correct load for G27 .40

Discussion in 'Caliber Corner' started by JDinNC, Sep 21, 2010.

  1. I want to carry the G27 and I like Gold Dots. In .40, they come in 155, 165, 180, and 180SB. Which one is the correct one for a G27? Thanks.

    The one that is the most accurate for you. They are all good loads

    The 180gr will likely have less "felt" recoil. They make a short bbl load, but it really comes down to what feels right for you. The G27 torques quite a bit & the lighter 155gr loads seem to be worse. The 165gr load is a good compromise for me.

    After testing four different weights...135 155 165 180...i chose the 165 gr. ammo. It worked the best for my gun and me and it had the least felt recoil.

    I carry 165 grain Ranger T-Series, and it shoots very well for me...

    I selected the 180 gr, works best for me.
  8. Sorry I worded it wrong. I know all 4 loads function in the G27. I was talking about ballistics. Which gold dot load has the optimal penetration and expansion out of a G27? like according to the FBI studies you read about sometimes. I've read that if you drive a certain hollow point too fast, it would expand too quickly and fail to penetrate. Or on the opposite side, if you drive a certain hollow point too slow, it would overpenetrate because it failed to expand. So which is the best choice out of this 3.5" barrel?

    I prefer the 180's, but it is up to you to decide that.
  11. started with the 180 then went to the 165. i think its a good middle of the road round that would give the best of velocity, expansion, and penetration. i haven't seen any data on it though.

    Have a G22 and G27. Carry the G27

    Use Federal FMJ 165gr and 180gr and Speer TMJ 180gr

    for carry ammo, Federal HST 180gr and Speer Gold dot 180gr

    Tried the HST 155gr, but did not really like it.

    HST so I carry the 180gr Speer Gold DOT or Federal 180 gr HST

    I'm not overly concerned with the velocity difference with the shorter barrel since most self defense situations are close range. I use the 180 HSTs but would be fine with the GD's or HST's in 165-180g. Both Speer and Federal use a 4" test barrel and rate the 180's as just over 1k fps, so I'm sure they'll do just fine out of the 3.5" barrel.

    +1. I prefer 180s in mine. I'd like to try the GDSB loads, too. If I could ever find them...
  15. OK I went with the 180SB. Thanks guys!

    I like 200 gr WFNGC Double Tap ammo. Bullets look like a little oil drum and regardless of velocity they will make a big hole and penetrate better than a HP. Before anyone brings up the overpenetration argument, a study showed that only 12 percent of bullets in LEO shootouts with BGs actually hit the target. The issue is not people being hit by bullets that pass through BGs, its people being hit by bullets that missed the BG all together. The percentage of people hit by bullets passing through a BG was very small. I don't have to worry about velocity, denim plugged HPs, etc.

    I prefer the heavier bullets in .40 so I chose HST 180gr or the Speer 180gr Short Barrel.

    Do you change out the barrel when you shoot the DT 200gr WFNGC ammo?

    No. Per Buffalo Bore if the cast bullet is hardcast (BHN of 21) then they say you can shoot them in Glock barrels. Double Tap is a little more cautious and adds a gas check to their 200 and 230 gr 10mm/40 cal bullets in addition to a BHN of 21. Hickok45 has a youtube video where the 10 mm Glock factory barrel doesn't stabilize the the 230 gr 10mm ammo but a Lone Wolf barrel does. If I changed out the barrel it would be for accuracy reasons if needed. That isn't a problem with my G27. If I were to reload I would get an aftermarket barrel as there is supposed to be less bulging of the brass in the tighter aftermarket chamber. If you don't plan on reloading and the Glock barrel is accurate with that ammo why buy a new barrel? Spend the money on ammo. As I have stated before DT offers their hardcast bullets for sale separately or in loaded ammo.

    The R&D engineers used the Glock 27 pistol when developing their "short-barrel" (SB) 180-grain Gold Dot .40 load. If you want any of their test info, send me a PM.
