Hi guys:
I recently purchased a Glock G27 last month and am running all the major brands of defensive ammo through it to try and get the best accuracy with the highest velocity. It gobbles them all up without a hitch.
I bought some Buffalo Bore .40 S&W 155 grain at 1300 FPS. This is hotter than any .40 cal I have seen advertised. The next closest is Cor-Bon 140's at 1200 FPS. Anyway I fired a box of the BB through my G27 and it shot pretty good as far as groups were concerned.
Then I went back out on their web site and read about the ammo. There is a Safety warning about using this ammo with a Glock. It staes that the Glock has an unsupported head set up and that the case of the shell could rupture!!!
What exactly do they mean by an unsupported head? They are suggesting buying an after market barrel? I can't believe that this is a substantial weak point in the Glock when I see stories of guys running 80,000 rounds through their Glocks.
I cut and paste the safety warning below... from Buffolo Bore
______________________________________________________________
SAFETY NOTICE
"Some pistols chambered for the 40 S&W cartridge may not provide complete support of the case head. If this condition exists, normal pressure loads such as those shown here can cause the case wall to bulge or rupture at the unsupported point. Contact your firearm manufacturer to determine if your pistol completely supports the case head, or ask a gunsmith to inspect your pistol before using it with ANY ammunition. It is the gun owners responsibility to know his firearm and its capabilities and limitations."
40 S&W WARNING
"This data is intended for use in firearms which fully support the cartridge in the chamber. Use of this data in firearms which do not fully support the cartridge may result in bulged cases, ruptured cases, case head separation, or other conditions which may result in damage to the firearm and/or result in injury or death of the shooter or bystanders."
Glock happens to chamber their 40 S&W pistols without a fully supported chamber and both of those above safety notices are likely aimed at Glock. I know of no other 40 S&W handguns being sold in the US that don't have fully supported chambers. If you really want to shoot our 40S&W ammo in your Glock, have an after market barrel that uses a supported chamber, dropped into it. This is a fairly common practice and will give you the safety margin needed to fire our ammo in your Glock. It will also likely give you more velocity that the factory Glock barrel. I personally own two Glock Model 23's. Both of mine are going to get after market barrels dropped in so that I can use this excellent ammo in them.

Now tell me would you use this ammo in a stock Glock 27..???
