i will try to address several of the questions posted in the thread about firearms and their use underwater. First off, yes a glock CAN be used underwater safely and reliably. The ONLY caliber that can do this safely this the 9mm( glock,17,19, or 26) and the ammunition MUST be subsonic nato spec. ammo.
HOWEVER in order to do this a few modifications need to be made. In order to guarantee reliability the following upgrades are recomended.
marine cups( not necessary but they help a little)
high torque firing pin spring( this is probibly the most important thing you need to prevent lite strikes on the primer)
12 lb ny trigger ( a stock 8 lb trigger will do but a heaver trigger will help guarantee safety in the water)
UNDER or - power recoil spring (a stock recoil spring is 17 lbs, replace it with a 15 or 13 lb one i recommend the 15 this will help to compensate for the use of subsonic ammunition and the added hydrolic pressure to ensure the gun will cycle reliably)
stainless steel barrel(this is a stronger barrel than stock and it is corrosion resistant)
replace steel internal parts with titanium parts, slide release,trigger assembily,firing pin,firingpin safety,recoil spring guide rod( this upgrade is STRICTLY to make the firearm more corrosion resistant)
total cost
glock $500-650
recoil spring $12-25
stainless barrel $85-250
marine cups $4-15
firing pin spring $3-12
ny trigger $30-50
titanium parts $200-300 (NOT necessary and they DONT affect the reliability)
NO gun manufacturer that i have EVER seen will warranty or guarante a gun for underwater use UNLESS the firearm is designed specifically for the purpose( the russian " aps underwater" being the most noted)and unless you are in law enforcement (swat,srt,federal)NOT a street cop or specialised military applications you have almost no chance of getting one legaly.
Any gun will fire underwater (once) the trick is to be able to do it safely and reliably.
glock 17 underwater firing specs.( subject to change due to ammo and environmental
changes)
12-14 feet it will penetrate 1/2 inch of plywood
4 meters the concussion will mame or KILL
12 meters the concussion will stun
out to around 25 meters it will scare most anything in the water
RULES required for safe underwater firing
you must purge the gun of ALL air (lock the slide back and with it submerged shake it around till all the air is out of it)
when firing you need to make sure that everything you DONT want to hurt is clear (clear a 240 degree area from the muzzle)most of the concussion is directed foreward however some of it bleeds to the sides and can cause harm.I cannot stress enough how strong the concussion will be in the direction you are firing, you dont have to hit it to kill it.
King Neptune posted "Or you could buy a REAL gun" in refrence to owning "GLOCKS"
My answer to you is simple. You have no idea what you are talking about.
I have been a gunsmith for 13 years dealing EXCLUSIVLY with the law enforcement
community.Simple FACTS about glock pistols since you dont seem to have any.
60% of the WORLDS law enforcement use glocks (over 80% in the USA )
the following USA agencies issue glock as a STANDARD sidearm N.Y. pd, Miami pd and the L.A pd just to name a couple:05:
30 coutrys use glocks EXCLUSIVLY for their military (including Australia,Hungry,germany,and the "new" iraq is being issued them BY the USA)
It has been rated number 1 production pistol in the world for the past 7 years based off a rating system that compares reliability,versitility,cost,and customer support
There are 2 reasons why the USA military is using beretta 92 series and not glock
1. (this is the main reason)when the military started taking bids for a new combat pistol glock didnt put a bid in due to some confusion (see reason 2)
2. part of the mandate the military set required that the pistol have an external safety(this has now been revised due to the fact that it has now been proven that a gun doesnt have to have an external safety to be safe)
The second thing you said, and this is what leads me to believe that you have NO idea what you are talking about.
You made a refrence about a "wet"silencer.
When a silencer is refered to as a wet/dry silencer it has NOTHING to to with water.
Wetting a silencer is when you coat the wipes in a lite layer of oil to aid in suppression.
Most SUPPERSSORS (silencer is slang, suppressor is the propper term) are designed to withstand water HOWEVER they will NOT work underwater (due to the fact that they require AIR space to catch the expanding gasses)
There are 3 things that make sound when you fire a gun.
1.sonic boom (bullet breaking the speed of sound, subsonic ammo fixes this)
2. expanding gasses (this is what a suppressor HELPS to quiet down)
3.mechanical noise (the hammer or firing pin striking the primer,and the gun cycling
, some firearms try to quiet this noise , for example the h&k usp has an option that locks the slide so when fired the slide wont move)
If you are going to say something please make sure you know what you are saying and you have FACTS to back it up.
Im not sure if links are aloud in this forum so i didnt post any ( if i find out i can ill post alot in refrence to glocks and other diver friendly firearms)
questions or comments email at
tsparks72001@yahoo.com no spam please(not that i get any
Hope this helps with your question,
