The new clan TMP came out and when I saw the complaints, I did some tests and some research on the TMP and all that.
The TMP damage is the most outcry in the community, with the 3 shots to kill functions. However, the TMP in real life uses the 9mm, but in the game, the description said 'improvised' ammo, which means the TMP does not use the weaker 9mm but the more powerful .45 caliber around-this justified the damage done.
In real life, the TMP is extremely easy to control and fire, justifying the very low recoil.
The TMP does not use a bolt-interlocking system, which means the the slide does not have to be cocked back when reloaded, only when you're ready to fire.
The TMP is a machine pistol, so it light weight allows it to be drawn out quickly.
When in character, you can see the character pull back a bolt on the TMP, the TMP does not have any bolt to lock. In the shop menu, preview the TMP and watch your character's preview, he'll pull a bolt back, when there isn't a bolt.
I-Tech, the TMP is to small to hold a common I-tech scope, it have to be custom made to fit the small size of the TMP. If you look closer, the I-tech is so big, it could not fit on the TMP, it sticks out of the gun like someone took it and glue it. The gun also lacks a Picatinny rail, which justified the awkward scope.
