I have a m&p9 and I like it, shoot smooth, feel less recoil /muzzle flip than the gen 3. so fast shooting and follow up
I know the gen 4 got some problems with the recoil spring but I seem it is solved with the recoil spring 4....
The backstrap doesnt seem to be big deal.
I am thinking about to buy a gen4 glock 19 and keep both guns..
but does the gen 4 has less recoil/muzzle flip because of the dual spring or is almost the same feeling?worth it to have 2 9mm almost same size.
I use my gun to IDPA, drill night, practice.. so I need to improve my fast shooting.. I like my mp9 cause this is smooth and I would like to test any other brand like glock..
