    For paper punching and pleasant to shoot I would concur, however some nice Underwood ammo at 1500-1700fps and 750fps is nothing to sneeze at :) though dang sure more expensive

    I heard they might have reliability issues for conversion barrels and shouldn't be used for self defense. I had a hard time believing it. It was on a gun review website showing top conversion barrels.

    Thoughts? Do I order lwa conversion 40 to 9 or kkm?

    Aim is the same. Point of impact might be a little off. Pretty sure the 23 uses a slightly taller rear sight than the 32, but anything 21' and under, the POI shouldn't be off by much, at all. Where you'd really see it is 25 to 50 yds, if you used a G32 with a .40 conversion. With a zero at 25 yds with the G32 stock sights shooting Sig ammo, or any zeroed sights, FTM, the 40 S&W would be a tic low at the same distance, hence the slightly taller rear sight for the G23. Now, when I say a tic low, that is what it is...a tic.

    eta - something to keep in mind is some sight makers sell the exact same rear sight for 9mm, .40, and Sig...no height diff.

    I did see that some make the same heights for all three. Not really understanding that but I guess it's what you get used to and learn to use.

    My best guess is at self defense distances, all 3 calibers are going to hit the same spot. Even out to 15 yds it's going to be very close. It's just not a distance where bullet drop begins to show up.

    Thanks. To be honest, when I go to the range I do not push the target out past 15 yards. I see others going as far back as possible with handguns but if I am shooting at someone at those distances or farther I hope I have my 357 sig and not my 9mm. A war will have definitely started, in that case.

    Thanks for the tip.

    I can tell you from personal experience people have been hit past 25 yards with a 9mm fmj and didn't live to tell about it. Just saying... lol

    For me shooting at 25 yards makes it easier when shooting at typical self defense distances. Anyway, I’m hoping that this .40 barrel will allow for some bulls at 25 yards.

    Plus it's just plain fun to shoot past 50 yds, especially when you can hit the target, or as in horse shoes...get real close. Gets a lot of raised eyebrows.

    My avatar is a 50 yd target done with a Gen 4 G34, rested.

    So...to get this straight. It's possible to have a Glock 20 or 21 and buy a conversion barrel to make it a 40cal or 357sig or a 9mm?? I had a G21 in the '90s and loved it. If this is possible I'll be buying a G20 or G21.

    So far as the G20 is concerned, you can get conversion barrels for .40, .357 SIG, and 9x25 Dillon, not 9mm Luger.

    I have the 10MM to 40 S&W conversion barrel from Lone Wolf for my 29. Runs 100% and shoots great.

    I'm starting to lean towards a 10mm conversion barrel for one of my 41's. It would be the 6" so I can thread it to install a brake. For range fun and bragging rights, only, but if it proved to be reliable with middle weight 10mm ammo, I could see taking a pig or two with it.
