Thanks to Bigfoot for the cs weapon guide. Geist and Jeffrey Lau, for the additional detailed weapon stats. [SO]Tikka for the crosshair screenshots, and the CS team for the use of their weapon images.

Sub-Machine Guns

MP5-Navy

Manufacturer: Heckler & Koch
Cost: $1500

Detail : The most popular weapon in the CS game, deceptively useful for one so cheap. Picked by most people in the 2nd round (when usually everyone has enough money to buy it) it can also be a good 1st weapon regardless of the round if your trying to save money for your favourite gun. It has a slight kick back but its fast firing rate make it deadly if aimed well in close-mid range combat and useful against any opponent.
When to Use : 2nd round of the level, on maps where you rush the other team or as support/cover for snipers.
When not to Use : On Maps requiring accuracy over distance.
Try to Remember : The fast firing rate means you will run out of ammo quickly, try not to hold down the fire button unless you have a clean line of fire.

The MP5 Navy remains a very popular weapon in Counterstrike, it is effective in every situation bar long-range combat, its high rate of fire and moderate damage make it a great choice for its price. It has been downgraded slightly since Beta 6.2, as it was deadly, although its power has been reduced and recoil increased a tad, bursts of about 3 rounds will do the job nicely at longer ranges, up close, you can afford to go full-auto, and always remember to aim for the head! Overall, the MP5 is a good, solid weapon.

Steyr Tactical Machine Pistol (TMP) (CT's only)

Manufacturer: Steyr
Cost: $1250

Detail : A cross between the MP5 and the pistol Counter Terrorists Start with it spits out bullets very fast and very accurately for what is the cheapest "2nd stage" weapon. The lower kick than the MP5 means that it is favoured by LPB's as they can use it swiftly an accurately just like the pistol.
When to Use : 2nd round of the game, when your not in the first wave of the attack.
When not to Use : Later on in the level, against more advanced weapons.
Try to remember : 90 rounds go fast at the rate this gun fires, make sure you have full ammo before entering any hot spots on the map.

Steyr Tactical Machine Pistol (Silenced). By Geist (description) and Jeffrey Lau (stats) Details about how stats are calculated here.

*Steyr TMP
Cost: $1250
Type: Sub-machinegun
Max ammo: 30 | 120
Reload time: 2.09
Number of shots per second: 11.06
Damage: (9, 5)
Shots to kill: 12
Kevlar penetration: 1.80
Recoil type: Simple (just a bit).
Features: CT only. Silenced.
Changes: None.

The cheaper Steyr is not as powerful as the MP5, but still worth a purchase if you're strapped for cash at the start of a round. It has a slightly higher rate of fire than the MP5, and so almost makes up for the dip in power. The silencer (which is non-removable by the way) gives the Steyr great merit for stealth, with it, you can quickly sneak up to an enemy, spray them with bullets and retreat before the rest of their team knows whats happened.

FN P90

Manufacturer: Fabrique Nationale
Cost: $2350 

Detail : The most expensive of this type of weapon, it almost costs the same as the cheapest Rifle available (the AK47).  Reason for this is that it spits out bullets faster than any other gun available, and carries a massive 50 bullets per clip. Whilst they won't do as much damage as other guns, it's a very powerful weapon for close combat and those with lower pings as well as storming positions.
When to Use : On levels where the Rifles aren't much use (smaller ones, with less open ground), when your connect is good, levels where close combat is likely.
When not to Use : Over Long distances in rapid bursts. It's not very accurate when you press that trigger down hard :).
Try to remember : Bit of a kick back, so don't fire too fast or your accuracy will plummet. Reload time is also long, so stock up when you can and don't allow yourself to be caught reloading.

ROF.

The P-90 is a mixed bag of tricks, sometimes seeming useless, and sometimes seeming lethal, never as popular as the MP5, but it can still cause serious damage if you are willing to take a few rounds to get used to it. The huge rate of fire causes a big recoil, so you must take that into account when using it, a good tactic at close range is to aim for the torso, and let the recoil carry the gun up to the enemies head, with the high damage the P-90 causes, they will be floored in seconds. With more distanced combat, the usual burst firing tactics apply. But the reload rate is quite slow for an assault weapon, and many have died because their opponents have heard them empty the magazine, then just ran round the corner and killed them while they are helpless. So always remember to keep a full clip and reload when safe, because the ammo advantage over the other SMGs means that in a straight fight, they will be running out of ammo before you.

Ingram MAC-10 (Terrorists only)

Manufacturer: Ingram
Cost: $1400

Detail : Added in Beta 6, it has yet to win many fans. It feels like a heavier version of the Tactical Machine Pistol, but doesn't do as much damage as you would expect. Deceptively accurate over long distance, its main use really though is in close quarters combat where it can do a bit of damage if used in short controlled bursts. As it is T's only, might be a reasonable weapon to choose for 2nd rounds but many people now seem to skip this class of weapon on certain maps where only this is available to T's and not the MP5.
When to Use : Early on in the game, as a 2nd stage weapon.
When not to Use : On Maps where accuracy is required, and sniping vantage points are common.
Try to remember : Get in close with this one, and don't get trigger happy.

*Ingram MAC-10
Cost: $1400
Type: Submachine gun
Max ammo: 30 | 90
Reload time: 3.34
Number of shots per second: 12.74
Damage: (13, 8).
Shots to kill: 8
Kevlar penetration: 1.63
Recoil type: Simple
Features: Terrorist only.
Changes: None.

This Terrorist-only weapon is the alternative to the Steyr TMP, it is similar in performance, but a tad more powerful, so a lot of what has been said about the TMP can be said here. If you concentrate on headshots, burst firing, and don't try any long-range combat, then give it a try. But most people prefer the superior MP5 which is only an extra $100.

H&K UMP .45

Manufacturer: Heckler & Koch
Cost: $1700

Detail : Very similar to the MP5 navy, although the UMP holds less shots per clip and takes ages to reload, but each shot packs more of a punch than the MP5.

Cost: $1700
Type: Submachine gun
Max ammo: 25 | 200
Reload time: (around) 5
Number of shots per second: 9
Damage: Unknown
Shots to kill: 6
