Hmm so was checking out UMP45, these are the stats right now if I'm not mistaken.

Name - UMP45
Freeze - 0.1545
Firerate - 0.2825
Spread - 0.04
Clip - 20
Reload - 0.4
Bullets - 1
Auto - N
Stacked - N

It has 8.5 dmg according to it's description in the gun store...which means 9.5 when perfect???? I realize the extra 0.5 dmg won't really make any difference in spars because it still needs 6 shots to kill.
Also that freeze is really good and rate of fire very slightly better than m4. Now this gun will obviously be more towards skill play or whatever and could have hard time fighting against GM4/Ion spams but still it can definitely be a good gun if used correctly in spars right?? Also if you already have a shipka then is there much sense in getting this for spar ? Please elaborate what you think about this gun.
