When I got my first M629-5 Mountain Back Packer and "Vette75" and on this forum can attest to this... I met up with him at the Silhouette Club he goes to and is very active at... I'd only shot the "MBP" once, maybe twice before... Silhouettes are spaced from 20Meters, 40Meters, 60Meters, and 80Meters on out until 100Meters... This was my first Silhouette Match at that... and I did pretty darn good my first time out slinging Factory Loaded 300grain Prvi-Partizan loads rated at 1289fps and almost or even over 1000ft-lbs of energy. I think I got about 70+% hits that day. Members kept asking what ammo I was using because my targets fell so hard and more than a couple times fell 2 Silhouettes with 1 shot those 300gr Prvi-Partisan's hit the Plates and their Rail-Racks so hard.
So to answer your question, the "MBP" is very recoil manageable up to about 100 full-house rounds is exactly what I will testify too as being very comfortable for me with the 3" barreled M629's... of which I've done many times either an extended range session or 3-4 rounds at a Silhouette session/match in a day.
I do wear a nice pair of "Cop-Style" svelte leather gloves that in no way hinder, are padded, nor bulky... Just good cut, double stitched, quality leather made XL sized gloves of which "Vette75" can attest to as well.
ETA: I forgot to include... My M629-5 "Does Not" have any Barrel-Porting...
