Manufacturer: Glock 
Cost: $400 
Ammo Per Clip/Ammo Held in Weapon: 20 rounds 
Max Reserved Ammo: 120 Rounds 
Special Weapon Function: Switch Firing Modes 
Power: Medium (1 shot)/High (3 shots) 
Range: Medium-Short 
Accuracy: Medium 
Ammo: 9mm (20-round clips) 
Reload speed: Quick 
Cyclic rate: Very high (bursts)/Low (between bursts)/High (Semi Auto) 
Overview: The main pistol of the Terrorists (tangos), it is pretty accurate but deals less damage then it's USP counter-part. The three round burst really can make this pistol shine, though. 
 

(USP)
Manufacturer: Heckler & Koch 
Cost: $500 
Ammo Per Clip/Ammo Held in Weapon: 12 rounds 
Max Reserved Ammo: 48 Rounds 
Special Weapon Function: Attach/Detach Silencer 
Power: Medium-High 
Range: Medium 
Accuracy: Medium 
Ammo: .45 ACP (12- round clips) 
Reload speed: Fast 
Cyclic rate: High 
Overview: With a free silencer and a powerful caliber some would wonder if the Glock is useless, but the USP fails when compared to the number of rounds it holds. You can turn this into a fast firing demon by quickly tapping the fire button multiple times and aiming at the chest and head
 
 

(Desert Eagle)

Manufacturer: Magnum Research/Israeli Military Industries 
Cost: $650 
Ammo Per Clip/Ammo Held in Weapon: 7 rounds

Special Weapon Function: None 
Power: High 
Range: Medium 
Accuracy: Medium 
Ammo: .50AE slugs (7-round clips) 
Reload speed: Medium 
Cyclic rate: Medium 
Overview: With the penetration power of a G3 at close ranges, this baby packs a punch! A good first, second, and third round gun, or a if you just feel like kicking ass in style. A good choice for a back-up pistol as a sniper. 
 

P227

Manufacturer: SIG Sauer 
Cost: $600 
Ammo Per Clip/Ammo Held in Weapon: 13 rounds 
Max Reserved Ammo: 53 Rounds 
Special Weapon Function: None 
Power: High 
Range: Medium 
Accuracy: Medium 
Ammo: .357SIG (13-round clips)

Manufacturer: Fabrique Nationale 
Cost: $750 
Ammo Per Clip/Ammo Held in Weapon: 20 rounds

Special Weapon Function: None 
Power: Low 
Range: Medium 
Accuracy: High 
Ammo: 5.7mm (50-round clips) 
Reload speed: Medium-Slow 
Cyclic rate: High 
Overview: Deadly accurate, but no power to back it up. The FiveseveN's twenty round clip is good for killing off an enemy at long range. 

 Dual Elites (Terrorists only)
Manufacturer: Beretta 
Cost: $1000 
Ammo Per Clip/Ammo Held in Weapon: 15 rounds (30 for both weapons) 
Max Reserved Ammo: 120 Rounds

Power: Low 
Range: Medium 
Accuracy: Medium 
Ammo: 9mm (30-round clips) 
Reload speed: Medium-Slow 
Cyclic rate: High 
Overview: These weapons aren't very popular and don't serve a functional purpose. They're not powerful, not accurate, and not a good pair of guns. They look cool, though

 
(M3 Super 90 Entry)

Manufacturer: Benelli 
Cost: $1700 
Ammo Per Clip/Ammo Held in Weapon: 8 shells 
Max Reserved Ammo: 32 Rounds

Range: Medium 
Accuracy: Less accurate over distance 
Ammo: 12-Gauge shells (8-shell boxes) 
Reload speed: Medium 
Cyclic rate: Low 
Overview: The slower firing, pump action shotgun of CS, get up close and rip 'em up. A very under-used weapon, but a great one at that. At close range, this weapon is really deadly. Very useful. This weapon can't fire underwater. 
 

 
XM1014 (M4 Super 90)

Manufacturer: Benelli/Heckler & Koch 
Cost: $3000 
Ammo Per Clip/Ammo Held in Weapon: 7 shells 
Max Reserved Ammo: 32 Rounds

Range: Medium 
Accuracy: Less accurate over distance 
Ammo: 12-Gauge shells (8-shell boxes) 
Reload speed: Medium 
Cyclic rate: High 
Overview: The fully auto shotgun of CS, the xm1014 should be treated like the M3, only less accurate and faster firing capabilities. This weapon can't fire underwater.

