    I buying either a Glock 34 or 35, and then am going to customize it to the hilt for a range gun. The sole purpose of this gun is for having fun at the range and accuracy. So my question is:which caliber is more accurate 9mm or 40sw. I know I can get some $1,500 Kimber or something like that, that will proabably be more accurate, but I am set on building the Glock. Is there an accuracy difference in the 2 rounds? Any one have experience with this? Thanks for your time, this forum has been a tremendous help to me and my hobby.:)

    Neither will be more accurate. You could magnaport the G35 and reduce the muzzle jump alot. I had a G17L that I loaded hot for pin matches and it jumped more than normal store bought 9x19mm ammo. I had the barrel magnaported and it made a huge difference.

    Dont get an imitator!! Get real magnaorting. them guys know what they are doing and you will keep the extra jump of the 40 down to 9mm levels. magnaorting also does not add much if any more noise.

    Or get a 34 and do the same and be amazed at how flat that front sight stays. Nice thing about the G35 is you can get a 9mm barrel.

    I am not a 40 fan at all but you can get the 40 and build a 9mm slide and have two guns on one frame.

    Just a few thoguths. I would go 40, trick it out AND get a 9mm uper............

    I don't know of any inherent difference between the two rounds. If you're not a reloader, then the 9mm is the only way to go. If you do roll your own, then you can just pick whichever you want.

    9mm. Its cheaper to shoot and easier to get (some times) . 40's are snappy (yes on the glocks too) so they have a tendency to no be so much fun for just range use. People at the range always rent 40's and end up switching to something else 9mm usually bc the 40 is uncomfortable over time to them:rolleyes: Except the FN40. For some reason it don't feel like a 40.

    Id take the 9, never much cared for the .40. It recoils almost as much as the .45 and doesnt hit as hard. The 9 recoils half as much as the 40 and hits almost as hard. Plus with my mad skillz id could shoot em in the eye at 50 yds.. :D JK.. ha ha... not really;)

    What exaclty is magnaporting? I was thinking about having a 6.5 inch barrel with a threaded on compensator. I looked at ported barrels and think that the compensator might work better and add a sweet look to it. Thinking I will go the 9mm route with the cost of ammo and the fact that the 9mm overall is much more mild. I mean, I have a 10mm for the times I want real knock down power, so if accuracy is the same, might as well shoot the cheaper and more plentiful ammo, right?

    I carry a .40, but if I was sticking to the range I'd go 9 for sure. Less recoil, cheaper, no inherent difference in accuracy that you will notice. What's not to like.

    I don't think either one is more accurate than the other, so if strictly for range work the 9mm gets the nod based simply on lower ammo cost and better availability.

    Magnaport international, the home of Larry Kelly ( God rest his sole ) is about 20 miles from me. I have had many Shotguns ported and choked here. very professional and reasonably priced.

    I like the 40. But I like the 45 the best so...

    I am a bit more acurate with the 9 than the 40 but that is me. If just for the range then 9 all the way even rolling your own its cheaper than the 40.

    If you shooting slow fire there won't be any difference between the 9mm and the 40 S&W. During rapid fire the 9mm is typically easier to control with all things being equal. If your generally new to shooting I would suggest getting a 9mm. Practice ammo will be cheaper and that will increase your accuracy more than any inherant accuracy difference.

    Shot a .40, felt good, hit good, but really didn't see any point in the .40 round. 9mm is very easy to get and cheap. At the time, I had a 9mm already, if I wanted I'd get a .45 before I'd get a .40. Just my 2
