Heavy .40 Smith & Wesson +P Ammo - 155 gr. Jacketed Hollow Point(1,300 fps/M.E. 582 ft. lbs.) - 20 Bullet Box

All Buffalo Bore Heavy 40 S&W +P loads use flash suppressed powders that give high velocities at low pressures. Since over 90% of all human shootings in the USA happen in low light, we believe that flash suppressed powders are a potentially life saving advantage - you don't want to be blind after you fire one shot in a life threatening, high stress situation.

There is such a variety of 40 S&W pistols in public use that we will not determine what pistols are compatible with which 40 S&W +P loads - this is your responsibility! We will add that this ammo is safe in pistols that use a fully supported chamber. Please read the safety notices below. The first one is taken form the Speer #13 loading manual. The second is taken from Hodgdons #27 loading manual.

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 than 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.  The issue of Glock pistols not having a fully supported chamber is with the 40 S&W cartridge only, not 45 acp, 10mm, 9mm or 380 auto. While Glocks chambers are not fully supported in any of those calibers, only the 40 S&W brass is weak enough in the web for it to be a safety issue. I REPEAT, only the 40 S&W is a safety issue with chambers that are not fully supported. You do not need to be concerned with this issue when using our 45acp+, 10mm, 380 auto+P or 9mm+P or +P+ ammunition in Glock pistols.

Check out the velocities below that I shot with these loads in several modern pistols that I own. We don't believe that test barrels are a very real way of determining real life velocities out of real life guns that you will be using. So, as with all of our ammo, we use real firearms to determine real velocities.

Bought this for my Springfield XD 40 and it is the real deal! If your wondering whether or not it's safe for your glock i cannot say, but the springfield XD 40 can take it and say YUMMY "give me more of this hot load", I even mixed up 3 different 40 s

Great ammo hard hitting and low flash as described. Excellant customer service I emailed the Co. with a question on a Sunday afternoon and was shocked when I heard from Tim the owner within an hour. I still am in shock I will buy from Buffalo again and spred the word.

PACT MK5 Chronograph
15ft. from muzzle
Air temp: 92 degree
Humidity: 51%
Altitude: 558ft.
Glock 23 with a 4.0" Storm Lake Barrel: avg fps = 1212.225/505.7 ft. lbs.
Glock 22 with a 5.0" Storm Lake Barrel: avg fps = 1238.475/527.9ft. lbs.
Taurus PT 140 - 3.125" stock Barrel: avg fps = 1251.9/539.4ft. lbs.
Ammo is very consistent from shot to shot, from gun to gun. SD = 13! Unbelievable!!!!!
25 yds. Avg group = 3” (with all three guns...when I did my part)
I really am impressed that this ammo not only likes the stubby tubes, but it beats the longer ones in fps.and ft.lbs.
I really don’t like the profile of the bullet itself. Next test is; Clothing/Ballistic gelatin/and pork rib slabs.
That test will make my mind up to use this ammo for SD/Carry or not.
Look for my update after I perform my next test.

Shoot true, be safe, and introduce someone new to the wonderful sport of shooting.
