    Thinking of adding another Glock to the family. The more l read about the 10mm the more l like it. I would go with the g29 if went that route. Was going for the g30 because l have always believed .45 was probably the best bg stopper. Any opinions either way would be helpful.

    I would probably lean towards the G30 because with the cost of ammunition I would/do shoot it more. Also I do not feel it necessary to turn anything into molten glass...

    I have the G29 and the G30. Both are great, especially as carry guns, but the G30 is cheaper to feed. And .45ACP ammo is more readily available.

    The perfect solution for me is the G30SF 45ACP for a defensive, CCW/HD pistol at a range under 25 yds. which can be quickly converted to 10mm with a 45-10mm conversion barrel and G29/G20 mags for woods protection and offensive work beyond 25 yds. While the big-bore .45 is reassuring for personal defense, the relatively flat trajectory and greater energy of the 10mm round (compared to 45ACP) makes it quite easy to get accurate hits out to 100 yds with a red dot sight for the pistol.

    If you like, a 4.70" extended 45-10mm conversion barrel is available from KKM for the G30/30SF; longer than the stock G20 barrel at 4.61".

    The .45 Super round is also a good choice for woods protection and hunting with a Glock. One of my pistol instructors hunts deer with a Glock 21 and .45 Super ammo.

    Best of luck to you in making your decision.

    Im in the same boat as you OP. I want to get a big bore Glock. I'm leanin toward the G21 though, and I'll get the 45-10mm conversion kit for bear country if I ever find myself out there.
    The G21 is just a classic .45. Get some arredondo +4 mag extensions and you've got quite a setup. Now the only hard part is finding a G21 SF RTF2!

    I've got two G-21's that are also set up for 45 Super. This leaves me with absolutely no need to rush right out and buy a 10mm.

    Im going through the same.....

    I am either going to get a G21sf or a G20sf for my next gun......

    I think i will finally go with the 10mm, just because it is the biggest/baddest of the Glock...

    i already have my ccw guns covered....now i just want something that gives a big BOOM

    edit: and seems like ammo is just as expensive whether 45 or 10mm...

    How do you correctly set up a G21 for 45 super? Just a recoil spring change?

    I'd vote for .45. I love my Gen4 G21 and the long range plans include a G30 to go with it.

    G20 or g29. You can convert to .40 or .357sig I believe. And .40 is cheaper to feed than .45 and 10mm. 100 round box at Walmart for $26!

    Here is an interesting thread on the subject:

    45 Super Chrono/Recoil Spring Data G30/G21C

    Just a 21 lb recoil spring works well for a G30 and G21 to shoot .45 Super. I suggest a stainless steel guide rod to go with it. I'm interested in the set-up Arc Angel uses for the G21 and 45 Super.

    I have a G21, and if I ever thought it would take something more than 14 .45 rds to get the deal done, I would bring my 870... ;-)

    .45 is cheaper, and readily available, and in the future those two things will be vitally important.

    It's pretty nice
    That's good advice right there.

    .40 is cheaper than .45 and you can shoot 9mm, 357sig and 9x25 from your 10mm. I use Pearce +2 extensions with 10 rd. Glock 30 springs in the 10 rd. 29 mags with 100% reliability. You now have a 12+1 compact 10mm, the same size as a G30 with 10 rd. mags.

    I also put a 36 upper on the 29 frame and use with G30 mags sometimes. I like both cartridges but if you want to get a 10mm - scratch that itch!

    I have both. IMO you cannot beat the G29 for power and concealability.

    10mm, underwood ammo is full power and reasonably priced, the "10 is too expensive to shoot" is just stupid

    This ^, cost of ammo is no longer a valid argument.

    If you're going to go the route of many 10mm enthusiasts and get a Lonewolf Barrel and Slide, I'd bet a 21 and then you'll have the ability to shoot both calibers.

    .45 is great for self defense, but it is lacking in the woods. The bigger diameter makes penetrating animal hides and skulls a craps shoot.

    Okay, the .45 is not a S&W .50, and I have not shot many critters in self defense in the woods or in the streets, (Put many a carcass in my freezer though on purpose!lol) but I sure pity the poor fool in either place that gets popped with a hydra shock round having been dispatched from my G21...

    I live in N Idaho, on acreage, bordering a national forest, and yes there are bears wolves, coyotes, moose, and elk, etc., ...any of which who were having a bad day would do an unarmed man potentially some serious damage.

    I carry the G21 in those very woods and fear not.
