    .357 Sig vs 10 mm

    I have enjoyed reading the lasest posts on the .357 Sig. I, too, think it is an great round and have carried and shot alot through a Glock 23 with a Lone Wolf barrel and a Sig 229. My problem is that recently I gave started to carry a Glock 29 and love it. Some range time is also being spent with my Glock 20. I find both guns fairly easy to control. If you find yourself fainting away from your favorite 45 ACP, looking for the next better round, I gave found that the 10 mm fills those wants and needs!

    A while back I planned on getting a G22, intending to acquire 9mm and .357 SIG barrels for it. Unemployment put a hold on those plans, but I hope it eventually happens. Never fired a 10mm. Will have to give it a try. I, ofr one, enjoy shooting different calibers and different makes. Never cared too much for having several guns all of the same caliber to "save ammo room."

Fair enough, but what some might consider a compromise (either in capacity or punch) I see as the right fit, for me, and the number of firearms I want to own.
    Disagree with you here, the .40s&w, .357sig, and 10mm all use the same diameter brass, they'll stack the same amount of rounds in the same amount of space..

    My 10mm EAA Witness Elite Match with full house FMJ loads is my woods gun of choice..

    Well, I knew that (use the same diameter brass, aka the .40 S&W is a cut down 10mm), but for some reason assumed 10mm had less capacity. I'm wrong. Mud on the face.

    If. I say if I did get out of my standards and into something more interesting....and the availability was there....and the affordability was there....and discounting my interest with the 45G.A.P. cartridge in the Glocks, I think I would choose the 10mm over the 357SIG. Thing is, my previous G21 and G30 didn't work out so well for me when I had them, especially for carry. With the SF frames, who knows. I just haven't tried them personally, but the ballistics speak well of the 10mm, and I speak highly of Glocks. One thing sticks in my mind about what our instructor said in the Glock armorer's course, and that's a little to do with history and the now. He said what used to be the best defensive ballistics in theory were that a bullet or cartridge was designed to have the most penetration and energy while staying inside the body of the intended target. These days, and the current thought is to have a cartridge that will go into the body with enough velocity and energy to do the most amount of damage and go in and out leaving the largest hole upon exit. To me, that well defines the 10mm cartridge whether it's coming out of a Glock, or something else. I believe in the current theory by the way. Glock on!

    The 10mm is not ''the next better round'', it is THE round. While it may be debated based on preference to size of carry gun, ammo availibilty ect...the 10mm reigns supremely above all others in the power range and versatility. This cannot be denied. If someone were choosing an auto to accomplish a variety of requirements, the 10mm is the only choice.

    I have the G20 and a 229 in 357. The 10mm has allot more punch. It could be an overpenetration problem. I really like both guns but ammo is high. The 40 barrel will save you some ammo cost.

    Bob boatman has a good book out about glocks and his love of the 10mm. Some good info in it.

    Just my opinion but I think the 10mm is a little much for the 1911 platform.

    My Colt, from the 1991 is still going strong, at about 80,000 + rounds. I did replace the barrel, started to loose it's accuracy.Did a lot of action shooting in the 90's. Lot of old boys ran 1911,in 10mm and held great. It's a great round. I do like the 10mm in the 170 to 200 grain area better.For up close defence from people, I would give the edge to 45 ACP 230 grain, for all around 10mm is great.

    10mm vs .357 Sig, really about the recoil and recovering for 2nd shot, right (if $ is not an issue)? It is more about the shooter's abilities and comfort.

    I am slowly circling the 10mm cartridge for my next gun.

    In Iowa, it is illegal to handgun hunt with a bottlenecked cartridge, so .357 SIG is out.

    Plus, those gorgeous straight walls on that 10mm cartridge fairly scream "Reload ME!!!!" So ammo costs are simply irrelevant for my purposes.

    Technically, the .357 SIG should be more reliable, due to the bottleneck cartridge, but I have not data on the reality of that.

    120mm, do it, but if you really want a screaming bottleneck, check out the 9x25! It is a 10mm case that takes a 9mm pushing it to 2000fps!and it comes in a drop inbarrel for the g20.

    The 10mm is a very versatile round. I wouldn't mind getting my hands on a 10mm 1911 one of these days.
