    I am debating about which one to CCW. I have a G21 right now, but that is obviously too big. I like the fact that the 10mm has the weight of the 45, and more velocity. What I like about the G32 is that I can switch over to a 40 too. Which would you guys pick, 357 sig or 10mm?

    Well I can't speak for the G32 but I do carry a G29 most days when i'm not working and it conceals pretty well however it is a little thick. From what I can tell, the G32 is built on the G19 frame which is the compact 9mm not the subcompact. This means its going to be a little longer and taller than the G29 but a little thinner and still carry 13 rounds as opposed to the 10 rounds in the G29. The G29 is the same thickness as the G21 you currently have.

    Oh and you can convert the G29 to a .40 with a barrel change just as easy as the G32 so that shouldn't be the deciding factor. The 10mm is pretty snappy and I can imagine the .357 is as well so neither are going to recoil like a practice 9mm.

    I think what you have to ask yourself in this scenario is:
    1) Do you require a thinner frame than your current G21 and
    2) Do you subscribe to the super fast light bullet theory or the moderate speed heavier bullet theory. I know the 10mm is rarely referred to as the slow one but, in this case it is.

    A Glock 29 10mm gives about the same performance as th Glock 22 in .40 (that's a full sized Glock in barrel length.) And that ain't hay.

    The Glock 32, in .357 Sig, with such as Double Tap ammo does equal the .357 Magnum. And that's real good to.

    Which to carry? Either one! Both with full loads are real good so decide which fits your hands better and carries better for you. Then pack that one.

    You should be able to run 40 S&W & 357 Sig out of G29 with a barrel and mag swap.....so I say G29.
    10mm is the the way to go.

    Of the two.... G32 + a Glock 23 barrel.

    I like my G29 had it for years, but around here all you can get is water downed 10 MM if your Lucky. Not much better than a 40 S&W in many cases. Been like that for years. I generally have to order good good 10mm ammo $$ or handload it.

    Not exactly. The Glock 29 gives much better performance than even the full length .40 in the heavier bullet weights.
    The 170-200+ grain bullet weights lose very little velocity from a G29 compared to even a G20 (full size 10mm.) About a 50-75 FPS difference.
    The lighter bullets begin to lose more and the difference due to barrel length continues to increase from there as you get lighter bullets.

    The Glock 20 full size 10mm has a 4.61 inch barrel length.
    The Glock 22 full size .40 S&W has a 4.49 inch barrel, slightly shorter than the Glock 20's.
    The Glock 29 in 10mm has a 3.78 inch barrel.
    So the barrel length difference is less than 3/4 of an inch between the full size .40 and the compact 29.

    Take a look at a couple of Double Taps figures for their ammo, which tend to be accurately advertised:

    Bullet : 200gr Controlled Expansion JHP

    Ballistics : 1250fps / 694ft lbs. muzzle - Glock 20
    1083fps / 521 ft lbs 100yds Glock 20
    Glock 29 - 1195fps Muzzle

    A difference of all of 55fps between the 20 and 29 in that loading.
    You certainly won't be firing a 200 grain .40 S&W at 1200 FPS from a Glock.

    Or the 180 grain comparison:

    Bullet : 180gr. Controlled Expansion JHP

    Ballistics : 180gr. @ 1350fps/ 728 ft/lbs- Glock 20
    1136fps / 516 ft lbs 100yds Glock 20
    Glock 29 - 1270fps

    80 FPS difference, but still 1270 from the Glock 29, well beyond what you will get from the full size .40.

    You also said:

    The .357SIG is in most loadings less than the .357 magnum.
    The .357SIG is also based on the .40 S&W case (itself based on the 10mm) and is merely a .40 S&W necked down to 9mm.
    The necked down version of the 10mm is the 9x25 Dillon, which is actually more powerful than the .357 Magnum in many loads.
    Drop in barrels are available for 9x25 Dillon for the Glock 20 and 29.

    And to the OP, you can switch over to the .40S&W, .357SIG, or 9x25 Dillon in the 10mm models very easily as all of the brass is the same diameter, the extractor engages them all the same, and a quality drop in barrel is available for each.
    With the .357SIG model Glock (9mm frame) you must stick with the shorter rounds so only .357SIG or .40S&W.

    10mm is awesome if you can afford to shoot it. At a shop close to my home a box of 50 Blazer 9mm is $11.99 while a box of 10mm is $26.99. And this is aluminum case Blazer. I know you didn't ask about 9mm but....just sayin'.

    I have both and the 29 weighs a ton. Get the 32 and a 23 barrel, you'll want it unless you can find some reasonably priced 357sig target ammo or load your own. Good SD ammo is the same price.
