Soemthing like a the HK USP-45 with the LEM trigger, a Sig P220 with their DAK trigger or the S&W SW99 with their OA trigger (I think that's their version of a light, long DAO trigger) be adopted. IMHO, this offers the best compromise of a trigger that is light enough for shooters not familiar with a true heavy DAO trigger to shoot better scores, long enough for new shooters to realize they are pulling the trigger before they fire a round and firing a caliber that is a better fight stopper than the 9mm FMJ. I would not like to see a 1911 adopted for general issue due to the short, light trigger in the hands of shooters that have trouble remembering to take their finger off the trigger or reapplying a safety lever. I would also not like to see the Glock adopted due to the lack of a safety lever and is capabile of firing by shooters leaving their finger on the trigger when they go to reholster the weapon. Sure you could add a manual safety lever but now you have the same problem as giving them a 1911. Of course, the ideal situation would be to train them up to high speed, low drag standards but with the limited budget, time constraints and the Air Force attitudes about small arms training, I'm not going to hold my breath of that ever happening.
As for the idea of letting everybody pick whatever they want, that ain't gonna happen. If it did, I would be against it 100%. If you've never worked an armoury before, believe me, it would complicate matters beyond belief! We have to inventory EVERYTHING in that armoury every day and with just M-16s, M-4s, shotguns, SAWs, M-60s, M-240s, M9s, M-203s, training ammunition, dummy ammunition, and anything else that is stored there. Oh, and make sure the count is ABSOLUTELY correct or you may face the possibility of brig time if anything comes up missing!!! And then don't forget the different ammunition, various holsters, various magazine pouches, various magazines, replacement parts for each type of handgun and training for CATM personel to work on them as well. :banghead: Do you see where this is going? That would be a total logistical nightmare and if you order ammunition for one day of shooting, I can guarantee that it's going to get f'd up as a football bat with the wrong amount of ammo of caliber X either being logn or short and caliber Y getting what caliber X should have got. No, it ain't (at least it damned sure better not!) happen.