(MP-5)

Manufacturer: Heckler & Koch 
Cost: $1500 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 120 Rounds 
Special Weapon Function: None 
Power: Medium 
Range: Medium

Nice good smg, considered gold by the S.W.A.T.

(TMP) (CTS ONLY)

Manufacturer: Steyr
Cost: $1250 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 120 Rounds 
Special Weapon Function: None 
Power: Low 
Range: Medium 
Accuracy: Medium 
Ammo: 9mm slugs (30-round mags)

This is a weak smg with a silencer.

(UMP)

Manufacturer: Heckler & Koch 
Cost: $1700 
Ammo Per Clip/Ammo Held in Weapon: 25 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: None 
Power: High 
Range: Medium-High 
Accuracy: Medium-High 
Ammo: .45ACP slugs (12-round mags) 
Reload speed: Slow 
Cyclic rate: Low 
Overview: The MP5-Navy's sister is powerful, but slow in reload and cyclic rate. Accuracy over speed may prove useful if you burst and take cover. Because of it's slow cyclic rate (the slowest in the game besides pistols), it proves useless. Unless this weapon is modified in the future, it's completely useless. Avoid it.

MAC 10 (T only)

Manufacturer: Ingram 
Cost: $1400 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: None 
Power: High 
Range: Short 
Accuracy: Low-Medium 
Ammo: .45ACP slugs (12-round mags) 
Reload speed: Quick 
Cyclic rate: Very High 
Overview: Pretty powerful and lacking accuracy, the MAC-10 is a typical compact terrorist weapon. It would fit the mold for a Terrorist TMP, but the MAC-10 is feared by many, and not considered a toy, unlike the TMP, which too many underestimate. 

(P90)

Manufacturer: Fabrique Nationale 
Cost: $2350 
Ammo Per Clip/Ammo Held in Weapon: 50 rounds 
Max Reserved Ammo: 100 Rounds 
Special Weapon Function: None 
Power: High 
Range: High 
Accuracy: Medium 
Ammo: 5.7mm slugs (50-round mags) 
Reload speed: Slow 
Cyclic rate: Very High 
Overview: Lovely SMG, this gun really relies on your personal preferences, you have to get used to medium accuracy for the high rate of fire, as above try it out. The fastest firing weapon in CS. It's fifty round clip will allow you to have a 20 round advantage over most enemies, if not more! 

Colt

COLT

Manufacturer: Colt 
Cost: $3100 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: Attach/Detach Silencer 
Power: High 
Range: Medium 
Accuracy: Medium 
Ammo: 5.56mm slugs (30-round mags) 
Reload speed: Medium 
Cyclic rate: High 
Overview: One of the most versatile guns in CS, you'll find yourself using this a lot. It's stealthy, semi-accurate, and packs quite a punch. The silencer is optional, but does decrease damage. The pay off, of course, is that you're basically inaudible from a distance and a bit more accurate. 

AWP

Arctic Warfare Magnum (AWP or AWM)

Manufacturer: Accuracy International 
Cost: $4750 
Ammo Per Clip/Ammo Held in Weapon: 10 rounds 
Max Reserved Ammo: 30 Rounds 
Special Weapon Function: 2.25x zoom/9x zoom 
Power: Very High 
Range: Very Large 
Accuracy: Very high 
Ammo: .338 Lapua (10-round mags) 
Reload speed: Medium 
Cyclic rate: Low 
Overview: This brings the term one-shot-one-kill to life in Counter-Strike, this weapons weak points are it's zoom out period to bolt the weapon, and it's horrible performance in CQB, or Close Quarter Battle. Duck and zoom for full accuracy, but a strafe and stop should get you enough accuracy to get most players. It should be noted that, due to an oversight, this weapon is usually called the AWP, Arctic Warfare Police, but it is actually an AWM, or Arctic Warfare Magnum.

G3/SG-1 Precision Sniper Rifle (Terrorist Only)

Manufacturer: Heckler & Koch 
Cost: $5000 
Ammo Per Clip/Ammo Held in Weapon: 20 rounds 
Max Reserved Ammo: 60 Rounds 
Special Weapon Function: 2.25x zoom/6x zoom 
Power: Medium-High 
Range: Large 
Accuracy: Medium 
Ammo: 7.62mm slugs (30-round mags) 
Reload speed: Slow 
Cyclic rate: High 
Overview: A semi-accurate, fast firing, and great looking sniper rifle from H&K. Not very accurate but you can get 5 bullets in your opponent before he hits the ground. Just hold down the trigger and let the bullets fly! Though, using it like an AWP with semi-auto firing, is much smarter. It should be noted that against any sort of good sniper/long range shooter, this weapon is entirely useless.

