Need to clarify if just shooting it a lot, or planning to CCW as well.
The SP 101 is a great gun, as mentioned before it is a bit heavy. Most Folks using a good belt and holster have no problem with CCW. Most Folks I know use OWB. I'm sure IWB works fine, just seems the folks I know prefer the OWB - must be a local deal.
There is a relationship to gun weight and recoil. I prefer steel guns - or - steel guns with Aluminum. Naturally a lighter gun is going to recoil more, which affects shot to shot. Some of the newer alloys do NOT suggest certain bullets, setback can cause the bullets to become unseated - binding the cyl. Something to consider is "is this gun selective on ammo?".
There is a difference in "shooting sometimes" as light gun that recoils heavily. Be it a dedicated .38 spl. or a .357 that one "can" shoot .38spls out of. The truth is most folks with a .357 usually load up with .38spls. Especially if the wife or gf may have to use the gun as well.
I do not recommend a J frame [sized] for new shooters , it takes practice to become good and comfortable with one. Learning and practice with a K frame [sized] is best, then one transitions what learned to the smaller frames.
The Colt Detective Special is a wee bit bigger than a J frame, "feels" like a K frame, and many prefer this gun size and weight. IWB , OWB, even pocket with a holter works great. Six rds instead of a J frame's five. Many folks find they shoot this gun much better than the J frame sized guns.
Now if you want to consider a snubby that is easier to shoot than a J frame, less monies ( usually ) than a Colt DS - find a good used dedicated .38spl in a K frame - such as a Mod 10 or 64. Six shots, a bit heavier, more stock to hold onto, because of larger grip size of the frame.
Now the old Taurus 85, the blued one, many a person bought these and shot the fire out of them. Still running, still being used for CCW as Primary, BUG, deskdrawer gun at the office - whatever. This before the locks were put on the guns. Granted not as smooth a trigger as a Smith or Colt, still with standard pressure 158 gr loads ( like most snubbies, seems to be what shoots POA/ POI best) these are great guns...getting real hard if not impossible to find an OLDer one used. I have a few folks that have who knows how many rds through them, still running, reliable, even if a bit worn on bluing from CCW-ing and using so much.
Naturally I'm going to suggest you try to shoot a variety before you buy. Then if can and not resticted in your jurisdiction to have a gun lock - find a good used Police Trade in , get the stocks that fit you, find the loads it likes and shoots POA/ POI and shoot the durn thing. Learn it and have fun. Back up 50 yds and ring a steel - big grins are expected of course.
DO NOT...shoot a OLDer J frame in .32 or .22lr. Addictive, I take no responsiblity if you do. Just like I don't when I warn a person about a 28 ga shotgun. I still get blamed and all ....still I did warn
them.
