LOL, I hear you about the weight issue.
I had a S&W model 29, 4" 44mag nickle. OMG was is heavy. Great to shoot 20rds.
Now days they make solid copper monolithic bullets in various sizes and they will easily pass through glass, vehicle doors and such and the bullet not be deflected so they are perfect for a truck gun protection or while on the road in a vehicle.
I even have a Sig P-365xl 9mm and I carry underwood Monolithic +P+ when needed.
How much penetration depends on how much powder is behind the bullet ❓
That is one huge reason I got the SA XDm Elite 3.8" compact 10mm, as I can carry CCW if need arises.
A shame SIG does not make a x-ten compact 10mm with their FCU or I would of gotten one of them.
A 10mm gives you more options on what to use for different purposes.
Do not discount the gud ole .45, as it still does have its advantages for those who luv their 1911 or 2011's
Wheel guns have their place as well but this threat was more about pistols.
The stopping power of both rounds are impressive, yet they go about it in different ways. The low velocity and heavy weight of the .45 and the high velocity, low weight of the 10mm both make for powerful shots. If you’re looking for speed, 10mm will have you covered. The 10mm has a faster velocity and energy than the .45ACP. But the 45 gives great diameter and has stood the test of time. Maximum damage becomes very handy when you’re in dangerous situations and the 45 is going to give you the largest bullet expansion.
- Muzzle Velocity: 1,008 fps
- Muzzle Energy: 406 ft/lbs
- Velocity at 100 yards: 917 fps
- Muzzle Velocity: 840 fps
- Muzzle Energy: 368 ft/lbs
- Velocity at 100yds: 792 fps
The bottom line: who pays for it, so long as you are happy with your choice, that is all that really counts.