SG-552 Commando (Terrorists Only)

Manufacturer: SIG 
Cost: $3500 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: 2x zoom 
Power: High 
Range: Very long 
Accuracy: Medium (Bursts)/Low (Full Auto) 
Ammo: 5.56mm slugs (30-round mags) 
Reload speed: Slow 
Cyclic rate: High 
Overview: A huge rate of fire, envied by even the m249, the Commando's accuracy becomes lack luster when you go full auto. Shoot in bursts and/or zoom a lot, to control the your aim.

SG-550 Sniper Rifle (Counter-Terrorist Only)

Manufacturer: SIG 
Cost: $4200 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: 2.25x zoom/6x zoom 
Power: Medium 
Range: Large 
Accuracy: Medium 
Ammo: 5.56mm slugs (30-round mags) 
Reload speed: Slow 
Cyclic rate: High 
Overview: Less power than the G3/SG-1, a bigger clip, with everything else the same. The AWM is a much better weapon than this when it comes to sniping. Use this weapon for a more supportive assaulter role. Try to pick off assault rifle users from a distance, but be warned: The AWM dominates all. 

AUG

PSteyr AUG A1 (Counter-Terrorists Only)

Manufacturer: Steyr 
Cost: $3500 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: 1.4x zoom 
Power: High 
Range: High 
Accuracy: High-Medium (Bursts)/Low-Medium (Full Auto) 
Ammo: 5.56mm slugs (30-round mags) 
Reload speed: Medium 
Cyclic rate: High 
Overview: One of the most powerful Counter-Strike weapons, the AUG is accurate and very deadly, if you've got the money. Perfect for long range combat, whereas the M4A1 is more Close Quarter Battle oriented. This weapon has a good zoom, but don't try firing it at full auto as the scope will simply bounce around. 

AK-47

Avtomat Kalashnikov Model 47 (AK-47)

Manufacturer: Kalashnikov 
Cost: $2500 
Ammo Per Clip/Ammo Held in Weapon: 30 rounds 
Max Reserved Ammo: 90 Rounds 
Special Weapon Function: None 
Power: High 
Range: Medium 
Accuracy: High (Bursts)/Low (Full Auto) 
Ammo: 7.62mm slugs (30-round mags) 
Reload speed: Slow-Medium 
Cyclic rate: High 

Overview: A fast firing but inaccurate weapon for the average terrorist, get in close and take off their head. This weapon may be called inaccurate in some cases (like above), but it is probably one of the most accurate in the game if used correctly. Burst, duck, strafe. Aim for the chest and recoil will earn you a headshot. A deadly weapon. 

Scout

Scout

Manufacturer: Steyr 
Cost: $2750 
Ammo Per Clip/Ammo Held in Weapon: 10 rounds 
Max Reserved Ammo: 60 Rounds 
Special Weapon Function: 2.25x zoom/6x zoom 
Power: Medium 
Range: Large 
Accuracy: High 
Ammo: 7.62mm slugs (30-round mags) 
Reload speed: Medium 
Cyclic rate: Medium 
Overview: Need a cheap sniper rifle? Here's your toy! Duck and watch out for AWPers! The weapon isn't amazingly accurate, but a headshot will kill! If you kill someone with a scout, they'll be two things: impressed and disgraced. Arguably the true sniper rifle of CS, if you can own with a scout, you'll dominate with an AWP. The Scout takes skill, practice, and tactics. 

M249 PARA Light Machine Gun

Manufacturer: Fabrique Nationale 
Cost: $5750 
Ammo Per Clip/Ammo Held in Weapon: 100 rounds 
Max Reserved Ammo: 200 Rounds 
Special Weapon Function: None 
Power: High 
Range: Medium 
Accuracy: Medium 
Ammo: 5.56mm slugs (30-round mags) 
Reload speed: Very Slow 
Cyclic rate: High 
Overview: Holding a 100 rounds, being somewhat inaccurate, having a high rate of fire, and slowing the carrier down makes this gun great for laying down suppressive fire whilst ducking. Or, of course, you could rush and try to eliminate the other team with it. Chances are, however, that someone with an assault rifle will kill you, in the process making you look like an idiot. You can, however, kill from amazing distances if you use bursts
