similar to ppk? Felt recoil comes from
1-Total mass of moving parts-slider,recoil spring rod,if moves then also the barrel
2-bore axis
3-grip
4-recoil spring
bore axis is 11mm..the nearest gun is striker one with 12mm
slider and rod weight is 200 gram...a normal slide weights over 300 gram
you can grip the gun from the front side,because of no moving parts..
a double stage recoil spring stop the slide very smoothly....There is alot of difference with ppk
