45 ACP 21,000 PSI
45 ACP +p 23,000 PSI
45 Super 28,000 PSI
460 Rowland 38,000 PSI
10mm 32,000 + a bit

The steroid version of the 45 ACP is the Rowland which is being set up as kits in ever smaller and lighter packages . The only problem I have with the gun is that they always seem to end up in essentially the same size gun as a .45 ACP. The 10mm shoots flatter and seems to have more of a selection of deep penetrating bullets, which only works if your planning to be outside of 90% of most shooting incidents and you are shooting something heavy bodied.

I'd rather have a 45 type for home defense. too big for practical concealed carry and a 10mm with 200 grain loads if I needed to discourage a black bear or test my handgun skills on hogs. The Dan Wesson is a very nice 10mm for anyone who likes 1911 types.

    Re: 45acp Or 10mm

    My carry gun is a Colt Delta Elite 10mm from the 1990's. The 10mm is a great round, especially in the heavier bullets. So I am a huge 10mm fan.

    However, I believe this thread was originally about a carry gun. So I assume that we are talking self defense and not sport hunting. If this is the case, then I have no problem whatsoever with the 45 ACP. No, it is not the hot rod that some of the other calibers are, but against the human body - it gets the job done.

    45 ACP ammo is readily available in a wide assortment of bullets, while 10mm ammo is tougher to find and more expensive. If this were my first carry gun, I would probably choose the 45 ACP or the 40 S&W over the 10mm. Recoil with the 10mm can be substantial. I believe that is how the 40 S&W came into being. A few gov't. agencies (FBI, SS) originally went with the 10mm as their new service piece back in the 90's, but many of the agents couldn't handle the recoil. So Smith & Wesson cut down the 10mm and put less powder in it and viola: the 40 S&W was born.

    Now, if we are talking a hunting/woods back-up piece for critters, then start at the 10mm and work your way up from there.

    recoil spring. It is not as powerful as the Rowland but you dont have
    to get a barrel extension with compensators to use it.. That requirement
    for Rowland removes all possibility for carry use.
    The only thing that requires a little caution is that it should be a good quality 1911 type, not one of the imported models with spot hardening and low grade cast parts or early dimension ejector and timed to ACP pressure.

    STI did a 10mm 6in with their tactical(railed) frame in an 1911 magazine. beautiful gun. The magazine also covered the Kimber 10mm.

    When I researched the Rowland and Super loads, I found to make my Springfield Loaded Stainless a Super, I just needed some springs from Wolf. To make the Rowland, I can get a kit from Brownell's. The Loaded has titanium firing pin and flared ejection port.

    I like the 15rounds the G20 offers. But the XD(not a candidate for Super or Rowland) offers 13+1 and Para (not a candidate for Rowland, they stopped making kits last time I looked) offers 14+1.

    If you follow the link from several messages back you will read the
    review of the Alaska Outfit called Wild West guns who is currently
    selling the Rowland Kits for the Springfield XD and the M&P 45 pistols.

    What is notable about their kits as opposed to all Rowland kits of
    the past that I am aware of is that they are offering a plain barrel
    in 5 or 6 inches without the compensators.

    Basically they are taking 45ACP and loading them up to 9mm or
    40S&W chamber pressures. Really Awesome in my mind. I assume
    the XD and M&P pistols may be inherently stronger than the
    1911 platform. Most likely they dont use the barrel link like
    the 1911 does.
