    Hi folks,

    I've just joined this forum and I've been impressed with the atmosphere of the readers!

    I've just bought a Smith & Wesson SW1911. I've been shooting a .22 Smith & Wesson 622 and decided to move up to a more powerful cartridge. I'm not a big fan of the 9mm. I agree with a comment in another thread that the 9mm seems to have a nastier kick than the .45.

    When I was younger, my dad and I would go hunting and if we didn't get anything, we would always practice with the .30-06 or his .22 rifle. I remember coming across a dump site and shooting old TVs with the .30-06. If I remember correctly, the bullet passed through the TV. My dad then filled a 4 litre bucket with water and shot it. The bucket turned to mist and pieces of plastic floated down.

    I bought the gun for recreational target shooting. Firearm regulations are pretty strict where I live. All I can shoot is paper targets at a gun range with the .45.

    I'm going to live my life vicariously through your answers.
    What can a 230 gr. FMJ bullet do? What effect does it have on other types of targets (metal, plastic, etc.)? I read that it can penetrate white pine up to 6 inches from 25 yards away.

    Is there some resource that gauges the strength of different calibres (ie. stopping power)

    Many thanks and I look forward to the responses.

    John Y,

    Congrats on the SW. I bought mine a little over a year ago and I absolutely love it.

    I found this one day. Not sure how reliable it is, but the numbers seem to match everything else I have read.

    Rgbegl, Thanks for the info!

    Keola, I absolutely love shooting the SW1911. How many rounds have you fired? Any issues at all?

    I've run about 2200 rounds through it so far. I've had a handful of stovepipes. I did have a problem with the barrel link housing not being cut enough which caused burrs in the housing and it also caused a mashing of the barrel which prevented the barrel from just free falling out of the slide. I took it to a gunsmith and he de burred it, cleaned it up and did an inspection of it to see if it was working properly. No problem since.

    Which 1911 did you get? The one I have is the 5 inch stainless. I was looking at the SC model and I passed on it. Instead I picked up a LTC. Love that one too.

    I have the 5" stainless too!

    Due to work and other things, I haven't been shooting too much in the past few years. As I mentioned in my opening post, I've been shooting a .22 (S&W 622) for eight years. It was time to move up. I wasn't following the latest gun trends and I was surprised to find that S&W was manufacturing a 1911. Anyways, I bought it right away.

    I've had it out a few times and it has worked flawlessly, except the sights.

    I was shooting down and to the left (7:00 on a clock face). At first I thought it was the way I was holding it or perhaps the increased recoil was throwing me off. I asked another fellow to shoot it and he did a bench rest and put three shots into 7:00.

    The Novak rear sights weren't aligned and after some bashing, the gun shoots true. In fact, my first shot after the sight was readjusted was right through the bullseye at 15 yards.

    Anybody have any tips on how to adjust the Novak sights? I let this more experienced fellow do it as I have no experience with the dovetail sights.

    Thanks again to everybody for their responses.

    I've never done it, but you could collect ½ gallon plastic milk containers, wash them, fill with water, and shoot through them.

    John, use the materials at your hands; the mateial, as long as it's consistant, mattersvery little; the consistency of placement, procedure, etc matters a lot. When it's all said and done, the majors will stack up like this:
    Penetration: 10mm/180, .38 Super, 9mm P, .45acp, .40 S&W
    Group size: .45ACP, .38 super, 9mmP, 10mm/180 , .40 S&W
    Effectiveness: (assuming a hard handed, recoil insensitive shooter): 10mm/180 (by a factor of about 50%), .45 acp, .38 Super, 9mm P, 40 S&W
    Assumptions are that all are shot in equivalent platforms, the only one availble, to my knowledge being the M1911, and that all are shot with industry spec ammo.
    Bud, if you can tolerate recoil, and repair expense, due to overworking a sound design, there is no more effective caliber around, for a self loading pistol, than the Original Recipe 10mm; if day in, day out reliability is the goal, with maximum downrange performance, both accuracy and ballistics, then the .45acp has it's day.
    The 9mmP is more efficient, and, with good bullets, almost as effective, also, availble in more platforms; it is not as well researched, practiced, accurate.
    .38 Super falls into the 10mm trap; i.e. few platforms, excellent external ballistics, excellent downrange performance, but all the good ammo is expensive, or rolled at home.
    The .40 S&W is my favorite whipping boy; most of the folks that shoot it, do so out of direction from their employers, or just plain ignorance. It will do nothing the .45acp won't do, but, at TWICE the chamber pressures; this was the "FBI's 10mm Lite" round, when their guys could not manage a 10mm/180, accurately, and durably.
    Hope this helps; I know it will stir up a whirlwind of controversy!

    Do a yahoo search for Clark Custom Guns, check out the .460 Rowland. which is only slightly longer case than the .45 ACP. Also do a search for Ace's Custom .45 Super. The 460 is actually more powerful than a .44 mag of the same size, using factory ammo. Standard .45 ammo is nothing much in the power category, but you can reload it to have 2-3x as much effectiveness.
