my buddies and i tried a recoil measurement device on both a UMP and MP5 and the UMP has 15-16% less recoil.and its only 3% louder
>>65386849>uses accelerometer and sound meter>didnt take evidence Shit scientist
>>65386849The French police use UMPs
>>65386849>and its only 3% louderwhat do you mean by this exactly? decibels are logarithmic
The only PCC that's going to have more recoil than a UMP is a 10mm KelTec Sub2k
what is this revisionist history about the UMP? It's shittier than the MP5 in all regards
>>65387001It has better ergos and better optic mounting. Literally everything else is inferior. Personally I can live with the MP5 cocking lever and once you do get an optic mount on it you're set for life, so neither of those are worth dealing with the UMP's nightmarish recoil impulse.
Stupid frogposter.
>>65387109>>65387030>>65387001idk what to tell yaVidya lied
>>65386849And it's only much less reliable and when you try to suppress it it runs like even more shit.
>>65387030>ergosThis. The UMP is my favorite airshit gun
>>65386849>and its only 3% louderWTF does this even mean? An increase of only 3dB doubles the sound energy, and an increase of 10dB registers as TWICE as loud to your ear. So, 3% of what?
