.357 SIG vs 9mm Parabellum +P+ vs 10mm Automatic in the Land of Trucks and SUVs

[MasAyoob]

Hey, Anthony:

You're not paranoid to want the manual safety conversion on the Glock. A lot of us grew up with cocked and locked autos and the manual safety is a paradigm we're comfortable with.

Rick Devoid is doing the Cominolli safety installation (right hand only), check him out at www.tarnhelm.com.  I have the conversion on one of my Glock 17s and it works fine.

best,
mas

Anthony, I've got a few different thoughts. The first would be to belly band the 10mm, or a magnum revolver and carry a second full size gun, perhaps a magnum revolver, also. Use either as a primary according to the situation. Stoke the 10mm with something that will do the number on cars (think hard nonhollowpoint bullets), keep the other gun set up for frontal shots against lightly dressed humans. The "biped buster" should be the more quickly accessable. FWIW, I would never carry a stock Glock without a proper holster. You'll also need a third gun available to the weak hand (unless you carry one of the cannons weak side). It could be anything, even a P3AT, but, of course, bigger is better. You'll have to decide how much artillery you're willing to carry. Because of the flat nature and higher capacity of the 10mm plus the need to hit a target that is likely moving, I think the 10mm would probably work better than a six shooter. The wheel gun would offer better ammo versatility I would think.

I'm leary of some of the Double Tap Gold Dot loads that are noticably faster than Speer's. People were discussing that stuff on Marshall's forum and IIRC, Marshall was concerned that the bullet might be getting pushed past it's velocity window and that stopping power would suffer. A search on that forum might kick something up. Posts I've read online left me feeling that hunters were underwelmed by the DT 10mm GD performance.

If you want to really tear through cars with a given load, stopping power will likely suffer, but you have to hit them to hurt them. I think non, or very slow expanding bullets would be your best bet. In revolvers a superhardcast wadcutter. Aside from that, if you're looking for a compromise load in 10mm (in .44 mag. the 180 gr. XTP would be a great general purpose load, you could switch to Federal 180s for an anti-personnel load and likely have no shift in POI)) it goes without saying that a bonded bullet such as the Gold Dot or HST (if it's available in 10mm) are the ticket. You're on the right track if you're looking for a jack of all trades by investigating the bonded 10mm loads that are out there.

The Hornady XTP has shown (in my tests & my dead critters... it's one of my favorite handgun hunting loads for revolver or semi-auto) to provide more penetration & weight retention than other JHP designs, combined with expansion to about 1.5 caliber. In a 10mm it would be my choice as the best compromise for both barriers and soft targets. I'd go with the 180 grain XTP as opposed to the 200 grain for street carry.

Flop-Shank:  Thank you for the input.  The lure of the heavily loaded Magnum revolved is like a Siren calling my name.  I do love them.  Perhaps a .41 or .44 Magnum backed up by the Glock 20 in a shoulder rig sounds promising.

Chris:  Did you get the 180-grain XTP in 10mm in your gelatin testing?  How were the results?

Mas:  I will give Tarnhem a call about the Glock manual safety.
