I'll clarify things a bit about that Elephant in the room.
What you have been given WILL feel like a hand cannon first time you fire it, even with mild 147 grain target wadcutters. It's a consequence of any revolver that is very light in weight. Easy to carry does NOT mean easy shooting.
Specifically, that is why so many are suggesting that you get yourself a 22 caliber revolver so that you can aquaint yourself to shooting with a lighter recoiling handgun.
Now, there are some things that you can do to mitigate the recoil. One is to use your arm and hand to add to the System Mass of the gun when it recoils. This will require a very firm grip and a firmly locked wrist and elbow. I would suggest that you purchase a hand strength grip trainer from a sporting goods shop and start using it every day to build hand strength. Because it will be of great benefit to increase the strength of your grip. You will also want to start with the 147 grain Target Wadcutters for your initial shooting, they are the mildest recoiling 38 spl. loads you can find commercially. After you get aquainted with that load, and comfortable shooting it, you can then move up to a 158 grain 38 spl. and start up the chain of recoil progression. BTW, I find that in general a heavier bullet produces a LESS SHARP recoil impulse than loadings that feature a lighterr bullet. As for why, heavier bullets move slower and this means the timespan of the recoil impulse is increased, which has the effect of making it feel milder.
However, one negative of choosing a heavier bullet is the muzzle flash and noise does increase due to the volume of unspent powder that leaves the barrel and then burns off outside of the barrel. Due to this, I would suggest that you do a bit of shopping for the most effective hearing protection you can find. Look for over the ear muffs that offer noise reduction in the 30 to 33 db range and pass on the 24 db cheapies that are so common. In addition to those muffs I would also suggest that you use the in the ear plugs that are free at most shooting ranges. Take it from someone who wakes up every day and goes to sleep every day with a ringing in the ears, you can't ever have too much hearing protection. In addition, being well protected will lessen the tendancy to "jump" when a gun fires.
Finally, seek training from a professional. Most shooting ranges can provide you with training or references for certified trainers. One positive is that you won't be trained in bad habits as can happen with an amateur. In addition, many professional trainers can offer a selection of guns that will allow you to shoot something heavier will less recoil.
To be honest you've been given a gun that is more suited to a very experienced shooter and a rather poor choice for a first time shooter. The good news is that with proper preperation and good training there is no reason at all why you cannot acquire the skills of a very experienced shooter in 4 to 6 months. However, it will require some commitment and dedication.
