Best pistol I've used is my own SRC Tokarev TT-33. Comparing to my friends Glock 17 (Don't know the manufacturer), the main differences I noticed were feel and weight. To me, the Glock seemed bulky in comparison and although the grip is more ergonomic (TT-33 having just a straight shaft akin to 1911s), the Tokarev just slots more nicely into my hands. And the Tokarev is noticably slimmer, and although it makes the iron sights a bit more crammed together, it feels alot nicer in my hand.
Now, I'm not sure what fps the Glock was firing at, but the Tokarev out of the box fires at around 280fps, I'd say perfect for most CQB encounters. Not suitable as a main backup weapon, but still bloody good in the right scenarios.
Now, the drawbacks. The main drawback is the mag lips. They are made of rubbish plastic and if you force the mag into the gun, they WILL break. And if you pull the BB feed down and let it ping all the way up, it'll also break the mag. So be careful when loading rounds and when you insert the magazine, be sure to hold down the mag release button and give the mag a little tap to make sure it's in right. I've heard there's upgraded mag lips availible from Airsoft World, but I haven't had a look at them/used them so I cannot say anything about them.
The main drawback is that it's a limited edition piece. 600 worldwide. So you may not be able to find one. But if you do, I reccommend picking one up. They went for £110 on Airsoft World when they were in stock, but you might be able to pick up a bargain from somewhere.
