The 10mm is an expert's pistol. Still, their are a considerable number of people who could use it well.
The best policy, in my opinion, is to allow individual troops to procure their own weapon, from a choice of allowed calibers. The US military still uses 9mm,.45, and .38 special, for example. Perhaps we could allow others for Special Forces. Britain had this policy for much of its strongest days, and it worked well. Some countries, such as Columbia, I believe, still follow it.
A pistol is a very personal thing, and having your very own, chosen by you, can give an edge in proficiency and confidence.
Hmmm, I've owned and shot various .40 and 9mm Glocks. Last night I shot a Glock 29, the sub-compact 10mm.
It was the first time I'd shot a 10mm of any stripe. I'm not overly fond of the baby Glocks, but I had no problems with this one. I cleared a rack of 6 plates at 15 yards, first time with no problems. (180gr full house loads)
I like the 1911 also, don't currently own one, but do have a S&W 625 in .45acp that is one of my favorite shooters.
Excactly. If I am behind enemy lines....give me a .22LR with a silencer. A sidearm is a personal thing, and depends entirely upon the mission.
