Quote:I do reload my own ammo so that's not an issue because I know that 10 MM can be hard to find. I heard you can reload the 10 MM really hot too. The S&W .40 is what all law enforcement carry so something has got to be good there. I was just looking for some opinion.I think it depends on the type of shooting that you anticipate doing the most..
For most Urban Self Defense purposes, the .40 is very adequate.. It's certainly ahead of the 9mm and .38 spl that most LE agencies carry when it comes to the more critical shooting situations
For Hunting and competition shooting where a Power Factor is involved, the 10mm is a more desirable choice, or if it is a situation where you are likely to be defending yourself in a more open environment..
I've been a big fan of the 10mm for years and at one time owned five of them, and still do have three..
Early Thompson Auto Ordnance
Kimber Target model
Para Ordnance conversion from .40-10mm (16rd capacity)
Since I also reload, the cost factor over other calibers is negligible...I would, however, suggest buying a bunch (1,000+ rounds) of Starline brass soon, if you are seriously contemplating getting into the caliber...I'm still using a lot of the Hornady and other brand brass that I've accumulated over the years, (I have a friend that used to manage an indoor shooting range and he would save me the once fired brass) but have 1,000 rounds in storage that I bought at $101 and now is going for $136+ (Starline) and $176 (Sinclair/Brownells)....
I developed a love for the caliber after attending the Chapman Shooting Academy many years ago as a Police Firearms Instructor and many of the attendees were shooting .45acp pistols and training on moving targets that were moving at 10 feet per second and finding out the lead that was required with the .45 at the various distances..There is a big difference between the lead distance between a .45acp at 850-900 fps and a 10mm at 1200-1350fps...when fired at a moving target from 25, 35, and 45 yards..
For competition shooting where a power factor is involved, the 10mm can be loaded to stay up with, or exceed the .45acp as well, with FMJ rounds...
It's very true that the 10mm was the original caliber choice for FBI Agents, until it was determined that many could not handle the 10mm...simply due to the fact that even the agents were not, as a group sufficient shooters by nature, capable of more than basic general qualification standards...Very few are 'competition' grade shooters..(or pistol shooting nuts
).. The recoil is relative to the .40 as the .357 magnum is to the .38 special... And rather that upping the requirements for training and results, the FBI chose to look to an easier round as a substitution..
