I have the DeSantis clip grip on my 340 and use the clip mostly with pocket carry, although then it is kind of open carry. The clip isn’t really long enough over a thick belt, so I don’t carry it IWB with the clip part. I prefer the frame mounted clips for that method. The plastic is durable with some serrations to allow enough texture, so it’s not the worst type of grip for shooting. Overall I find the clip useful enough to outweighs its shortcomings. Plus it still fits in my IWB holster.
