The Nyclad in non- +P is a fine round in older snubbies. It's basically a lead hollowpoint with a plastic, or vinyl-like, jacket instead of a copper, or other type of metalllic jacket. 2" barrels don't give the round the opportunity to produce a lot of velocity, which you need to open up a standard jacketed bullet once it hits the target. When a Nyclad hits its target the vinyl coating provides no resistance to the expansion of the lead hollowpoint. This allows the bullet to rapidly dump its energy into the target at the lower velocities produced from the snubbies. Another byproduct of this bullet is that the coating expands with the bullet and helps to keep it together and not fragment, again providing for a more efficient energy dump into the target. The trade-off is less penetration, which may effect its performance in larger people. But you may find that in a similar situation a copper jacketed bullet would not expand well at the lower velocities and would not be as effective.
Years ago I fired some S&W 158 gr. Nyclads into wet phone books, along with Rem 125 gr. +P rounds, out of a Det. Special and was favorably impressed with their preformance. The 125's had greater penetration, but much less expansion, maybe up to .45". The Nyclad penetrated about 3" less, but expanded wonderfully, to well over 1/2", and stayed together.
Recently I acquired a S&W Model 37 and was looking for a non- +P round for it (I was unaware that Nyclad was still in production) and it was recommended to me also. I use the 125 gr. Standard load in the 37 and it is accurate enough for its purpose and recoil is mild. I think you will be satisfied with it.
BTW it does come in 125 gr. and 158gr. +P loads if you like.
