A short-barreled 627 or 327 (scandium/titanium) would be suitable for carry, but a 4" or longer barrel would be better for the OP's stated use, home defense and range.
I agree that the 5" TRR8 is a delight to shoot - quick handling and very accurate. It is a PC product, and mine has a 9.5# DA trigger pull. At just under 36 oz, recoil is not a problem.
I also picked up an used 627 PRO, which has a 4" barrel. It too is a very nice shooter, and much less expensive, new or used, than a TRR8 or 327.
It's not hard to carry a 3" or shorter N-frame in an IWB holster and good belt, for concealment. I've carried a 4" IWB, but it's a lot more comfortable in an OWB holster. A TRR8 will fit any N-frame holster for 5" or longer, if you omit the optional rails.
