Well, I got it in and I think it holds pretty tight to the body, not unhappy at all with that. Yeah, the gun ain't being held in with much retention. Wouldn't go hanging upside down on the monkey bars with it, but hell, I don't do that anyway, LOL. I don't think it'll be a problem for how I'll use the holster. I don't think running will dislodge it.
The one thing I'm not real thrilled about is I thought it'd ride a little higher. Can't lift my arm over shoulder high without exposing at least the barrel of the gun under a normally long untucked T. I have a collection of vests that work well as over-garments, but in summer, they're too hot. I'll just have to keep from reaching with my right hand in the store for something on the upper shelf.
The plus is it seems to be a lot more comfy than any IWB. I have IWBs from Sparks and Rosen and neither are as comfy for long term wear. And, yeah, I think it'll work well in the car. Once a week, I collect from the machines (part time paper route job twice a week to boost my retirement income). I carry in the pocket, but getting the gun out of a pocket while seated in a car is a bit tricky. IWB is better, but the seats in the car aren't conducive to 4 o'clock carry, wrap around buckets. This thing carries at 3 o'clock without bothering my hip bone.
Anyway, while I don't think I'll wear this thing every day, it will be handy for the .357 and I think it'll be handy when I'm collecting. It will also be nice to carry the 4" gun when I check the hog trap at my place or go down there to work on something. I normally don't bother with a belt gun, but if I can wear it on the belt concealed, hey, why not?
I'm pretty happy with it, especially that I don't have a lot of money in it. It contributes to the overall collection of systems for carry and I might actually use it once in a while, LOL.
