UGGGHHH!
You can get used to full house loads in a 29 if you shoot enough. When I decided to carry my 6" 629 on duty I shot the heck out of it to make sure I was competent with it. I shot many Dept. supplied factory magnum duty rounds and many I rolled myself. I got to where the magnums weren't an issue at all. I did have rubber grips on it. Unfortunately my gun suffered from all of those magnum rounds.
I now also have a newer 5" with full lug that I use when I have the itch. I also have a 6" N frame 357. It's very pleasant to shoot but I think I like my 686's better. Lately I've been shooting mostly 38s in my 686s as I no longer have a free ammo source and I've shot up all my magnum rounds both factory and hand rolled.
Yes, there is considerably more felt recoil from a 44 mag as compared to a 356 mag, all else being equal.
Let me add that I have a Ruger Super Blackhawk in 44 mag that I don't like to shoot. It has the dragoon frame and the trigger guard just hammers the heck out of my middle finger knuckle. Other than that it shoots great.
I used to fight a flinch, an over analytical dude,, weighed about 145lbs when I graduated High School... I had a 1969 Garnet Red Z-28 with black stripes,, I loved the Python and model 27, but didn't have a spare dime after buying gas for the Z...
I did sneak my Dad's little .25 Beretta out to the junk ditch and light off a few rounds at our old washing machine... as "Dirty Harry" said, "a man's got to know his limitations...
First round took the top of my strong side thumb, "clean off!!!" as Harry would later remark about the 44 Magnum... but the .25 merely dented the old washing machine, (yes, they were so much better back then),, like the 1969 Z-28!!!
anyway, I went to a community college, again, NO MONEY! and my Dad started a flying club off the neighbors farm... flying the 172 was 14 bucks an hour, and my instructor was 8 bucks an hour.. so NO Money at ALL!
anyway, I had a few kids when I was able to purchase my first 27-2 off the "Gunlist", that gorgeous, beautiful, "Christmas Catalogue", that you could buy all year long..
so yeah, I flinched a LOT,, oh I could hit sometimes, LOL.. fortunately Dave Peterson my best friend, was a bigger Gent, and LOVED the 44 Magnum,, he started with a nickle 4" 29-2, and was a minor league baseball umpire at the time.. He sent the 4" back to Smith for a 6" tube, and continued on his merry way, firing quick double taps, was no big deal for him, but he did confess he occasionally got a case of the yips...
which honestly helped me a lot, we shot together, every chance we got, which also helped me a lot.. so yes, the 44 Magnum will kick the ******* right out of you, the 357 is fairly pleasant in comparison, but the sharp report, and snappy recoil, could still give you a case of the "yips"...
I ended up around 215lbs prior to my heart attack and triple by-pass, but recoil was a lot better... so everything kicked a lot less when I was a big, strong, farm boy, LOL
Buy good "EYE" protection, then buy equally good "EAR" protection, and finally get a good pair of actual shooting gloves!
